This part of ISO 8370 specifies a dynamic method of determining the location of the pitch zone of a single V-belt in a single pulley groove or of a joined V-belt in a multiple pulley which is expressed as an effective line differential be (see figures 1 and 2), or of a single V-belt in a single pulley groove which is expressed as a datum line differential bd (see figure 3). A hexagonal belt can be treated as a single V-belt.

This International Standard specifies the methods of checking the regularity of the grooves and pulleys for V-belts specified in the system based on datum width. The grooved pulleys may be designed for use with classical or narrow V-belts. Inspection parameters and tolerances of grooved pulleys are specified in appropriate International Standards

This International Standard specifies the maximum electrical resistance of antistatic endless synchronous belts and a corresponding laboratory method of measurement. The test is intended to ensure that the belt is sufficiently conductive to dissipate charges of electricity which may form in it in service. The application of this International Standard is limited to cases of dispute about new belts intended for use in an explosive atmosphere, in situations where there is a fire risk, or wherever a static discharge cannot be permitted. The decision is left to national standards or to agreement between interested parties as to whether the test should be carried out on each belt in a batch or on only a percentage of the batch.
