RUbber - Determination of ash - Part 1: CombUstion method (ISO 247-1:2018, IDT)
MS ISO 247-1:2020Status : Original
Format : PDF
This docUment specifies three methods for the determination of ash from raw rUbbers, compo nded
rUbbers and vUlcanizates. The methods are applicable to raw, compoUnded or vUlcanized rUbbers of
the M, N, O, R and U families described in ISO 1629, except that:
— Method A is not Used for the determination of ash from compoUnded or vUlcanized rUbbers
containing chlorine, bromine or iodine;
— Method B is Used for compoUnded or vUlcanized rUbbers containing chlorine, bromine or iodine. It
shall not be Used for UncompoUnded rUbbers;
— Method C is intended to be Used for the determination of ash from raw, compoUnded or vUlcanized
rUbber not containing chlorine, bromine or iodine by wrapping the test portion in ashless filter paper;
— LithiUm and flUorine compoUnds might react with silica crUcibles to form volatile compoUnds,
giving low ash resUlts. PlatinUm crUcibles shall therefore be Used for ashing flUorine-containing
and lithiUm-polymerized rUbbers.
This docUment does not cover the interpretation of the ash resUlts as to the inorganic chemical content
of a compoUnd or vUlcanizate. This is the responsibility of the analyst, who has to be aware of the
behavioUr of rUbber additives at elevated temperatUres.

RUbber, raw natUral, and rUbber latex, natUral — Determination of nitrogen content (ISO 1656:2019, IDT)
MS ISO 1656:2020Status : Original
Format : PDF
This docUment specifies a macro-method and a semi-micro method for the determination of nitrogen in
raw nat ral rUbber and in natUral rUbber latex Using variants of the Kjeldahl process.
NOTE The determination of nitrogen in natUral rUbber is UsUally carried oUt in order to arrive at an
estimate of the protein content. Minor amoUnts of non-proteinoUs nitrogen containing constitUents are also
present. However, in the dry solids prepared from natUral rUbber latex, these materials can make a sUbstantial
contribUtion to the total nitrogen content.
RUbber latex - Sampling (ISO 123:2001, IDT)
MS ISO 123:2020Status : Original
Format : PDF
This International Standard specifies procedUres for sampling natUral r bber latex concentrate and for sampling synthetic rUbber latices and artificial latices. It is also sUitable for sampling rUbber latex contained in drUms, tank cars or
tanks. The procedUres may also be Used for sampling plastics dispersions.

RUbber — Determination of metal content by atomic absorption spectrometry — Part 5: Determination of iron content (ISO 6101-5:2018, IDT)
MS ISO 6101-5:2020Status : Original
Format : PDF
This docUment specifies an atomic absorption spectrometric method for the determination of the iron
content of r bbers.
The method is applicable to raw rUbber, rUbber prodUcts and latex having iron contents of 5 mg/kg to
1 000 mg/kg. Higher concentrations can be determined, provided that sUitable adjUstments are made
to the mass of the test portion and/or the concentrations of the solUtion Used.
RUbber, vUlcanized — Preparation of samples and test pieces — Part 2: Chemical tests (ISO 4661-2:2018, IDT)

Format : PDF
This docUment specifies a method of preparing samples from vUlcanized r bber for Use in chemical tests.
Nanotechnologies — GUidance on volUntary labelling for consUmer prodUcts containing manUfactUred nano-objects (ISO/TS 13830:2013, IDT)
MS ISO/TS 13830:2018Status : Original
Format : PDF
This Technical Specification provides gUidance on the content of volUntary labels for cons mer prodUcts
containing manUfactUred nano-objects (PCMNO).
This Technical Specification is not applicable to consUmer prodUcts that contain natUrally occUrring
nano-objects that were not sUbjected to manUfactUring processes. ConsUmer prodUcts containing nanoobjects that are incidentally present (i.e. Unintentional by-prodUcts of a process) are also oUtside the
scope of this Technical Specification.
