This part of ISO 3601 defines and classifies surface imperfections on O-rings and specifies maximum acceptable limits for these imperfections, and it is also applicable to O-rings to be used in aerospace construction. Gives quality grades and definitions, and the table contains categories of surface imperfections together with schematic illustrations of these imperfections. An annex gives examples of surface imperfections (figures 1 to 8).

Specifies the requirements for one type of textile reinforced hose for use with air and water having a design working pressure from 0.7 to 1.4 MPa, dependent upon the bore size. The hose is designed for use in underground mining applications, where there is a specific requirements for the hose to have antistatic and flame-resistant properties. 3 tables with values of dimensions and physical properties.

Elimination or reduction are important in many applications. Charges can be dissipated by suitable leakage paths. Antistatic properties of an article are also influenced by its electrostatic charging characteristics. Only methods involving such leakage paths are considered. Addition of carbon black to a polymer allows to produce wide range of conductivity. Antistatic properties may also be produced by incorporating ionizable materials into the rubber mix. - Technical revision of the first edition.
