In the design of any electrotechnical product, the risk of fire and the potential hazards associated with fire need to be considered. In this respect, the objective of component, circuit and equipment design, as well as the choice of materials, is to reduce to acceptable levels the potential risks of fire even in the event of foreseeable abnormal use, malfunction, or failure. BS EN 60695-1-11, together with its companion, IEC 60695-1-11, provides guidance on how this is to be accomplished.
BS EN 60695-1-11 provides guidance for assessing the fire hazard of electrotechnical products and for the resulting development of fire hazard testing as related directly to harm to people, animals, or property.
BS EN 60695-1-11 on fire testing electrotechnical products standard is useful for:
The primary aims of BS EN 60695-1-11 are to prevent ignition caused by an electrically energised component part and, in the event of ignition, to confine any resulting fire within the bounds of the enclosure of the electrotechnical product. Secondary aims of BS EN 60695-1-11 include the minimisation of any flame spread beyond the product’s enclosure and the minimisation of harmful effects of fire effluents including heat, smoke, and toxic or corrosive combustion products.
BS EN 60695-1-11 outlines a hazard-based process to identify appropriate fire test methods and performance criteria for products. The principles of the methodology are to identify fire events (fire scenarios) that will be associated with the product, to establish how the measurable fire properties of the product are related to the possible occurrence and outcome of those events, and to establish test methods and performance requirements for those properties which will either result in a tolerable fire outcome or eliminate the event altogether.
The sections on elements of fire hazard assessment including ignition sources, fire hazard and fire risk as well as fire hazard tests and the fire hazard assessment process are discussed in thorough detail in BS EN 60695-1-11. Using BS EN 60695-1-11 guidelines you can, assess the fire hazard of electrotechnical products and their ability to cause direct harm to people, animals, and property. BS EN 60695-1-11 enables you to provide your customers with suitable, reliable, and high-quality products.
