Leather testing standards

 

Bag testing will involve leather testing, so what is leather testing it, what are the items of leather testing, and what is the standard, take you to understand the standards and projects of leather testing.

Chemical performance test: pH, hexavalent inscription content, formaldehyde content, prohibited azo dyes, odor, fur volatiles content volume, leather water content and volatiles

 

Color fastness: rubbing color fastness, color fastness to water stains, color fastness to perspiration stains, color fastness to light

 

Content determination: formaldehyde content, hexavalent chromium, azo, heavy metals, PCP, TeCP, OPP, free fatty acid content amount, organic tin compounds

 

Material identification: material identification (leather, fur/artificial leather/synthetic leather, etc.)

 

Analysis items: composition analysis, toxic and harmful substances detection, environmental protection detection, azo test
