"Standard: ISO – 1133"
Scope:
Determination of the melt mass-flow rate (MFR) and the melt volume –flow rate (MVR) of thermoplastics
"Standard: ISO – 1183"
Scope:
This method covers to determine the density of P.E Resin by sink and Float method. The Density is a property by which the physical and chemical changes in plastics are detected quickly.
"Standard: ISO-4427-2:2007 (E) Ref: ISO 6259-1/3: 1997 (E) "
Scope:
This method covers to determine the tensile property of thermoplastics pipes, including in particular the following properties.
"Standard: ISO-4427: 1997 (E) Ref: ISO 2505"
Scope:
Method used to determination of longitudinal reversion of low-density, medium density (MDPE) and high-density (HDPE) polyethylene pipes. It also lays down the maximum permissible value of this reversion.
"Standard: ISO-4427-2:2007/ 4437 (E) ISO – 1167"
Scope:
Method for determination of the resistance of thermoplastics pipes to constant internal water pressure at constant temperature. It is applicable to thermoplastics pipes indented for the conveyance of fluids.

OXIDATION INDUCTION TIME (OIT):
"Standard: ISO-11357-6"
Scope:
This Standard specified a method for the determination of oxidation induction time (isothermal OIT) oxidation induction temperature (dynamic OIT) of polymeric material be means of different scanning calorimetry (DCS). It is applicable to polyolefin resins that are in a fully stabilized or compounded form, either as raw material or finished products.
