BS EN ISO 294-3:2020,Plastics – Injection moulding of test specimens of thermoplastic materials – Part3: Small plates.
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/Aid 1: 2006 The main changes compared to the previous edition are as follows:
—the requirements in Clause 4 have been clarified;
—the position of hc in Figure 2 has been corrected;
BS EN ISO 294-3:2020 specifies two two-cavity moulds, the type Dl1 and D12 ISO moulds, for the injection moulding of small plates measuring 60 mm x 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).
