Virgin material PVC resin are comprehensively used to product Pipes which consists substantially Unplasticized Polyvinyl Chloride and additives needed to facilitate the manufacturer of the Pipe and production of sound and durable pipe of good surface finish, mechanical strength and opacity under conditions of use. None of these additives shall be used separately or together in quantities sufficient to constitute a toxic organoleptic or microbial growth hazard to impair its chemical and physical or mechanical properties ( in particular longterm mechanical strength and impact strength). The company carefully used the quantity of PVC resin material and other additives, so that there would be no hazarders effect of human. A continuous process is followed by the Quality Control Dept, of the company by sending a sample of PVC Resin to CIPET Haldia, periodical checking to confirm the limit of VCM content and also to know the K-value. Test Reports of PVC Resin are also collected from the manufacturer Reliance Industries Ltd as well as the other components from the respective manufacturers. The management keeps regular vigil about the test Effect on water (the pipes manufactured by the company) undertaken by CI PET Haldia. It is essential to confirm the Pipes shall not have any detrimental effect on the composition of water following through them.
When tested by the method of Indian standards, the quantities of lead, dialkyl tin C4& higher homologues (measured and tin) and any other toxic substances extracted from the internal walls of the Pipes shall not exceed the following concentrations (based on' Guidelines for Drinking Water Recommendations'- WHO Geneva, 1984) in the test solutions: -
