This document establishes a system of designation for thermoplastic PE-UHMW materials, which can be used as the basis for specifications.
For the purposes of this document, PE-UHMW materials are polyethylene materials having a melt mass-flow rate (MFR) of less than 0,1 g/10 min, measured at 190 °C and 21,6 kg load.
NOTE It has been confirmed that the melt volume-flow rate (MVR) is useful…
Plastics — Unplasticized poly(vinyl chloride) (PVC-U) moulding and extrusion materials — Part 1: Des...
This document establishes a system of designation for unplasticized PVC thermoplastic material which may be used as the basis for specifications.
The types of PVC-U plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties
a) Vicat softening temperature,
b) impact strength (Charpy notched),
c) modulus of elasticity…
Water quality — Determination of short-chain polychlorinated alkanes (SCCP) in water — Method using ...
This document specifies a method for the quantitative determination of the sum of short-chain polychlorinated n-alkanes also known as short-chain polychlorinated paraffins (SCCPs) in the carbon bond range n-C10 to n-C13 inclusive, in mixtures with chlorine mass fractions ("contents") between 50 % and 67 %, including approximately 6 000 of approximately 8 000 congeners.
This method is…
Plastics — Poly(vinyl alcohol) (PVAL) materials — Part 2: Determination of properties
This document specifies the methods to be used in determining the properties of poly(vinyl alcohol), which is normally prepared by hydrolysis of poly(vinyl acetate) and whose composition comprises vinyl alcohol monomeric units and vinyl acetate monomeric units. This document is applicable to poly(vinyl alcohol) with a vinyl alcohol unit content (degree of hydrolysis) from 70 mol% to 100 mol%.
