Certifying Agencies
Several different agencies develop standards for intrinsic safety, and evaluate products for compliance with standards. Agencies may be run by governments or may be composed of members from insurance companies, manufacturers, and industries with an interest in safety standards. Certifying agencies allow manufacturers to affix a label or mark to identify that the equipment has been desgined to the relevant product safety standards. Examples of such agencies in North America are the Factory Mutual Research Corporation and the Canadian Standards Association. To facilitate world trade, standards agencies around the world engage in harmonization activity so that intrinsically safe equipment manufactured in one country can be approved for use in another without redundant, expensive, testing and documentation.

Famous quotes containing the words certifying and/or agencies:
“A way of certifying experience, taking photographs is also a way of refusing it—by limiting experience to a search for the photogenic, by converting experience into an image, a souvenir. Travel becomes a strategy for accumulating photographs.”
—Susan Sontag (b. 1933)
“While it is generally agreed that the visible expressions and agencies are necessary instruments, civilization seems to depend far more fundamentally upon the moral and intellectual qualities of human beings—upon the spirit that animates mankind.”
—Mary Ritter Beard (1876–1958)
