Standard Malaysian Rubber (SMR) Bulletin No. 7 is a compilation of the Rubber Research Institute of Malaysia (RRIM) protocols and RRIM Test Methods that is referred to by SMR Authorised Laboratories in Malaysia. It was first published in 1970 as a technical reference for testing SMR to specifications. The specification appears as SMR Bulletin No. 11 which is the reference document for grading and specifications for raw natural rubber. Since its first publication, SMR Bulletin No. 7 has gone through two revisions in 1973 and 1992 in order to incorporate latest requirements and techniques pertaining to the testing of SMR. The 2018 revised edition addresses certain issues raised by the industry that requires further technical improvement to the test methods, incorporation of automated techniques and advance instrumentation. This edition also reflects the harmonisation of test methods to ISO standards.
