Repeat the procedure until the roller has traversed the mating tapes five times in each direction, i.e. a total of ten times. Take care that the centre of gravity of the roller does not deviate from the centre
10、 line of the tapes during this operation. Take care that the roller covers the entire width of the mating tapes NOTE: The tapes are turned over to minimize curvature. 8 Test report Report the following information: a) number and date of this European Standard; b) date of the test; c) identification
