EN ISO 15797
Procedures for industry laundry and finishing of workwear

EN ISO 15797 is a wash test method used for evaluating textiles / garments that are to be industrially washed and consists of both washing and drying processes. Requirements for test results are determined in the respective EN standard, for example in EN ISO 20471, EN ISO 11612 and EN 1149-5.

On products marked with the PRO symbol, the number of washes the fabric has been washed, before being tested, is indicated, for example 50 washes. This means that the fabric in the garment can be industrially washed at least 50 times without the properties for Flame protection, High Visibility or Anti-Static deteriorating. If the garment is undamaged and in good condition, it can be washed and used more times than the stated number of tests. 

Tranemo performs fabric tests after 50 industrial laundry washes according to EN ISO 15797 of: EN ISO 11612 A1 Surface Ignition, EN ISO 20471 High Visibility and EN 1149-3 Anti-static. Since EN ISO 15797 is always performed on new, clean fabrics where no dirt is involved, Tranemo completes these with ’real’ wearer tests of workwear in combination with washing at our industrial laundry partners to get the most reliable results. After the wearer test and laundry, we then check that the garments still maintain the highest performance. Tranemo also performs internal wash tests before each production to ensure that we maintain the highest performance on fabrics and reflective tapes.
