PrEN 17092: 2018 Parts 1-6
Protective clothing for motorcycle riders
PrEN 17092: 2018 is a new standard currently in development, which is expected to be published in 2019. It will work alongside EN 13595, but will include all clothing marketed as ‘protective clothing for motorcyclists’. It will therefore cover jackets and trousers as well as one- and two- piece suits, and includes a wide variety of tests intended to assess the protection and integrity of the clothing ensemble. It has been formatted into six parts. Part 1 describes the test and examination procedures of the clothing while parts 2 to 6 details the requirements for Class AAA, AA, A, B and C garments.
Impact abrasion resistance (Darmstadt method)
This test simulates the stress that is placed on the protective garments when worn by an average rider with a body mass of 75kg and a height of 1.75m, when sliding from variable initial speeds to standstill on a real concrete road surface.
In one run, three specimens of the material are mounted in holders attached to rotating arms positioned above a concrete tile (road surface). To pass, no holes with an opening of 5mm or more in any direction are to be present on the layer closest to the body.
Strength of seams
Three test pieces of each seam, including all layers of materials from the garment that are present in the seam are tested according to the test procedure in EN 13594:2015. The seam strength is calculated by dividing the breaking force by the length of the tested seam.
For textile garments, six ‘trouser leg’ type specimens are taken from each material of the garment and are torn apart using a standard tensile test machine. For leather garments, six ‘double edged tear’ specimens are taken from each material of the garment and torn apart, also using a standard tensile test machine. Materials shall be tested in two directions - warp and weft.
Impact energy absorption
Elbow, shoulder, knee and hip impact protectors are to be present in Class AAA and AA garments as a mandatory requirement, with the hip protectors being optional in Class A garments. EN 1621 impact protectors must be positioned in the garment so that they cover the appropriate body part, according to the relevant impact protector standard.
Class B garments are designed to provide the equivalent abrasion protection of Class A garments but without the inclusion of impact protectors. Class C garments are designed to provide impact protection for areas covered by the impact protector(s) only, and they do not offer minimum abrasion protection. Class C garments are intended to be worn with and supplement the protection offered by Class AAA, AA, A or B garments.
If the manufacturer’s instructions indicate that garments can be washed or dry cleaned, the test procedure for dimensional change for washing of protective clothing material is to be carried out in accordance with EN 13688. Measurement of dimensional change is carried out according to ISO 5077. Changes in dimension due to cleaning of material must not exceed ±3 percent for woven materials and ±5 percent for knitted material and nonwovens.
Fit and ergonomics
Garments are to fit in accordance with the manufacturer’s size labelling and with the fit information supplied. The assessor must be able to carry out all the essential movements while wearing the test garment and all responses given by the assessor to the series of questions detailed in PrEN 17092-1:2018 must be positive.
Cones are used to exert a circumferential force to the sleeve restraint systems. The restraint systems must withstand this load without opening in order to pass the test.
