40 Laboratory Tests in Sanitaryware

Various tests are being carried out by the laboratory in a sanitary ware production process to ensure the Quality of the Final product. And testing starts from raw material discharge area up to Dispatch. This test are very important to keep the rejection rate low in production as most the problem can be found at the initial stage and eliminated immediately.  Find the below list of tests carried out in sanitary ware lab to ensure the quality.

  1. Clay test (Plastic materials)
  2. Moisture content in clay
