New ISO-527-1 2nd Edition for Plastics – Determination of tensile properties – Part 1: General principles

There’s a new ISO 527-1:2012 available from Document Center Inc.  Titled “Plastics – Determination of tensile properties – Part 1: General principles,” the 28-page revision specifies the general principles for determining the tensile properties of plastics and plastic composites under defined conditions. Several different types of test specimen are defined to suit different types of material which are detailed in subsequent parts of ISO 527.

The methods are used to investigate the tensile behaviour of the test specimens and for determining the tensile strength, tensile modulus and other aspects of the tensile stress/strain relationship under the conditions defined.

The methods are not normally suitable for use with rigid cellular materials, for which ISO 1926 (Rigid cellular plastics – Determination of tensile properties) is used, or for sandwich structures containing cellular materials.

This second edition cancels and replaces the first edition (ISO 527‑1:1993), which has been technically revised. It incorporates ISO 527-1:1993/Cor 1:1994 and ISO 527-1:1993/Amd 1:2005.

The main changes to ISO 527-1 are as follows:
— A method for the determination of Poisson’s ratio has been introduced. It is similar to the one used in ASTM D638 (Standard Test Method for Tensile Properties of Plastics), but in order to overcome difficulties with precision of the determination of the lateral contraction at small values of the longitudinal strain, the strain interval is extended far beyond the strain region for the modulus determination.
— Definitions and methods have been optimized for computer controlled tensile test machines.
— The preferred gauge length for use on the multipurpose test specimen has been increased from 50 mm to 75 mm. This is used especially in ISO 527-2.
— Nominal strain and especially nominal strain at break will be determined relative to the gripping distance. Nominal strain in general will be calculated as crosshead displacement from the beginning of the test, relative to the gripping distance, or as the preferred method if multipurpose test specimens are used, where strains up to the yield point are determined using an extensometer, as the sum of yield strain and nominal strain increment after the yield point, the latter also relative to the gripping distance.

The 2nd Edition for Part 2, “Plastics — Determination of tensile properties — Part 2: Test conditions for moulding and extrusion plastics,”  has also been released at the same time.  ISO 527-2:2012 specifies the test conditions for determining the tensile properties of moulding and extrusion plastics, based upon the general principles given in ISO 527‑1.
