Значение и использование

This practice is used to determine the number of useful impressions obtainable under normal operating conditions of a given typewriter or printer ribbon. It is suitable for service evaluation or research and development. This practice is generally not considered practical for manufacturing control specification acceptance because of the length of time required to obtain results.

Interpretation of the test result is to be made on a comparative basis, not on the basis of absolute values.
