It applies only to sheet moulding compound having glass fibres as the sole or main reinforcement. It should be noted that the term sheet moulding compound covers products which can be complex mixtures and which may differ from the definition of “mat” given in ISO 472. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

The glass reinforcement generally takes the form of chopped or unchopped strands, used alone...
