What is SATRA and what are SATRA test methods?

A test result is only useful if it is reproducible. "We flexed the shoe and it was fine" means nothing; "it passed SATRA TM92" means a defined number of flex cycles under defined conditions, and any competent lab will get the same answer. That is what a TM number buys you.

The SATRA methods that matter most in footwear are the whole-shoe ones, because they test the shoe a customer actually wears rather than a swatch of material: TM92 and TM77 for flexing, TM230 for waterproofness, TM161 for bending, TM94 for torsion, TM174 for whole-shoe abrasion, TM411 for sole adhesion, and TM20 and TM21 for heel impact and fatigue.

SATRA methods sit alongside ISO, ASTM, EN and DIN standards rather than replacing them — a single test item often maps to more than one, which is why our testing standards reference lists the standards each test is run to.

DOING runs physical testing in our in-house GOTECH lab and coordinates certification and restricted-substance work at accredited third-party labs. If your specification names SATRA methods, send it — we will tell you which we can run in-house and which we route out.
