Rubber gaskets are elastomeric or rubber-based sealing elements used to provide a tight seal between two mating surfaces. They are utilized for sealing purposes in a variety of industries and available in a variety of shapes and sizes, including O-rings, flat washers, and custom-shaped gaskets. Because of these gaskets' adaptability, durability, and resistance to a range of chemicals, pressures, and temperatures, they are preferred.
In pressure cookers, rubber gaskets are essential for preserving an airtight seal that permits the accumulation of steam and pressure required for effective cooking. These gaskets, which are usually composed of food-grade rubber or silicone, make sure that no steam escapes during cooking, allowing the cooker to achieve and maintain the necessary pressure levels. By averting leaks and guaranteeing the right cooking conditions within the pot, they enhance the pressure cooker's performance and safety.
Rubber gaskets for pressure cookers are still in high demand due to the rising popularity of pressure cookers for quick and easy food preparation and the necessity for replacements.
Under IS 7466:2023 all rubber gaskets for pressure cookers are required to be part of the ISI Certification Scheme.
The criteria and methods for collecting and testing rubber gaskets used especially in pressure cookers are described in this standard.
Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program.
Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.

Simplified Procedure
This is a much faster process than the standard procedure. After a factory inspection is deemed satisfactory and the initial evaluation establishes that the sample complies with the applicable Indian Standard(s), the license application process is expected to be finished in 30 days.
Step 1: Adapting the Manufacturing Unit to Comply with the Relevant Indian Standard
Step 2: Sample Testing
