Migrated from Progress Sheet (TC Comment) (2000-07-10): According to a PC4 recommendation, CEN/BT agreed to launch a parallel voting ++ procedure on the draft international standard derived from the above ++ mentionned subject (Ref.nr. in ISO 11212).
Stärke und Stärkederivate - Schwermetallgehalt - Teil 1: Bestimmung des Arsengehaltes durch Atomabsorptionsspektrometrie (ISO 11212-1:1997)
Dieser Teil von ISO 11212 legt ein Verfahren für die Bestimmung des Arsengehaltes von Stärke, einschließlich von Derivaten und Nebenprodukten, durch Atomabsorptionsspektrometrie mit Hydriderzeugung fest. Die gegenwärtig verfügbaren Hydriderzeuger verwenden sehr verschiedene Verfahren; es ist folglich unmöglich, ein umfassendes Verfahren vorzuschlagen, das das Erreichen von zufriedenstellenden Ergebnissen für alle Gerätetypen sicherzustellt.
Amidons, fécules et produits dérivés - Teneur en métaux lourds - Partie 1: Détermination de la teneur en arsenic par spectrométrie d'absorption atomique (ISO 11212-1:1997)
La présente partie de l'ISO 11212 prescrit une méthode pour la détermination de la teneur en arsenic dans les amidons, fécules, produits dérivés et sous-produits d'amidonnerie par spectrométrie d'absorption atomique avec génération d'hydrures. Les appareils générateurs d'hydrures actuellement commercialisés utilisant des techniques très différentes, il est donc impossible de proposer une méthode détaillée susceptible de garantir l'obtention de résultats satisfaisants sur tous les types d'appareils. Il convient donc que chaque analyste procède à l'optimisation des conditions d'utilisation de son propre instrument sur la base des recommandations générales ou particulières qui lui sont données.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 11212-l was prepared by Technical Committee
ISOmC 93, Starch (including derivatives and by-products).
IS0 11212 consists of the following parts, under the general title Starch
and derived products - Heavy metals content.
- Pall 1: Determination of arsenic content by atomic absorption
spectrometry
- Part 2: Determination of mercury content by atomic absorption
spectrometry
- Part 3: Determination of lead content by atomic absorption
spectrometry with electrothermal atomization
- Pan 4: Determination of cadmium content by atomic absorption
spectrometry with electrothermal atomization

Part 1:
Determination of arsenic content by atomic absorption spectrometry
1 Scope
This part of IS0 11212 specifies a method for the determination of the arsenic content of starch, including
derivatives and by-products, by atomic absorption spectrometry with hybride generation.
The hybride generators currently available use very different techniques; it is thus impossible to propose a
comprehensive method likely to ensure the attainment of satisfactory results on all types of apparatus. Each analyst
should therefore optimize the conditions of use of his/her own apparatus on the basis of general or particular
instructions.
2 Definition
For the purposes of this part of IS0 11212, the following definition applies.
2.1 arsenic content: Quantity of arsenic determined in accordance with the conditions specified in this method
and expressed as arsenic (As), in micrograms per kilogram of the product as received.
3 Principle
Wet digestion of the organic matrix. Reduction of arsenic (As3+) to arsenic hydride by
...
