What are ISO, ASTM and AATCC — and what do IDT, MOD and NEQ mean?
Calculators on this site cite 35 further standards that the register does not cover yet. They are being written in order of how many tools need them.
ISO 139
Textiles — Standard atmospheres for conditioning and testing
The atmosphere every other textile test is supposed to be run in. Textiles absorb and release moisture, so mass, strength and dimensions all move with the room.
ISO 1833-1
Textiles — Quantitative chemical analysis — Part 1: General principles of testing
How the percentages on a composition label are established — dissolving one fibre away and weighing what is left.
ISO 2859-1
Sampling procedures for inspection by attributes — Part 1: Sampling schemes indexed by acceptance quality limit (AQL) for lot-by-lot inspection
The AQL tables behind almost every final garment inspection: how many pieces to pull from a lot, and how many defects allow it to still be accepted.
ISO 4921
Knitting — Basic concepts — Vocabulary
The agreed names for knitted structures and the machinery that makes them. A vocabulary standard rather than a test method, which is why it is cited so widely…
ISO 50001
Energy management systems — Requirements with guidance for use
The management-system standard for energy: how a site measures what it uses, sets a baseline and demonstrates it is improving.
ISO 9001
Quality management systems — Requirements
The management-system standard a buyer means when they ask whether a supplier is certified. It governs how a factory controls its processes, not what its products must achieve.
