Plastics — Acquisition and presentation of comparable multipoint data —

Part 1: Mechanical properties

1 Scope

This document specifies test procedures for the acquisition and presentation of multipoint data on the following mechanical properties of plastics:

— dynamic modulus;

— tensile properties at constant test speed;

— ultimate stress and strain;

— tensile stress-strain curves;

— tensile creep;

— Charpy impact strength;

— puncture impact behaviour.

The test methods and test conditions apply predominantly to those plastics that can be injection- or compression-moulded or prepared as sheets of specified thickness from which specimens of the appropriate size can be machined.

multipoint data

data characterizing the behaviour of a plastics material by means of a number of test results for a property measured over a range of test conditions

4 Specimen preparation

In the preparation of specimens by injection or compression moulding, the procedures described in ISO 293, ISO 294-1 and ISO 294-3, ISO 295 or ISO 10724-1 and ISO 10724-2 shall be used. The method of moulding and the conditions depends upon the material being moulded. If these conditions are specified in the International Standard appropriate to the material, then they shall be adopted, where possible, for the preparation of every specimen on which data are obtained using this document. For those plastics for which moulding conditions have not yet been standardized, the conditions employed shall be within the range recommended by the polymer manufacturer and shall, for each of the processing methods, be the same for every specimen. Where moulding conditions are not stipulated in any International Standard, the values used for the parameters in Table 1 shall be recorded with the data for that material.

Where specimens are prepared by machining from sheet, the machining shall be performed in accordance with ISO 2818.
