Checking the quality and suitability of raw material and selection of material.

   Monitoring of production i.e. process control.

   Assessment of final product, whether the quality is acceptable or not, (how will be the yarn performance in weaving? etc).

   Investigation of faulty materials (analysis of customer complaint, identification of fault in machine etc.).

   Product development and research.

   Specification testing: Specifications are formed and the materials are tested to prove whether they fall within the limits allowed in the specification (e.g. specified by a customer).
