What is checkweighing?

Checkweighing, also known as tolerance weighing, is a key feature in many scales designed for commercial and industrial uses to verify package contents and determine if the weight of a particular product meets the required specifications.  The technique involves the comparison of the weight of the products with predetermined limits set within the scale.

The ash test of plastic samples is used to determine inorganic content. Inorganics have a major influence on the mechanical specification and behaviour of plastics to plastics. The analysis is therefore crucial for quality characteristics. Additional natural products can be added in the production so the nature and quantity are specified and have to be verified as part of Quality Control. On the other hand, components in recycled materials might be unknown and therefore have to be determined additionally. If the moisture content is too high then this is harmful in the processing of plastic granules.
