True or False: A belt-conveyor scales test must be repeated after 48 hours regardless of circumstances.

The statement is false because the requirement to repeat a belt-conveyor scales test is not universally mandated every 48 hours under all circumstances. The frequency of testing can depend on several factors, including the stability of the weighing environment, usage patterns, and specific regulatory or operational guidelines established for the scale in use.

In practice, if the scale is functioning consistently and under controlled conditions, it may not be necessary to retest every 48 hours. Some scenarios may require less frequent testing based on the conditions in which the scale operates, such as changes in material types, mechanical issues, or environmental factors that can impact measurement accuracy. Thus, the correct answer reflects the flexibility allowed within the regulations or manufacturer’s recommendations regarding routine testing.
