Domestic Electrical Appiances
The sale of electrical appliances and equipment around the world is conditional to proving that the product is safe. One of simplest ways of demonstrating that the design, construction and performance of the product is safe, is by testing to a safety standard, whether the regulatory regime is mandatory or not.
Whilst safety standards around the world aim to achieve largely the same thing, they vary in the detail from country to country. At Delhi Test House, our fully equipped laboratories and experienced engineers and technicians can carry out product safety testing for many of the Indian standards.
