BS 3412:1992

This standard BS 3412:1992 Methods of specifying general purpose polyethylene materials for moulding and extrusion is classified in these ICS categories:

• 83.080.20 Thermoplastic materials

This British Standard gives a method for specifying the composition and property requirements of ethylene homopolymers and ethylene copolymers having a maximum content of other 1-olefin monomers of less than 50 % (m/m). In addition, those with a content of non-olefinic monomers with functional groups up to a maximum of 3 % (m/m) are specified in section 2 whilst those particularly for British Government Service contracts having in addition a content of non-olefinic monomers with functional groups up to a maximum of 30 % (m/m) are specified in section 3. This British Standard applies to materials ready for normal use in the form of powder, granules and to materials unmodified by colourants, additives, fillers, etc.

It does not apply to masterbatches or to ethylene-propylene copolymer (EPM rubber).

NOTE The titles of the publications referred to in this standard are listed on page 15.

This revision changes the specification to a method of specifying to incorporate the basic designation system used in ISO 1872-1 and aligns the test methods within those used in ISO 1872-2.
