B Relationship between weathering and the different
   grades of colour fastness
Tables
1 Physical properties of injection moulding compounds
2 Physical properties of extrusion compounds
3 Relationship between softness number and the surface
   temperatures of mill rolls and moulds

Updates the grades available, aligns the test methods with ISO test methods as far as possible and introduces grading by colour fastness.

This British Standard specifies the composition and property requirements for 12 types of general-purpose flexible PVC compounds M1 to M6 used for injection moulding, and E1 to E6 used for moulding and extrusion applications.

NOTE 1 Chlorinated PVC compounds are not included in this standard.

NOTE 2 The titles of the publications referred to in this standard are listed on the inside back cover.
