direction of the Rubber Standards Committee in consultation with the Automobile Standards Committee It is identical with ISO 7309: 985 “Road v ehicles — Hydraulic b raking sys tem s — ISO reference p etro leum b ase fluid ”, published by the International Organization for Standardization (ISO) This is Part of BS AU 21 which covers components for vehicle braking systems using petroleum base fluids It is intended to issue other Parts specifying petroleum base brake fluid, boots, cups and seals for use in the braking system The associated British Standard BS AU 74 “Hydraulic non- p etro leum b ase b rake fluids, for road v ehicles b rake sys tem s, using ” specifies similar components for vehicle braking systems using non- petroleum base fluids 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 especially to the following 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 Wherever the words “International Standard” appear, referring to this standard, they should be read as “Part of this British Standard” Cross-references International Standard ISO 2592: 973 C
