Product certification is the process of certifying that a product has passed performance tests and quality assurance tests in order to meet the necessary local, national or international quality standards relevant to a particular market or product set and meets qualification criteria stipulated in contracts, regulations, or specifications (typically called "certification schemes" in the product certification industry). Third party product certification provides confidence that the product is fit for purpose, is manufactured using a defined quality system and links factory production with what was tested by the fire laboratory. Product certification is often required in sensitive industry and marketplace areas where a failure could have serious consequences, such as negatively affecting the health and welfare of the people or person using that product.A product certification scheme is a certification system related to specific products to which the same specific requirements, rules and procedures apply.

The various schemes for third party certification of products vary slightly according to who is providing them but all evaluate most or all of the elements below:

For example, certification is stringent in aerospace applications, since the demands for low weight tend to lead to high stress on components, requiring appropriate metallurgy and accuracy in manufacturing. Other sensitive product area examples include food, pharmaceuticals, healthcare products, dangerous goods, and products that have  emissions such as computers and cellular telephones.Otabu certification limited provide HAACP Certification,ROHS Certification,ISO13485 Certification,CE marking..

Benefits of Product Certification:-

Encourage product quality through upstream control.
Establish flexibility  in production quality concluded continuous surveillance of production process in the factory.
Giving greater confidence in product quality to identified star standards.
Reducing the risk of failure in on-site compliance testing, hence reducing the risk of project delay due to reordering, as well as avoiding wasting time and money.

The process for certification of a product is generally summed up in four step:-
