Fire hazard testing - Test flames. 500 W flame test methods1 Scope This part of IEC 60695 describes a test method consisting of two small scale laboratory test procedures which is intended to compare the burning behaviour of different materials used in electrotechnical products. Vertically oriented bar specimens or horizontally oriented plate test specimens are exposed to a small flame ignition source with a nominal thermal power of 500 W. The test method uses two test specimen configurations to classify

construction and testing of electro-sensitive protective equipment (ESPE) designed specifically to detect persons or parts of persons as part of a safety-related system

Experimental data for several display technologies are presented to demonstrate the need for using a broader range of colours in the test patterns and measuring the display at an image loading level appropriate for the intended application

in Annex A

BS EN 13231-5 concerns work in both plain lines and switches and crossings done with machines according to the BS EN 14033 series and BS EN 15746 series

but it’s been updated to include new concepts such as lifecycle analysis

alteration and dismantling of hoists and sets out the responsibilities of the various parties involved in all these activities

however the values should be within the limits of Tables 2 and 3
