Standard Methods
All tests are conducted in accordance with the standard methods specified in the following, in order of precedence:
a) Standard methods for testing road construction materials (TMH1 and TMH6) and for calibration (TMH2), compiled by the Committee of State Road Authorities (CSRA) and published by the Department of Transport as part of the series Technical Methods for Highways.
b) South African Bureau of Standards specifications, test methods, codes of practice and co-ordinating specifications (abbreviated as SABS, SANS and CKS).
c) British Standards Institute Specifications (abbreviated as BS).
d) The Specifications of the American Society for Testing and Materials (abbreviated as ASTM).
e) The specifications of the American Association of State Highway and Transport Officials (abbreviated as AASHTO).
f) The standard methods of testing of the South African Bitumen and Tar Association (SABITA).
g) In addition to the above standard methods of testing, standard specifications or test methods of other bodies may also be referred to, or test methods may be described where no acceptable standard methods exist.
