Fluid power systems and components — Cylinders — Nominal pressures
Provides a selection of nominal pressures expressed in bars from 6,3 up to and including 400 bars. The nominal pressure shall be assumed to be "gauge" pressure (i.e. the pressure above the atmospheric value) when no modifier is given. This second edition cancels and replaces the first edition (1975).
Glass — Hydrolytic resistance of glass grains at 98 degrees C — Method of test and classification
The principle, reagents, apparatus and procedure are specified. The resistance is expressed by the volume of acid required for titration of the alkali extracted from the unit mass of glass. For five classes of grain the limit values in the test are listed.
