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 1833-26

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 1833-28

Textiles — Quantitative chemical analysis — Part 28: Mixtures of chitosan with certain other fibres (method using diluted acetic acid)

Chitosan dissolved in dilute acetic acid. Chitosan appears in antimicrobial and medical textiles, usually in small proportions, and this part exists because it dissolves in conditions that leave…

ISO 1833-29

Textiles — Quantitative chemical analysis — Part 29: Mixtures of polyamide with polypropylene/polyamide bicomponent (method using sulfuric acid)

Polyamide dissolved in sulfuric acid, leaving the polypropylene side of a polypropylene/polyamide bicomponent fibre. The newest problem in the series: a bicomponent fibre is one fibre made of…

ISO 1833-3

Textiles — Quantitative chemical analysis — Part 3: Mixtures of acetate with certain other fibres (method using acetone)

Acetate dissolved in acetone, leaving the other fibre behind. The workhorse method for acetate blends, and the one to reach for before the benzyl alcohol or acetic acid…

ISO 1833-4

Textiles — Quantitative chemical analysis — Part 4: Mixtures of certain protein fibres with certain other fibres (method using hypochlorite)

Protein fibres - wool, silk, other animal hair - destroyed by hypochlorite, leaving cellulosics or synthetics. Hypochlorite is aggressive: over-running it attacks the residue as well, which shows…

ISO 1833-7

Textiles — Quantitative chemical analysis — Part 7: Mixtures of polyamide with certain other fibres (method using formic acid)

Polyamide dissolved in formic acid, leaving wool, cotton, polyester and most other fibres. One of the cleanest separations in the series, which is why nylon blends are among…

ISO 1833-8

Textiles — Quantitative chemical analysis — Part 8: Mixtures of acetate and triacetate fibres (method using acetone)

Acetate dissolved in acetone, leaving triacetate. Separating two fibres of the same chemical family on nothing but their degree of acetylation, which is why the timing and temperature…

ISO 1833-9

Textiles — Quantitative chemical analysis — Part 9: Mixtures of acetate with certain other fibres (method using benzyl alcohol)

Acetate dissolved in benzyl alcohol. The route for acetate blends where the other component would not survive acetone, or where acetone fails to separate them cleanly. The residue…
