6、 4 “Snowsports equipment”. The responsible German body involved in its preparation was the Normenausschuss Sport- und Freizeitgert, Working Committee NA 112-03-01 AA Ski- und Snowboardsportgerte. Where this standard has been identified by the Ausschuss fr Produktsicherheit (German Committee for Prod

7、uct Safety) and reference to it has been published in the Gemeinsames Ministerialblatt (German Joint Ministerial Gazette) by the Bundesanstalt fr Arbeitsschutz und Arbeitsmedizin (BAuA) (German Federal Institute for Occupational Safety and Health), it is to be presumed that alpine skis which comply

8、with this standard fulfil the relevant health and safety requirements. Where they comply with the provisions laid down in Section 5 of the Product Safety Act, such products may then be marked with the GS mark (German “safety tested” mark) as awarded to the manufacturer by an authorized “GS organizat

The value of the deformation load, FD, is given by th

25、e point of intersection of this line with the curve (see Figure 3).8.2 Breaking loadThe breaking load, FB, is the maximum load measured during the test, i.e. the maxima of the curve.f) the load-deflection chart together with the deformation and breaking loads;g) any deviation from the procedure of t
