GB/T 3921 Textiles - Tests for colour fastness - Colour fastness to washing with soap or soap and soda

A Chinese national standard test method. China produces more textiles than any other country, and a specification written there cites GB designations rather than ISO or ASTM ones.

ISO ISO 105-C10 NEQ SAMR titles this standard "Colour fastness to washing with soap or soap and soda", word for word the title of ISO 105-C10. This register's own ISO 105-C06 record already says GB/T 3921 is aligned to C10 rather than C06. Recorded as NEQ - related in subject - and not as MOD or IDT: SAMR flags that some GB standards adopt an international standard but never names which, so the degree of alignment is not evidenced here. A person with the full text can raise it.
What this standard is for

What to watch for

The title is SAMR's own English title for this standard, published beside the Chinese one - not a translation made here. The Chinese text is the standard; the English title is how SAMR names it.
