Standards crosswalk

CEN

CEN appears on 410 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.

European Committee for Standardization

Publishes EN standards, which member countries adopt under their own prefixes — the same document appears as BS EN, DIN EN and NF EN.

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 1833-10

Textiles — Quantitative chemical analysis — Part 10: Mixtures of triacetate or polylactide with certain other fibres (method using dichloromethane)

Triacetate or polylactide dissolved in dichloromethane. The polylactide case matters more each year as PLA appears in compostable and bio-based textiles, and it is easy to misread as…

ISO 1833-11

Textiles — Quantitative chemical analysis — Part 11: Mixtures of certain cellulose fibres with certain other fibres (method using sulfuric acid)

Cellulose fibres dissolved in sulfuric acid, leaving polyester, polypropylene and other acid-resistant synthetics. The standard method for proving the synthetic content of a cotton-polyester blend, which is most…

ISO 1833-12

Textiles — Quantitative chemical analysis — Part 12: Mixtures of acrylic, certain modacrylics, certain chlorofibres, certain elastane fibres with certain other fibres (method using dimethylformamide)

Acrylic, some modacrylics, some chlorofibres and some elastanes dissolved in dimethylformamide. The part that covers the widest set of fibres, and correspondingly the one where identifying the fibre…

ISO 1833-13

Textiles — Quantitative chemical analysis — Part 13: Mixtures of certain chlorofibres with certain other fibres (method using carbon disulfide/acetone)

Chlorofibres dissolved in carbon disulfide with acetone. The reagent is flammable and acutely toxic, and this method should not be attempted outside a fume cupboard by anyone who…

ISO 1833-14

Textiles — Quantitative chemical analysis — Part 14: Mixtures of acetate with certain other fibres (method using glacial acetic acid)

Acetate dissolved in glacial acetic acid. The third acetate route in the series, after acetone and benzyl alcohol - the series offers several because the right one depends…

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 1833-2

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 1833-22

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…
