Scope

This outline stipulates the test requirements and test procedures for non-continuous cumulative automatic weighing devices (hereinafter referred to as "cumulative hopper scales").
This outline is applicable to the type evaluation work of national authorized type evaluation laboratories. Other technical institutions or manufacturing enterprises may refer to this outline to conduct corresponding tests.
This outline is applicable to the type evaluation of cumulative hopper scales classified and coded as 12061500.
This outline is not applicable to the following types of cumulative hopper scales:
——Cumulative hopper scales with "dynamic weighing";
——Cumulative hopper scales that obtain the cumulative bulk load by multiplying the mass obtained from multiple weighing cycles by a preset constant load.
