10、SI BS AU 174-2:1985 ii BSI 03-2000 National foreword This Part of BS AU 174 has been prepared under the direction of the Rubber Standards Committee. It is identical with ISO 4925:1978 “Road vehicles Non-petroleum base brake fluid, including the Erratum”, published by the International Organization f
11、or Standardization (ISO). Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is drawn esp
12、ecially to the following. Wherever the words “International Standard” appear, referring to this standard, they should be read as “British Standard”. The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. The
13、 Technical Committee has reviewed the provisions of ISO 301, ISO 1250, ISO 3104, ISO 4926 and ASTM Standards D 91, D 664, D 865, D 1120, D 1123, D 3182, D 3185 and E 298 to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A Brit
14、ish Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Cross-references International StandardCorrespo
