This document specifies the framework, concepts, methodology for testing, and criteria to be achieved to claim conformance to multiple parts of the ISO/IEC 21122 series. It lists the conformance testing procedures.
Plastiques — Détermination du taux de cendres — Partie 5: Poly(chlorure de vinyle)
Le présent document spécifie trois méthodes pour la détermination du taux de cendres du poly(chlorure de vinyle).
Les modes opératoires généraux donnés dans l’ISO 3451-1 sont suivis. Pour les cendres, la méthode A est utilisée. Pour les cendres sulfatées, les méthodes B et C sont utilisées. Les trois méthodes s’appliquent aux résines, compositions et produits finis. Les méthodes B et C sont…
Plastics — Determination of dynamic mechanical properties — Part 10: Complex shear viscosity using a...
This document specifies the general principles of a method for determining the dynamic rheological properties of polymer melts at angular frequencies typically in the range of 0,01 rad s-1 to 100 rad s-1 by means of an oscillatory rheometer with a parallel-plate or a cone-and-plate geometry. Angular frequencies outside this range can also be used.
The method is applicable for determining values…
Air intake filter systems for rotary machinery — Part 4: Test methods for static filter systems in c...
This document defines test methods for performance testing of individual filter elements and of the complete filtration system.1)
This procedure is intended for filter elements and filter systems which operate at flow rated up to 8 000 m3/h per filter element.
1) The filters will be loaded with ultra-fine salt particles of a size mostly sub micron during variable humidity to simulate real…
Plastics — Determination of ash — Part 5: Poly(vinyl chloride)
This document specifies three methods for the determination of the ash of poly(vinyl chloride).
The general procedures given in ISO 3451-1 are followed. For ash, method A is used. For sulfated ash, methods B and C are used. All three methods are applicable to resins, compounds and finished products. Methods B and C are applicable when lead-containing compounds are present.
