This International Standard specifies three methods for deter-mining the resistance of the outer cover of hoses to ultra-violet light :
Method 1 : for bore sizes up to and including 25 mm, the test being carried out on the hose itself;
Method 2 : for bore sizes greater than 25 mm, the test being carried out on a test piece from the hose wall;
Method 3 : for bore sizes greater than 25 mm, the test being carried out on a test piece from the hose cover.
Method 1 or 2 should normally be used. Method 3 should be used only if it is not possible to carry out the test in accordance with Method 2.
