International Org anization for Stand rdization ( ISO)

This is Part1 of BS AU2 6 which cov er components for v ehicle braking sy stems

using petroleum b se fluid s

It is intended to is ue other Parts specify ing petroleum b se brake fluid , bo ts,

cups and seals for use in the braking sy stem

for v ehicle braking sy stems using non-petroleum b se fluid s

Term inolog y and conventions The text of the International Stand rd has

be n a prov ed as suita le for publcation as a BritishStand rd without
