ISO 11357 Plastics - Differential Scanning Calorimetry (DSC)

Part 1: Plastics - Differential Scanning Calorimetry (DSC) - Part 1: General Principles

ISO 11357 specifies several differential scanning calorimetry (DSC) methods for the thermal analysis of polymers and polymer blends, such as

• thermoplastics (polymers, moulding compounds and other moulding materials, with or without fillers, fibres or reinforcements);
• thermosets (uncured or cured materials, with or without fillers, fibres or reinforcements);
• elastomers (with or without fillers, fibres or reinforcements).

ISO 11357 is intended for the observation and measurement of various properties of the above-mentioned materials, such as

• physical transitions (glass transition, phase transitions such as melting and crystallization, polymorphic transitions, etc.);
• chemical reactions (polymerization, crosslinking and curing of elastomers and thermosets, etc.);
• the stability to oxidation;
• the heat capacity.

ISO 11357-1:2009 specifies a number of general aspects of differential scanning calorimetry, such as the principle and the apparatus, sampling, calibration and general aspects of the procedure and test report common to all following parts.

Details on performing specific methods are given in subsequent parts of ISO 11357.

AS/NZS 4131 Polyethylene (PE) compounds for pressure pipes and fittings

Part 1: Polyethylene (PE) compounds for pressure pipes and fittings

AS/NZS 4131 specifies requirements for polyethylene compounds (PE 80 and PE 100) suitable for manufacturing polyethylene pipes and fittings for pressure applications. Minimum requirements are given for materials, additives and long-term pressure performance.

Methods of demonstrating compliance with this Standard are given in Appendix A.

Compounds complying with this Standard are not intended for use with gas containing more than 1% aromatics by volume. Where aromatic content is greater than this, testing for resistance to gas constituents should be carried out in accordance with ISO 4437.

AS/NZS 1462.4 sets out the method for determining the degree of residual extrusion stress in plastic pipes by immersion in a heat transfer medium or exposure in a hot air oven. Temperatures of test, times of immersion/exposure and specifications for degree of residual stress shall be as specified in the relevant product standard.

AS/NZS 1462.8 specifies a method for testing the leak tightness of assemblies of plastics pipes and fittings with elastomeric sealing-ring socket joints or inspection openings that may be subject to diametric distortion and/or angular deflection. It includes, but is not limited to -

1. single sockets on pipes,
