Mr. Stokreef had prepared a proposal (R55-12-11) for COP testing of class B. In principle this proposal was to say that at COP a 10 % reduction of the number of cycles could be accepted. Some delegates were slightly positive to this proposal. However Mr. Westphäling argued that according to his experience the S-N-curve had several vertices. One of these often at 1,8 Mc. After just a short discussion this item was postponed to the next meeting when hopefully Mr. Stokreef is present.

Item w12 (Cop testing) (R55_12_11)
Mr. Stokreef repeated the background for the proposal, e.g. the result of the test is very sensitive to the set-up. Many experts at the meeting had a say on this matter. Mr. Svensson argued that the regulations shall be kept as is. At the meeting in January it was said that the successful testing was sometimes a lucky coincidence. By keeping testing COP-testing at the same level as the certification testing those designs that were approved on a lucky coincidence would over time be done away with. If any changes shall be done then a more strict documentation of the test set-up by the certification tests shall be required in the information package for the certification. Mr. Alguëra was open to some changes but was not specific on how to change. Mr. Westphäling argued on the basis of statistics. To get any kind of statistical foundation you need to make at least 6 tests. Mr. Conrads was open to a lower COP test load at 80% to 85%. Mrs. Domagala argued that there should be a combinantion with a static test after the endurance test. The discussion went on for some time but no agreement could be reached.
