Standards crosswalk

ISO

ISO appears on 1,355 crosswalks here — as the issuing body, or as an equivalent to another body's standard.

Any body’s number. It lands on the crosswalk that covers it, whichever body issued it.

International Organization for Standardization

The international consensus standard, and usually the one a crosswalk is filed under. Textile test methods sit in technical committee TC 38.

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 1833-18

Textiles — Quantitative chemical analysis — Part 18: Mixtures of silk with wool or other animal hair (method using sulfuric acid)

Silk dissolved in sulfuric acid, leaving wool or other animal hair. Two protein fibres separated on their different resistance to acid - a narrow margin, and the reason…

ISO 1833-19

Textiles — Quantitative chemical analysis — Part 19: Mixtures of cellulose fibres and asbestos (method by heating)

Cellulose burned away by heating, leaving asbestos - a loss-on-ignition method rather than a dissolution, so there is no reagent and no correction factor d. Retained for legacy…

ISO 1833-2

Textiles — Quantitative chemical analysis — Part 2: Ternary fibre mixtures

Ternary mixtures - three fibres rather than two. It is the hardest arithmetic in the series because it needs two successive dissolutions on separate specimens, and each carries…

ISO 1833-20

Textiles — Quantitative chemical analysis — Part 20: Mixtures of elastane with certain other fibres (method using dimethylacetamide)

Elastane dissolved in dimethylacetamide, leaving the ground fibre. Every stretch fabric needs this one, and elastane is the component most often mis-declared: it is present in small percentages…

ISO 1833-21

Textiles — Quantitative chemical analysis — Part 21: Mixtures of chlorofibres, certain modacrylics, certain elastanes, acetates, triacetates with certain other fibres (method using cyclohexanone)

Chlorofibres, some modacrylics, some elastanes, acetates and triacetates dissolved in cyclohexanone. The alternative to Part 12 and Part 13 for several of the same fibres, with a less…

ISO 1833-22

Textiles — Quantitative chemical analysis — Part 22: Mixtures of viscose or certain types of cupro or modal or lyocell with flax fibres (method using formic acid and zinc chloride)

Viscose, cupro, modal or lyocell dissolved in formic acid with zinc chloride, leaving flax. The linen-blend counterpart of Part 6, and it carries the same difficulty: flax and…

ISO 1833-24

Textiles — Quantitative chemical analysis — Part 24: Mixtures of polyester and certain other fibres (method using phenol and tetrachloroethane)

Polyester dissolved in phenol with tetrachloroethane. The method for proving polyester content when the other component would not survive the sulfuric acid route - it dissolves the polyester…

ISO 1833-25

Textiles — Quantitative chemical analysis — Part 25: Mixtures of polyester with certain other fibres (method using trichloroacetic acid and chloroform)

Polyester dissolved in trichloroacetic acid with chloroform. The second polyester-dissolving route, for blends where phenol and tetrachloroethane are unsuitable or unavailable. The residue is weighed and corrected by…

ISO 1833-26

Textiles — Quantitative chemical analysis — Part 26: Mixtures of melamine with certain other fibres (method using hot formic acid)

Melamine fibres separated using hot formic acid. Melamine is a flame-resistant fibre found in protective clothing and upholstery, and blends containing it are usually being tested because a…

ISO 1833-27

Textiles — Quantitative chemical analysis — Part 27: Mixtures of cellulose fibres with certain other fibres (method using aluminium sulfate)

Cellulose fibres dissolved with aluminium sulfate. A gentler route than the sulfuric acid parts, for residues that concentrated acid would damage. The residue is weighed and corrected by…
