| UNE EN ISO 471 HIGH-VISIBILITY CLOTHING FOR CERTIFIED WORKWEAR Fabrics which meet this EN ISO standard:
| |||||||||||||||||||||||
| GENERAL REQUIREMENTS | |||||||||||||||||||||||
| ISO 13688 | Sizes: according ISO 13688. | ||||||||||||||||||||||
| | Design: High-visibility garments are grouped in three classes. Each one has to have a minimum surface of the visible fabrics which compose the garment according the following table. The garments have to consist in the required surface of High-visibility fabric and retrofeflective tapes or in the demanded surface of combined material.
The proportion of the demanded fabric has to be around the 50% ± 10% on the front and back of the garment. This one has to be measured over a flat surface, including trunk, arms and legs. There are specific requirements for garment design. | ||||||||||||||||||||||
| REQUIREMENTS RELATED TO THE HIGH-VISIBILITY FABRIC, NOT FLUORESCENT MATERIAL AND TO THE COMBINED FABRIC | |||||||||||||||||||||||
| | Feature requirements of colour for new fabrics. High-visibility fabric: the chromatic coordinates have to be placed inside one of the defined areas from the following table and the luminance factor has to be superior to the minimum corresponding figure from the same table. Combined fabric: the chromatic coordinates have to be placed inside one of the defined areas from the following table and the luminance factor has to be superior to the minimum corresponding figure from the same table.
| ||||||||||||||||||||||
| ISO 105-B02 | Colour after the Xenon test: After the exposition to artificial light of Xenon, the colour has to be between the defined areas by the coordinates from the previous table and the luminance factor has to be superior to the minimum value required for each colour. In the case of the red colour, after the exposition to Xenon, its coordinates and luminance can pass to the graph from the red-orange colour. For the yellow fabrics, the exposition has to continue until the level 4 from the blue scale changes to reach the level 4 from the grey scale. For the red and red-orange fabrics, the exposition has to keep going until the level 5 from the blue scale changes to reach the level 3 from the grey scale. | ||||||||||||||||||||||

| MECHANICAL PROVISIONS | |||||||||||||||||||||||
| EN 340 | Dimensional variations: The fabric requirements and testing procedures have to satisfy the norm EN 340. | ||||||||||||||||||||||
| ISO 13934-1 | Resistance to tensile strength: The resistance to tensile strength in newtons, divided by the specific weight of the fabric, expressed in g/sqm, has to be ≥ 2 and with a minimum value of 400 N. | ||||||||||||||||||||||
| ISO 13938-1 | Resistance to bursting for knitted fabrics: the fabrics should reach a resistance al bursting at least of 800 kN/m2. The size of the sample to test will be of 30 mm of diameter. | ||||||||||||||||||||||
| EN 31092 | Water vapour resistance: The water vapour resistance from the laminated fabrics has to be classified according to the norm EN 343, and doesn’t have to be superior to 5 sqmPa/W | ||||||||||||||||||||||
