In the Netherlands, all clothing you sell must comply with fire safety standards. There are combustibility tests to determine the fire hazard category. Clothes made of acrylic, modacryl, nylon, olefin, polyester and wool all meet the set requirements. Clothes made of other fabrics can only be sold if accompanied by a test report or a certificate from the supplier indicating that the clothing meets the set requirements. Nightwear must satisfy the requirements in the Fire Safety Agreement for Nightwear (Convenant brandveiligheid nachtkleding, in Dutch). You will find the daywear requirements in the Enforcement Agreements regarding the fire safety of clothing (Commodities Act, in Dutch).
No requirements apply for swimwear, leg fashion, underwear and baby clothes (below size 80).
