CASfire Technical Co.,Ltd have rich experience to provide ISO 4589-2: Oxygen Index Test to Plastics Material. EN ISO 4589-2: Plastics Determination of burning behaviour by oxygen index â?? Part 2: Ambient- temperature test. EN ISO 4589-2:Oxygen Index Test to Plastics Material - Scope This part of ISO 4589 specifies methods for determining the minimum concentration of oxygen, in admixture with nitrogen, that will support combustion of small vertical test specimens under specified test conditions. The results are defined as oxygen index values. Methods are provided for testing materials that are self-supporting in the form of vertical bars or sheet up to 10,5 mm thick. These methods are suitable for solid, laminated or celluar materials characterized by an apparent density greater than 100 kg/m3. The methods may also be applicable to some cellular materials having an apparent density of less than 100 kg/m3. A method is provided for testing flexible sheet or film materials while supported vertically. For comparative purposes, a procedure is provided for determining whether or not the oxygen index of a material lies above some specified minimum value. Oxygen index results obtained using the methods described in this part of ISO 4589 can provide a sensitive measure of the burning characteristics of materials under certain controlled laboratory conditions, and hence may be useful for quality control purposes. The results obtained are dependent upon the shape, orientation and isolation of the test specimen and the conditions of ignition. For particular materials or applications, it may be necessary or appropriate to specify different test conditions. Results obtained from test specimens of differing thickness or by using different ignition procedures may not be comparable and no correlation with flammability behaviour under other fire conditions is implied. Results obtained in accordance with this part of ISO 4589-2 must not be used to describe or appraise the fire hazard presented by a particular material or shape under actual fire conditions, unless used as one element of a fire risk assessment that takes into account all of the factors pertinent to the assessment of the fire hazard of a particular application for the material.

Product Introduction The electrical integrity of grounding device refers to the grounding device should be between all kinds of electrical equipment grounding device parts and the electrical connectivity between each equipment that is direct current resistance value also known as electrical conductivity. Reliable and effective connection between grounding lead and ground network is the fundamental guarantee of safe operation of power equipment. Ground down lead is electric power equipment and the connection part of the network in the long running process of electric power equipment joint is likely to be affected due to factors such as moisture rust a node or even the phenomenon such as fracture lead to ground down lead and the main grounding network connection resistance increases which cannot meet the requirements of power regulation problems in the operation of the equipment in safe hidden trouble caused serious ground operation. Corrosion and even fracture may occur to the underground grounding pole and its connecting part of the grounding device. Therefore it is necessary to test the electrical integrity of ground equipment regularly. Electric power industry standard DL/T475-2006 "guidelines for the grounding device parameters measurement regulation electric conductivity connectivity should choose special measuring instrument for 1 m instrumentresolution accuracy is not lower than 1.0 on the Richter scale are unlikely.
