ISO 105-X09 Textiles — Tests for colour fastness — Part X09: Colour fastness to formaldehyde

Part of ISO 105, the colour fastness series. Each part covers one agency a coloured textile may be exposed to, or one piece of the apparatus the others are read with - the grey scales, the standard adjacent fabrics, the vocabulary.

What this standard is for

What to watch for

A colour fastness result is not interpretable without knowing which part produced it and which adjacent fabric was used. A rating quoted as "fastness 4" says nothing until the method part is named.
