"7.4	Test for projections and surface friction

7.4.1.	Test for projections and surface friction (method A)

7.4.1.1.	Description of test

7.4.1.1.1.	Principle

The rotation-inducing forces caused by projections on the helmet and friction against the outer surface of the helmet which occur when a helmeted headform is dropped vertically on to an inclined anvil are measured in the longitudinal axis of the anvil. The peak force and its integral with respect to time over the duration of the positive impulse are used as performance criteria.

7.4.1.1.2.	Selection and positioning of the helmet

7.4.1.1.2.1.	An appropriate size helmet shall be selected to fit the headform referred to in paragraph 7.4.1.2.6. The horizontal axis of the helmet shall be determined by placing the helmet on a headform, of a type referred to in paragraph 7.3.3., according to the requirements of annex 5. The helmet shall then be removed from that headform and placed on a headform of a type referred to in paragraph 7.4.1.2.6. A load of 50 N is applied to the crown of the helmet in order to adjust the helmet on the headform such that there is contact between the crown of the headform and the inner surface of the helmet. The horizontal plane of the helmet shall then be adjusted to be within 90 ± 5 of the vertical axis of the headform. The retention system is then adjusted under the chin of the headform; if the system includes an adjustable chin strap, the strap is tightened as much as possible.

7.4.1.1.2.2.	The test headform shall be so positioned that the chosen impact point on the helmet is vertically above the upper part of the face of the anvil.

7.4.1.1.2.3.	The helmet shall be tested in any condition in which it may be placed on the market, that is both with and without accessories if they are supplied as original equipment. Helmets placed on the market with a visor shall be tested with the visor in the closed position.

7.4.1.1.3.	Test

The drop height shall be such that the unit constituted by the headform and helmet falls on the test anvil at a velocity which, immediately before impact, is equal to 8.5 (-0.0/+0.15) m/s.

7.4.1.2.	Apparatus (see annex 8, fig. 1b)

7.4.1.2.1.	Description

The test apparatus shall comprise:

An anvil rigidly fixed to a base;

A free fall guidance system;

A mobile system supporting the helmeted headform;

A headform conforming to that referred to in paragraph 7.4.1.2.6., and

A system which may be adjusted such that the point of impact can be brought into correspondence with the upper part of the face of the anvil.

A means of recording the continuously changing transmitted anvil force during the impact.

A suitable energy-absorbing base and catch net to prevent damage to the helmet after the impact.

7.4.1.2.2	Base

This shall conform to the requirements specified in paragraph 7.3.2.2.

7.4.1.2.3.	Anvil

7.4.1.2.3.1	The anvil is mounted securely at an angle of 15° to the vertical with provision for fore-and-aft adjustment. The anvil has a minimum width of 200 mm and is adaptable to carry either of two different impact surfaces as follows:

7.4.1.2.3.1.1.	The bar anvil consists of a series of at least 5 horizontal bars at 40 mm centres. Each bar is made from a steel strip of height 6 mm and width 25 mm with its uppermost edge machined to a 1 mm radius and the lower 15 mm of its face chamfered at an angle of 15° so that, as mounted, the upper edge of each bar is fully exposed from vertically above. The bars are case-hardened to a depth of approximately 0.5 mm.

The bar anvil should be used to assess the tangential forces and their integrals with time caused by projections on the helmet, e.g. visor fittings, screws, press studs and steps in the shell surface, etc.

7.4.1.2.3.1.2.	The abrasive anvil is a sheet of grade 80 closed-coat aluminium oxide abrasive paper with a minimum supported length of 225 mm and is securely clamped to the base of the anvil to prevent slippage.

The abrasive anvil should be used to assess the tangential forces and their integrals with time caused by friction against the outer surface of the helmet. This is particularly applicable to selected areas of helmets, the outer surface of which either have significant variations of curvature or are made of more than one material.

7.4.1.2.3.2.	The anvil is fitted with force transducer(s) connected to recording apparatus so that the transmitted longitudinal force component can be measured and continuously recorded with an accuracy of ± 5 per cent during a glancing blow to any part of its exposed surface.

7.4.1.2.4.	Mobile system and guides

The mobile system supporting the headform shall be such that its characteristics do not affect the measurement of force in the anvil. It shall also be such that any point in the area above the line ACDEF can be positioned vertically above the anvil. The guides shall be such that the impact velocity is not less than 95 per cent of the theoretical velocity.

7.4.1.2.5.	Force and measuring assembly

The force transducers fitted to the anvil shall be capable of withstanding a maximum force of 20 000 N without damage. The measuring system including the anvil assembly shall have a frequency response in accordance with channel frequency class (CFC) 1 000 of the International Standard ISO "Road vehicles - Techniques of measurement in impact tests - Instrumentation" (Ref. No. ISO 6487:1980).

7.4.1.2.6.	Headform

The headform shall be that referred to in paragraph 7.3.3. characterised by the symbol J.

7.4.1.3.	Selection of impact points

Any point above the line ACDEF on the helmet shell may be selected. The impact point should be selected with regard to the anvil against which the helmet is to be tested, taking into account the function of the anvils given in paragraphs 7.4.1.2.3.1.1. and 7.4.1.2.3.1.2. The helmet shall be tested as many times as necessary to ensure that all notable features are evaluated.

When the bar anvil is used, evaluate all different external projections greater than 2 mm above the outer surface of the shell. Re-orientate the helmet as necessary to allow any specific projection to be impacted from the direction that is likely to produce the greatest force and/or the greatest impulse where impulse is the integral of force with respect to time over the duration of the impact.

Note: The primary impact site on any projection is likely to be opposite to the site where the projection receives maximum support. For example, the primary impact site on a visor cover plate assembly is opposite to the area where the visor and cover plate locates in a recess in the shell.

When the abrasive anvil is used, evaluate the front, rear sides and crown areas of the helmet, selecting within the general areas, sites on the outer surface which are likely to produce the greatest force and/or the greatest impulse where impulse is the integral of force with respect to time over the duration of the impact. Examples of such areas are those having least curvature or areas having more than one type of surface finish, for example a painted shell partially overlaid by a fabric cover.

The rim of the shell and the upper and lower edge of the visor situated within an area bounded by a sector of 120° divided symmetrically by the vertical longitudinal plane of symmetry of the helmet do not constitute a projection for the purpose of this test.

7.4.1.4.	Requirements

7.4.1.4.1.	When tested against the bar anvil the helmet shall satisfy the following requirements:

7.4.1.4.1.1.	the peak longitudinal force measured on the anvil shall not exceed 2 500 N, nor shall its integral with respect to time over the duration of the impact exceed 12.5 Ns for any of the selected impact points.

7.4.1.4.2.	When tested against the abrasive anvil, a second helmet shall satisfy the following requirements:

7.4.1.4.2.1.	the peak longitudinal force measured on the anvil shall not exceed 3 500 N, nor shall its integral with respect to time over the duration of the impact exceed 25 Ns for any of the selected impact points."

7.4.2.	Test for projections and surface friction (method B)

7.4.2.1.	Description of test

7.4.2.1.1.	Principle

The rotation-inducing forces caused by projections on the helmets and friction against the outer surface of the helmets are assessed firstly by a shear impact on the projections using a shear edge against which the projections shall shear away, be detached, or permit the shear edge to slide past the projections. The friction is assessed by the displacement of a carriage abrading the outer surface of the helmet. The shear impact and abrading carriage displacement are generated by a drop weight device.

7.4.2.1.2.	Positioning of the helmets

7.4.2.1.2.1.	The helmet is placed on a headform of appropriate size in accordance with the requirements of annex 5. The helmet is tipped towards the rear so that the front edge of the helmet in the median plane is displaced by 25 mm; if the helmet includes an adjustable chin strap, the strap shall be tightened as much as possible. The headform shall be so positioned that the chosen location on the helmet can be positioned in contact with the upper surface of the horizontal carriage.

7.4.2.1.2.2.	The helmet shall be tested in any condition in which it may be placed on the market, that is both with and without accessories if they are supplied as original equipment. Helmets placed on the market with a visor shall be tested with the visor in the closed position.

7.4.2.1.3.	Test

7.4.2.1.3.1.	Test of projection

The headform is adjusted in order to have the chosen projection on the carriage so that the shear edge is positioned 50 mm from the projection and makes lateral contact with the projection after the drop weight is released from its upper position.

7.4.2.1.3.2.	Test of outer surface

The abrasive paper is mounted on the carriage in the position specified in paragraph 7.4.2.2.2. The chosen outer surface of the helmet is lowered on to the abrading carriage at the centre of the flat surface without abrasive paper. A loading mass is applied in accordance with paragraph 7.4.2.2.8. The drop weight is released from its upper position in accordance with paragraph 7.4.2.2.5. The abrasive paper shall be changed after every test.

7.4.2.2.	Apparatus (a suitable apparatus is illustrated in annex 8, figure 1c)

7.4.2.2.1.	Description

The test apparatus shall comprise:

A horizontal guided carriage with interchangeable attachments for abrasive paper or a shear edge

A horizontal guide and support for this carriage

A roller with a wire rope or a strap or a similar flexible connection

A lever connecting the headform to the test apparatus with a hinge

An adjustable system supporting the headform

A drop weight to load the lower end support of the wire rope, or a strap, after the weight is released

A system to support a headform and to apply a force to the helmet normal to the carriage

7.4.2.2.2.	Carriage

"3.	METHOD (c)

3.1.	Equipment

The test arrangement is shown in figure 3.

Note 1: The measurement principle is identical to the method (a), but the diameter of the measuring is smaller (approximately 2.5 mm) and the test arrangement is simplified.

The beam of the Laser (L) is expanded using the two lenses L1 and L2 and is directed towards the measuring point of the ocular (P). Ocular (P) is positioned in such a way what it can rotate around the axis of the beam.

The deviation of the beam is a function of the prismatic refractive power at the measuring point.

The annular or circular diaphragm, whichever is chosen, is at a distance of (400±2) mm from the centre of the ocular. The lens A then produces the image of the centre of the ocular on the photoreceptor S.

The part of the test arrangement, comprising the diaphragms, the lens and the receptor is designed to rotate about the vertical axis through the centre of the ocular.

The ocular and the detector part of the apparatus has to pivot in order to compensate for any prismatic refractive power of the ocular.

Note 2: For oculars without corrective effect, it is not necessary, in most cases, for the ocular and the detector part to pivot.

3.2.	Procedure

3.2.1.	Calibration of the apparatus

Set up the apparatus, the essential features of which are shown in figure 3, without the ocular in place. Put the annular diaphragm BR in place. Rotate the detector part of the apparatus (consisting of a photoreceptor S, a lens A and the annular diaphragm BR) horizontally about P so as to align the light beam from the beam expander (consisting of a lens L1, with a typical focal length of 10 mm, a lens L2 with a typical focal length of 30 mm and a circular diaphragm B with a pinhole of sufficient size so as to provide a uniform beam) with the centre of the annular diaphragm BR. Measure the flux 1R falling onto the photoreceptor S, corresponding to the total non- diffused light. Replaced the annular diaphragm BR by the circular diaphragm BL.

Measure the flux 1L falling onto the photoreceptor, corresponding to the total non-diffused light.

Obtain the reduced luminance factor for the apparatus, a* , for the solid angle using the following equation:

where 1R	is the luminous flux without the visor in the

parallel beam and with the annular diaphragm BR in place

1L	is the luminous flux without the visor in the

parallel beam and with circular diaphragm BL in place

is the solid angle defined by the annular diaphragm BR

3.2.2.	Testing of the visor

Place the visor in the parallel beam at position P as shown in figure 3. Repeat paragraph 3.2.1. with the visor in place, and with the visor rotated about the axis of the beam to a position such that the prismatic deviation by the visor is horizontal. Rotate the detector part of the apparatus so that the light beam falls on the centre of BR. Obtain the reduced luminance factor for the apparatus including the visor, Ig* , for the solid angle using the following equation:

where 2R	is the luminous flux with the visor in the parallel beam and with the annular diaphragm BR in place

2L	is the luminous flux without the visor in the parallel beam and with circular diaphragm BL in place

is the solid angle defined by the annular diaphragm BR

Then calculate the reduced luminance factor I* of the ocular using the following equation:

Note 1: The focal lengths of the lenses are only given as a guide. Other focal lengths may be used, for example, if a wider beam is desired or a smaller image of the sample is to be formed on the receptor.

Note 2: The diameters of the annular diaphragm circles shall be measured to an uncertainty not exceeding 0.01 mm in order that the solid angle may be determined accurately; any deviation from the nominal diameters shall be taken into account by calculation."

TEST OF REFRACTIVE POWERS

1.	Spherical and astigmatic refractive powers

1.1.	Apparatus

1.1.1.	Telescope

A telescope with an aperture nominally 20 mm and a magnification between 10 and 30, fitted with an adjustable eyepiece incorporating a reticular.

1.1.2.	Illuminated target

A target, consisting of a black plate incorporating the cut-out pattern shown in figure 1, behind which is located a light source of adjustable luminance with a condenser, if necessary, to focus the magnified image of the light source on the telescope objective.

The large annulus of the target has an outer diameter of

(23 ± 0.1) mm with an annular aperture of (0.6 ± 0.1) mm. The small annulus has a inner diameter of (11.0 ± 0.1) mm with annular aperture of (0.6 ± 0.1) mm. The central aperture has a diameter of (0.6 ± 0.1) mm. The bars are nominally 20 mm long and 2 mm wide with a nominal 2 mm separation.

Figure 1: Telescope target

1.1.3.	Filter

A filter with its maximum transmittance in the green part of the spectrum may be used to reduce chromatic aberrations.

1.1.4.	Calibration lenses

Lenses with positive and negative spherical refractive powers of 0.06 m-1, 0.12 m-1 and 0.25 m-1 (tolerance ± 0.01 m-1).

1.2.	Arrangement and calibration of apparatus

The telescope and illuminated target are placed on the same optical axis (4.60 ± 0.02) m apart.

The observer focuses the reticule and the target and aligns the telescope to obtain a clear image of the pattern. This setting is regarded as the zero point of the focusing scale of the telescope.

The focusing adjustment of the telescope is calibrated with the calibration lenses (paragraph 1.2.4.) so that a power of 0.01 m-1 may be measured. Any other calibration method may be used.

1.3.	Procedure

The visor is mounted in front of the telescope as worn and measurements shall be taken at the sign points as specified in paragraph 6.15.3.8.

1.3.1.	Spherical and astigmatic refractive powers

1.3.1.1.	Visors without astigmatic refractive power

The telescope is adjusted until the image of the target is perfectly resolved.

The spherical power of the visor is then read from the scale of the telescope.

1.3.1.2.	Visor with astigmatic refractive power

The target, on the visor, is rotated in order to align the principal meridians of the visor with the bars on the target. The telescope is focused firstly on one set of bars (measurement D1) and then on the perpendicular bars (measurement D2). The spherical

power is the mean, , the astigmatic refractive power is the absolute difference, | D1 - D2 | , of the two measurements.

2.	Determination of the difference in prismatic refractive power

2.1.	Apparatus

The arrangement of the reference method is shown in figure 2.

2.2.1.	Procedure

The diaphragm LB1, illuminated by the light source, is adjusted in such a way that it produces an image on the plane B when the visor (P) is not in position. The visor is placed in front of the lens L2 so that the axis of the visor is parallel to the optical axis of the test assembly.

Adjustable tilt visors are positioned with their ocular regions normal to the optical axis of the equipment.

Measure the vertical and horizontal distance between the two displaced images arising from the two ocular areas of the visor.

These distance in cm are divided by 2 to give the horizontal and vertical prismatic difference in cm/m.

If the light paths which correspond to the two eye regions cross, the prismatic refractive power is 'base in' and if the light paths do not cross, it is 'base out'.

TEST FOR MIST-RETARDANT VISOR

1.	Apparatus

Apparatus to determine the change in the non - diffused transmittance value, as shown in figure 1.

The nominal diameter of the parallel beam is 10 mm. The size of the beam divider, reflector R and lens L3 shall be selected in such a way that diffused light is captured up to an angle of 0.75°. If a lens L3 with a nominal focal length f3 = 400 mm is used, the nominal diameter of a diaphragm is 10 mm. The plane of the diaphragm must lie within the focal plane of the lens L3.

The following focal lengths fi of the lens Li are nominal examples and will not effect the test results:

f1 = 10 mm and f2 = 100 mm

The light source shall be a laser with a wavelength of (600 ± 70) nm.

The volume of air above the water bath is at least 4 litres. The seating ring has a nominal diameter of 35 mm and a nominal height of 24 mm is then measured to the highest point of the seating ring. A soft rubber ring, 3 mm thick and 3 mm wide (nominal dimensions), is inserted between the sample and the seating ring.

The water bath container also contains a ventilator to circulate the air. In addition, there must also be a device to stabilise the temperature on the water bath.

2.	Samples

At least 3 samples of the same type are to be tested. Before the test, the samples are conditioned for one hour in distilled water (at least 5 cm3 water per cm2 sample surface area) at (23 ± 5)°C, then dabbed dry and then conditioned in air for at least 12 hours at (23 ± 5)°C and 50 per cent nominal relative humidity.

3.	Procedure and evaluation

The ambient temperature during the measurement is (23 ± 5)°C.

The temperature of the water bath is set at (50 ± 0.5)°C. The air above the water bath is circulated using a ventilator, so that it becomes saturated with water vapour. During this time, the measurement opening is to be covered. The ventilator is switched off before the measurement.

To measure the change in the value of the transmittance the sample is placed on the seating ring and the time determined until the square of has dropped to less than 80% of the initial value of the sample without fogging (time without fogging).

where:

is the luminous flux when there is fogging on the sample

is the luminous flux before fogging

Initial fogging of maximum 0.5 s duration shall not be taken into consideration in the evaluation.

Note 1: Since the light beam passes through the samples twice, this measurement defines .

Note 2: The period until the start of the fogging can usually be determined visually. However, with some types of coating the formulation of the surface water causes diffusion to increase more slowly so that visual evaluation is difficult. The detection apparatus described in paragraph 1.1. should then be used.
