AATCC TM15 sweat resistance color stability test method

core purpose 

AATCC @ TM15 Sweat resistance color stabilization test (artificial sweat method) is designed to determine the color stability of textile / toy coatings / materials in an environment simulating human sweat and to prevent color degradation and segmentation; At the same time, in conjunction with toy safety requirements, limit the mobility of heavy metals in toy materials and block thehealth risks of children's intake of heavy metallics through exposure, mouthfuls, and sweatexposure. Version 2021 has consolidated the revised content of 2023 to double ensure thesafety of children' use.

Standard definition

Scope of application AATCC TM15 applies to alltypes of textiles, toy contact coatings, fabrics, leather, plastic surfaces, liquid /gel toy parts, and toy materials that are in permanent contact with human sweat; Control of heavy metals in toys applies to oral contact toys, children's toys under 72 months of age, contactablecoatings, liquid /gel toys and parts; Material that is only packaged and has no play value is not applicable. Key terms Sweat resistance: the ability of a material to resist color change, fading, and stain onto a lined fabric under the action of artificial acid / alkaline sweat, Element migration: The content of eight heavy metals such as antimony, arsenic, cadmium and lead dissolved in toy materials in an environment simulating human physiology / sweat.

Testing and certification requirements

Color fastness: TM8 with dry /wet friction cloth reciprocating test, TM15 by artificial sweat impregnation, constant temperature pressure, with gray sample card rating (5 best).

Heavy metals: Controlling the migration of eight major elements such as antimony and arsenic, sampling and testing according to Australian and NewZealand standards. Certification: Requires a third-party inspection approved by ANZ, report retention; Product labels age appropriate.
