  • 4 samples must be taken for testing with a minimum diameter of 50 mm.<\/li>\n
  • The testing apparatus is the CRE type tensile testing machine according to EN 10002-2<\/li>\n
  • The test punch must be made of steel with a minimum hardness of 60 HRC and with the dimensions described in the standard.<\/li>\n
  • The jaws will prevent the specimen from slipping during the test. They must be made up of two flat steel plates at least 10mm thick with a hole in the centre of 20 \u00b1 0.5mm and 4 fastening bolts.<\/li>\n
  • Specimens must be conditioned according to ISO 2231 (temperature 20 \u00b1 2 \u00b0C and a relative humidity of 65 \u00b1 5%)<\/li>\n<\/ul>\n

      \n
    • The specimen must be placed between the two jaws with the outer surface exposed to the punch.<\/li>\n
    • Tighten the bolts to prevent slippage or deterioration of the specimen.<\/li>\n
    • Place the specimen and jaws on the testing machine.<\/li>\n
    • Advance the punch towards the specimen at 100 \u00b1 10mm\/min. If the punch fails to penetrate the specimen after a 25 mm movement, the test is considered completed.<\/li>\n
    • Record for each test the maximum force (N) to drill the specimen.<\/li>\n<\/ul>\n
