Product certification is defined as a procedure by which a third party gives written assurance that a product conforms to specified requirement. Product certification involves the issuance of a certificate or mark (or both) to demonstrate that a particular product meets a defined set of requirements for that product. The certification mark is usually found on the product or its packaging and may also appear on a certificate issued by the product certification body.

A product bearing a mark carries a third party guarantee that:

   The product has been produced according to an applicable standard.

   Production has been supervised and controlled

   The product has been tested and inspected

  If customers finds that the product does not meet the declared standard, they can approach

   certification body to resolve their complaint.
