ISO 2060 Textiles — Yarn from packages — Determination of linear density (mass per unit length) by the skein method
Establishes what count a yarn actually is, by weighing a measured length of it. Nearly every downstream calculation on a mill floor — fabric weight, consumption, cost per garment — starts from this number, which is why so many of the tools on this site depend on it.

Equivalents
| Body | Number | Equivalence | Deviation |
|---|---|---|---|
| ASTM | ASTM D1907 | NEQ | Parallel standard, not an adoption of the ISO text under ISO/IEC Guide 21. Measures the same property by a comparable method; results should not be assumed interchangeable. Confirm which standard the buyer specifies. |
Verification coverage
Checked against ASTM. Not yet checked: AATCC, BIS, SAC, JIS, EN, DIN — an absent row here does not mean no equivalent exists.
What this standard is for
Where it is used
Yarn purchase specifications and incoming-goods checks at spinning and weaving mills, and in the count claims a spinner makes to a buyer.
Why it matters
A yarn delivered off-count changes fabric weight and therefore fabric cost, and the error compounds through every metre woven. Count disputes are usually settled by re-testing to this method, so the specification named in the contract decides who pays.
What to watch for
Conditioning matters: linear density is mass-based and textiles gain and lose moisture, so a count measured before conditioning to standard atmosphere is not comparable to one measured after. See ISO 139.
