For example, if the oxygen index of a material is 21 percent, it means that the material will burn by itself even at room temperature because at room temperature the normal oxygen content is 21 percent. Fire Safety The use of fireretardant/resistant coatings (FRC) is one of the simplest and most efficient methods for building fire protection. It is measured as per IS 10810 Part 59 or IEC 60754 Part 1. Required fields are marked *. (3) Low-halogen, low-smoke flame-retardant PVC insulation, and sheathing: 70; Halogen-free, low-smoke flame-retardant polyolefin insulation and sheathing: 90 and 125 both. Sometimes flame retardant, fire resistance and halogen-free low smoke performance will be integrated in a product, so that the performance of the product is superior, a wider range of application, so the difference between them is sometimes very big and sometimes there is no strict boundary. S. PERSONS UNLESS SUCH SECURITIES ARE REGISTERED UNDER THE SECURITIES ACT, OR AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT IS AVAILABLE. c) Flame retardant tests for cables installed in group. GLI INVESTITORI NON DOVREBBERO SOTTOSCRIVERE ALCUNO STRUMENTO FINANZIARIO SE NON SULLA BASE DELLE INFORMAZIONI CONTENUTE NEL RELATIVO PROSPETTO. (2) Fluoroplastic insulation and sheathing: 220 and 260 two kinds; Fluoroplastic insulation and 105 flame retardant polyvinyl fluoride sheathing: 90 and 125 two kinds. The definition of flame-retardant cable is a cable that will not convey or propagate a flame as defined by the flame-retardant or propagation tests. Manufacturers have to select the proper source for such cable compounds and sometimes need to blend these compounds in their in-house facilities to meet the desired requirement. PE or XLPE are used because of its inherent better electrical/mechanical parameters over PVC e.g. IEC 60287 Current Capacity of Cables - An Introduction. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); W.S. Copyright 2023 Wesco International. For LSZH cables during fire, visibility maintained is at least 80% or smoke density of 20%. Cables used in plenums are required to have a more stringent test than that of the horizontal or vertical flame tests. Now, lots of advancements have taken place and various ingredients are available which if mixed with PVC compound can reduce smoke and toxic gases. Bringing Technological Excellence To Your Doorstep . By writing an electrical note, you will be educating ourusersandat the same time promoting your expertisewithin the engineering community.
