This standard BS 2752:2003 Chloroprene rubber compounds. Specification is classified in these ICS categories:
83.060 Rubber
This British Standard specifies compositional and physical property requirements for five chloroprene rubber compounds of hardness range 40 IRHD to 80 IRHD, designated C40, C50, C60, C70 and C80.
These compounds are intended for the manufacture of items in the form of extrusions, mouldings, moulded or calendered sheet and for items cut or punched from sheet.
NOTE 1 The compounds do not necessarily have good electrical insulating properties.
NOTE 2 The chloroprene rubber compounds specified in this standard are not required to be compounded to be resistant to ozone attack and their resistance to ozone is not tested.
Potential users should seek technical advice if they are unsure as to whether ozone resistance is required for their application. The inherent level of resistance in chloroprene rubber may not be sufficient.
