Then there will be a question always from my clients,  will the background material color (the elastic strap) affect the EN17353 certificate?

Here is the answer from Satra Lab

Will The Background Material Color Of Reflective Harness Effect The EN17353 Certificate Issue

in the Satra email we can see below comment:

This means we will accept cross belts with orange and yellow/green background material on them – if they do not claim to be for daylight and night use (AB3), but claim nighttime use only (B3).

This does mean that we could use the reflective values for cross belt 19-1193 to certify orange and yellow variants of that item without having to do any additional work.

so we know that because the harness is used for nighttime, the background color of the straps will not affect its function. Just keep the reflective material more than 800cm2 for adult size and 600cm2 for children size.  and must use high-quality reflective material. below is the requirements forEN 17353:2020 Minimum coefficient of luminous intensity R(CIL) for type AB devices

the requirements forEN 17353:2020 Minimum coefficient of luminous intensity R(CIL) for type AB devices

Overall, keep 2 main points:  1, reflective area  2, high reflective,  the strap material color will not have any affection for EN17353.
