ISO 6330 Textiles — Domestic washing and drying procedures for textile testing
The washing and drying procedures other tests refer to when they say "after laundering". It prepares the specimen; it does not measure anything itself.

Equivalents
| Body | Number | Equivalence | Deviation |
|---|---|---|---|
| AATCC | AATCC LP1 | NEQ | Parallel laundering practice, not an adoption. Machine types, loads and cycles differ. Note also that AATCC 135 combines the laundering procedure with the dimensional-change measurement, whereas ISO splits these across ISO 6330 and ISO 5077. |
Verification coverage
Checked against AATCC. Not yet checked: ASTM, BIS, SAC, JIS, EN, DIN — an absent row here does not mean no equivalent exists.
What this standard is for
Where it is used
Cited by dimensional-change, colour-fastness and appearance tests, and by retailer care-label protocols.
Why it matters
Almost every after-wash claim on a garment depends on which procedure was used. A fabric that passes at one wash procedure can fail at another, so the procedure named in the protocol is what the claim actually means.
What to watch for
Procedure and machine type must both be stated. "Washed five times" without them says nothing a lab can reproduce.
