Recommended test method for assessment of the risk of plasticizer exudation from PVC insulated and sheathed cables

Asnjë informacion i shtuar.

The test method described in this European Standard shows, by the use of accelerated testing, discrete exudation of plasticizer from PVC insulated and sheathed cables. It is for use in circumstances where the manufacturer determines that there may be a specific risk that cannot be assessed only by use of the compatibility test in EN 60811-1-2, 8.1.4. This method is intended as a qualitative test on the completed product and not an individual material test. NOTE 1 Information on the background to use of the test is given in the Introduction. NOTE 2 Although any exudation is most likely to be of plasticizer, other components may also exude and, for the purposes of this standard, are treated equally in this test. NOTE 3 The method has been developed with special reference to PVC/PVC cables. No recommendation is given as to its use with cables based on other insulation and sheathing materials.
