Mechanical properties, dimensional requirements, tolerance, surface texture and technical delivery condition for tubes used as barrels for pneumatic fluid power cylinders, the tubes being seamless or welded type in the as-drawn, stress relieved or fully heat treated condition with plain ends and having bores which are specially finished, with or without metal removal.

1.1 This International Standard defines the mechanical properties, dimensional tolerances, surface finishes and technical delivery conditions of the following tubes and bores for pneumatic fluid power cylinders:

• round non-ferrous metallic tubes, seamless or welded type, in the as-drawn stress-relieved or fully heat-treated condition;
• bores, specially finished, with or without metal removal.

1.2 The tubes covered by this International Standard are intended for use as barrels in a wide variety of pneumatic cylinders.

NOTE Brass and aluminium have been considered as a basis in this document but should not be considered the only materials suitable for such applications.

1.3 Annex A specifies the dimensions and tolerances on inside diameters for non-ferrous metallic pneumatic cylinder tubes.

1.4 Annex B provides a recommended method of ordering.
