REQUIREMENTS FOR BACKGROUND MATERIAL, NON-FLUORESCENT MATERIAL AND COMBINED PERFORMANCE MATERIAL
Colour performance requirements of new material.
Background material: The chromaticity coordinates shall be within the areas defined by the following table and the luminance factors shall comply with the requirements specified on the same table.
Colour after the Xenon test: The colour after exposure shall be within the areas defined by the coordinates in the previous table for background materials and combined performance materials and its luminance factor shall comply with the minimum value for the luminance factor (previous table) of the colour that is obtained on exposure to Xenon light.
A fluorescent red is acceptable if after exposure to Xenon light its colour-coordinates are within the tolerated area for orange-red and if its luminance factor is higher than 0,4.
Exposure shall continue until the blue scale control standard number 5 has changed to grade 3 of the grey scale for red and orange-red materials and for yellow materials the blue scale control standard number 4 has changed to grade 4 of the grey scale.
Colour after washings: If the manufacturer specifies a maximum number of washing cycles, the colour should be within the areas specified by the mentioned coordinates and the luminance factor should be at least the one specified for each colour after the maximum number of washings defined.
If the number of washing cycles is not specified, the tests shall be carried out after 5 washing cycles. .
Dimensional change: The requirements and testing procedures for dimensional change on materials shall comply with ISO13688.
Tensile strength: Tensile strength: the tensile strength in weft and warp direction shall be at least 100 N.
Bursting strength of knitted materials : when tested in accordance with ISO 13938-1 or ISO 13938-2 using a 50 cm2test area, the burst strength of knitted outer material shall have a mean minimum of 100 kPa or, using a 7,3 cm2 test area shall be a minimum of 200 kPa.
Water vapour and thermal resistance: For garments which offer protection against rain (coated woven and knitted fabrics and laminates), test and classify in accordance with EN 343.
For other single or multilayer garments, the water vapour resistance shall be lower than 5 m2 Pa/W. If the water vapour resistance exceeds 5 m2 Pa/W, the thermal resistance according to ISO 11092 shall be measured and the water vapour permeability index shall be determined. The water vapour permeability index shall be >= 0,15.
