Presto Laboratories testing is based on a combination of Indian and international standards such that appliances are subjected to safety, performance, and durability performance checks prior to being marketed. These criteria determine the performance of products at high temperatures, under loads, under electrical loads, and in daily use.
Appliance testing in India is based upon the IS 302 series. It is based on the guidelines of the Bureau of Indian Standards and is in line with IEC 60335. These standards include insulation, leakage current, temperature rise, and electric shock protection.
The compliance of fire and flammability inspections is in accordance with the norms IEC 60695 and Underwriters Laboratory standards, including UL 94. Durability and environmental testing are carried out in accordance with IEC 60068, which is a test that monitors the performance of the appliances in the presence of heat, humidity, and mechanical force.
Energy efficiency testing is in line with the Bureau of Energy Efficiency requirements. In more advanced systems, there are standards such as SAE J2464 that can be employed to determine the safety of batteries.
This is a set of standards that form a comprehensive test setup. They assist manufacturers to satisfy certification requirements and equip products to be safely used in the actual, real conditions.
