EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60695-11-21 test. Describes a small-scale laboratory procedure for determining comparative combustion properties of tubular polymeric materials. A flame is applied to test specimens held in a vertical position supported by a wire or mandrel. After the test flame is extinguished, extinguishing times and burning characteristics are determined.
This test method can be used to compare the combustion properties of tubular polymeric materials. This test method should not be used to compare the combustion characteristics of any wire or cable product or any cable management system. This test method can be used to compare the relative performance of materials, to assist in material selection, for quality control purposes and for quality assurance.
The best method of testing electrotechnical products for fire hazard is to exactly replicate the conditions that occur in practice. In most cases this is not possible. Accordingly, for practical reasons, testing of electrotechnical products for fire hazard is best accomplished by simulating as closely as possible the real effects that occur in practice.
The parts of the electrotechnical equipment, which may be exposed to excessive thermal voltage due to electrical effects and whose failure may impair the safety of the equipment, should not be excessively affected by the heat and fire formed in the equipment.
Parts of insulating material or other flammable materials that could potentially spread flames within the equipment can be ignited by flames produced by a faulty component. Under certain conditions, for example, a fault current flowing through a trace path, overloading of components or parts and bad connections, flames can also occur; such flames may strike nearby combustible parts.
This technical specification should be used to measure and describe the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or evaluate the fire hazard or fire risk of materials, products or materials. installations under real fire conditions. However, the results of this test can be used as elements of a fire risk assessment that takes into account all factors relevant to the fire hazard assessment of a particular end use.
This technical specification may contain hazardous materials, processes and equipment. This technical specification does not purport to address all safety issues associated with its use. It is the responsibility of the user of this technical specification to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
