Chapter 5 - Approvals
Approvals
Many products have been approved by someone for something. A number of countries have their own ideas on how good a product should be, how it should perform etc. They write their own rules e.g. British Standards, IEC, Canadian Standard Association, and Underwriters Laboratories.
Products are tested against these rules and provided they reach the minimum requirements they can be approved.
Approvals are very specific. Only the products included on the "Approval Certificate" are approved and no more.
Usually proof of approval is shown on the product, either printed on conduits or stamped on connectors, as well as being marked on the pack labels and sometimes on an extra label.
