This standard contains requirements for pressure sensitive edges and pressure sensitive bars for use as safety devices and not as actuating devices for normal operational. The standard applies to pressure sensitive edges and pressure sensitive bars used to detect persons or parts of persons who may be exposed to danger such as hazardous moving parts. The purpose of this standard relates primarily to safety and reliability rather than suitability. For the relationship between safety and reliability, see annex D of EN 954-1:1996. This standard specifies requirements for pressure sensitive edges and pressure sensitive bars with and without an external reset facility. This standard is restricted to the functioning of pressure sensitive edges and pressure sensitive bars and does not specify the requirements for their application. However, clause 6 contains requirements for information for use which has to be provided by the manufacturer. A selection procedure is given in annex C. The design notes in annex D give additional guidance regarding the design of pressure sensitive edges and pressure sensitive bars which will give safe and reliable service. The notes in annex E provide general guidance regarding application, while annex G provides guidance on the application of sensors, especially for air-pulse systems. This standard does not specify the dimensions of the pressure sensitive edges or bars in relation to a particular application. The standard does not apply to stopping devices according to EN 60204-1 used only for normal operational, including emergency stopping, of machinery. Additional requirements may be necessary where pressure sensitive edges and pressure sensitive bars are used in locations accessible to elderly or disabled people or children. NOTE It may not be possible to carry out all the tests in this standard for pressure sensitive edges and pressure sensitive bars when they have been designed and built into the machinery by its manufacturer.
