Plastics - Injection moulding of test specimens of thermoplastic materials - Part 3: Small plates (ISO 294-3:2020)

This document specifies two two-cavity moulds, the type D11 and D12 ISO moulds, for the injection
moulding of small plates measuring 60 mm × 60 mm with a preferred thickness of 1 mm (type D11) or
2 mm (type D12), which can be used for a variety of tests. The moulds can additionally be fitted with
inserts for studying the effects of weld lines on the mechanical properties (see Annex A).

Dieses Dokument legt zwei Zweifachwerkzeuge fest, die ISO Typ D11- und  D12 Werkzeuge zum Spritz¬gießen kleiner Platten 60 mm × 60 mm mit den Vorzugsdicken von 1 mm (Typ D11) oder 2 mm (Typ D12), die für eine Vielzahl von Prüfungen benutzt werden können. Die Werkzeuge können zur Untersuchung der mechanischen Eigenschaften von Fließnähten/Bindenähten zusätzlich mit Einsätzen versehen werden (siehe Anhang A).

Plastiques - Moulage par injection des éprouvettes de matériaux thermoplastiques - Partie 3: Plaques de petites dimensions (ISO 294-3:2020)

Le présent document spécifie deux moules à deux empreintes de type moules ISO D11 et D12 pour le moulage par injection de petites plaques de 60 mm × 60 mm présentant une épaisseur préférentielle de 1 mm (Type D11) ou de 2 mm (Type D12), qui peuvent être utilisés pour de multiples essais. Les moules peuvent, en outre, être équipés d'inserts en vue de l'étude de l'effet induit par les lignes de soudure sur les propriétés mécaniques (voir l'Annexe A).

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9,

Thermoplastic materials, in collaboration with the European Committee for Standardization (CEN)

Technical Committee CEN/TC 249, Plastics, in accordance with the Agreement on technical cooperation

between ISO and CEN (Vienna Agreement).

This third edition cancels and replaces the second edition (ISO 294-3:2002), which has been technically

revised. It also incorporates the Amendment ISO 294-3:2002/Amd 1:2006.
The main changes compared to the previous edition are as follows:
— the requirements in Clause 4 have been clarified;
— the position of h in Figure 2 has been corrected.
A list of all parts in the ISO 294 series can be found on the ISO website.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www .iso .org/ members .html.
