BIS ISI Certification for Pressure Cooker – An Overview

A Pressure Cooker works on a very simple principle; it is used in cooking food under high-pressure steam using water/a water-based cooking liquid in a sealed vessel. It was first invested in the 1600s by Denis Papin. He called his pot the Digester, but it took quite a while before better manufacturing standards & technology could make these high-pressure pots or cookers safe. The construction of a Pressure Cooker must be suitable to ensure easy & safe handling, good performance & reasonable life. The vessel must be built in such a way that no distortion occurs under normal operating conditions. The body & lid should be free of scratches and other surface flaws. In India, domestic pressure cookers are covered under IS 2347:2017, and this Indian Standard specifies the requirements for Pressure Cookers. BIS or Bureau of Indian Standards mandated to get BIS ISI Certification for Pressure Cooker because this certification guarantees a customer that the product is safe & reliable and can be used by a customer without any safety quality issues.
