适用范围：This British Standard specifies compositional and physical property requirements for four non-black natural rubber compounds designated R40, R50, R60, R70, three non-black natural rubber/zinc oxide compounds designated S40, S50, S60 and five black natural rubber compounds designated T40, T50, T60, T70, T80. These compounds are intended for the manufacture of items in the form of extrusions and items cut from extruded sections, e.g. washers. NOTE 1 The compounds do not necessarily have good electrical insulating properties. NOTE 2 The compounds might not be suitable for use when special properties are required, such as improved ozone or heat resistance, freedom from tarnishing of some metallic components (copper, silver), long term low temperature use or seals in castor oil based fluid systems. The natural rubber compounds specified in this standard do not require 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. There is currently no British Standard for ozone resistant natural rubber compounds.
