EN471, reflective uniforms are divided into three grades, each of which has different requirements for the minimum area of reflective material.

BS EN 471:2003

High-visibility warning clothing for professional use- Test methods and requirements

Reflective material

4.Design design

4.1 reflective uniforms are divided into three grades. Each level has different requirements for the minimum area of reflective materials.

4.2 special requirements

4.3 size (EN 340)

5. requirements for background materials, non fluorescent materials and composite functional materials.

5.1 the color function requirements of the new material

5.1.1 background material

In the interval of Table 2, the luminosity coefficient should exceed the corresponding minimum value in Table 2.

5.1.2 comprehensive functional materials (functions of background materials and reflective materials)

In the interval of Table 2, the luminosity coefficient should exceed the corresponding minimum value in Table 2.

The average brightness coefficient of horizontally sensitive reflective materials should be measured at two rotation angles of 7.3 kinds.

The dyeability of horizontally sensitive reflective materials should be measured in the 7.3 two rotation angles.

Color function requirements after 5.2 light tests

According to the ISO 105 - B02:1994 method 3, light, red and orange, 5 grade standard blue wool to 3, for yellow material, and grade 4 Blue Sheep
