NEWS ABOUT US PRODUCTS STANDARDS TECHNICAL CONTACT Royde & Tucker Manufacturing / Standards Search STANDARDS Globally there are generally two supra national standards to which hinges and other items of Architectural Hardware can be tested. In Europe and in certain non European countries Euronorm (ENs) are either the accepted classification system or at the very least ENs are recognised and understood. The vast majority of Royde & Tucker hinges are tested to the appropriate European standards, with the resulting certification being drawn from these, potentially several, ENs simultaneously, in addition, in the UK all products required for use on fire, smoke and escape doors must, as a minimum, now be CE marked. ANSI (American National Standards Institute) represent the second globally recognised classification system, which encompasses, amongst other hardware, hinges. Under the ANSI scheme the predominant difference is the prescription of hinge dimensions recommended for certain applications, in addition a different set of testing criteria, testing methodology and classification system are used when testing and certifying hinges. In many instances RT ANSI hinges have been sucessfully tested by UL (Underwriters Laboratories) and are UL listed. To ensure our customers peace of mind and that our products provide a long and trouble free life, all R&T products are fully tested and certificated to comply with the latest regulations. Many R&T products are also Certifire approved. Certifire is a voluntary quality scheme with more stringent standards than those generally required for CE marking.
