The TCVN 6143-1996 standard specifies the technical requirements and measurement methods for the opacity of unplasticized polyvinyl chloride (PVC) (PVC) pipes. The standard applies to unplasticized PVC pipes for various purposes and is designed to ensure that the light shading performance of the pipe meets the actual application needs. Opacity testing is carried out through a specific Optical inspection method, covering sample preparation, test equipment calibrating and measurement procedures, and requires strict control of test conditions to ensure the accuracy of the results. The standard specifies the minimum requirements for opacity, provides a mass evaluation basis for manufacturers and users, and helps guide production process improvement and product acceptance. It is widely used in the fields of construction, water transportation and Miscellaneous piping engineering.
