Test for Solid Waste and Hazardous Waste
Service Introduction
The final quality of the product depends on the material consistency of different batches of the same product. Consistency comparison test can identify whether the materials used in different batches of products meet the standards to ensure the consistency of different batches of raw materials. At the same time, it can also check whether the quality of raw materials purchased from suppliers meets the product requirements, so as to prevent suppliers from using excessive reclaimed materials or leftover materials.
