3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
3.1 approved body
organization or manufacturer, operating an approved full quality assurance system to undertake testing of safety components
3.2 safety component
component provided 1 ) to fulfil a safety function when in use
3.3 type examination certificate
document issued by an approved body carrying out a type-examination in which it certifies that the product example under consideration complies with the provisions applicable to it
4 List of significant hazards
This clause contains all the significant hazards, hazardous situations and events, as far as they are dealt with in this standard, identified by risk assessment as significant for this type of machinery and which require action to eliminate or reduce the risk (see Table 1).
5 Design rules, calculations, examinations and tests
5.1 General provisions for type examinations of safety components
5.1.1 Object and extent of the tests
The safety component/device is submitted to a test procedure to verify that insofar as construction and operation are concerned, it conforms to the requirements imposed by this standard. It shall be checked in particular that the mechanical, electrical and electronic components of the device are properly rated and that in the course of time the device does not lose its effectiveness, particularly through wear or aging. If the safety component is needed to satisfy particular requirements (waterproof, dust proof or explosion proof construction) supplementary examinations and/or tests under appropriate criteria shall be made.
5.1.2 General provisions
5.1.2.1 For the purposes of this standard it is assumed that the laboratory undertakes both the testing and the certification as an approved body. An approved body may be that of a manufacturer operating an approved full quality assurance system. In certain cases the test laboratory and the body approved for the issue of type examination certificates may be separate. In these cases the administrative procedures may differ from those described in this standard.BS EN 81-50 pdf download.
