IS 7328 : 2020 Specification for Polyethylene Material for Moulding and Extrusion
Revised Standard from Last Update.
Note : [Superseding IS 3395 : 1997]
1 SCOPE
1.1 This standard prescribes the requirements, methods of sampling and tests for low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE) materials and their compounds. It applies to materials ready for normal use in the form of granules, pellets or powder.
1.2 This standard is intended to be used for identification and characterization of low density polyethylene, linear low density polyethylene, high density polyethylene materials and their compounds on the basis of basic polymer parameters and recommended end uses.
1.3 Though this standard indicates the major end use(s), it does not impose any restriction, however it is no way guarantee the suitability of a particular grade under particular processing and end use conditions.
1.4 This standard is applicable to all polyethylene homopolymers and to copolymers of ethylene having a content of other 1-olefinic monomers of less than 50 percent (mass fraction) and a content of non-olefinic monomers with functional groups up to a maximum of 3 percent (mass fraction).
1.5 This standard does not apply to masterbatches and PE-UHMW (Ultra high molecular weight polyethylene).
