N1)DIN ISO 8783:2016-05 5 4 PrincipleEvaluation of ski performance through subjective and comparative rating by co
16、mpetent test personnel based on the test criteria provided, and statistical support by using sufficient individual results with regard to test personnel, terrain conditions and test skis.5 Test conditionsThe test run shall provide terrain on which all skiing manoeuvres can be carried out. The site s
17、hall permit every tester to conduct the same manoeuvres at the same place on the slope.The test shall be carried out in hard and well-prepared snow conditions.Each tester shall test every ski of a predetermined group of skis. Skis belonging to the same category of test skis shall be tested within on
18、e day, provided that snow conditions do not change considerably during the course of the day. If snow conditions do change considerably within the course of the day, the test shall be interrupted and be continued, provided snow conditions are comparable, on the next day.6 Test personnel6.1 Requireme
19、ntsThe test personnel shall be independent, neutral, and discreet, as responsible experts.6.2 Skiing abilityThe skiing ability of personnel shall be such that a representative evaluation of the skis in accordance with the test run is ensured. The physical condition of personnel shall be adequate for
20、 the tasks of the test. The physical condition and the skiing ability should not change significantly during the course of the test. The tester shall be capable and shall be trained to use ski techniques according to the test criteria and also to perform skiing motions treated as single movements.6.
21、3 Assessment abilityThe tester shall be completely informed about all evaluation criteria and about the system rating scale.7 Test committeeTests shall be supervised by a test committee consisting of at least three technical experts and the test supervisor.The test committee shall determine, by majo
22、rity vote, when the conditions are adequate for testing.8 Test skisThe test skis shall be typical of the model to be tested and shall be tested as delivered by the manufacturer. The test skis shall be inspected and if, in the course of the test, retuning is deemed to be necessary, this shall be done
23、 in accordance with manufacturers instructions.The running surfaces shall be cleaned and uniformly waxed in accordance with the snow conditions at the time of the test.DIN ISO 8783:2016-05 6 For each tester, the boot and binding shall be fitted correctly in relation to the mounting point of the ski,
24、 for example by the use of bindings with a movable toe-piece.9 Rating9.1 CriteriaThe criteria to be tested are listed below:a) movement;b) edge grip;c) steering behaviour;d) stability;e) quietness;f) skier friendly/ski character.9.2 ClassificationFor proper comparative rating, it is necessary to use
25、 reference skis. These reference skis shall be used repeatedly by all testers. Test skis are rated by comparison with the performance of the reference skis.To assess the required criteria, a rating scale of five grades should be used:a) very good;b) good;c) satisfactory (no special positive or negat
26、ive characteristics);d) poor;e) very poor.10 PreparationThe test ski shall be tested in an undamaged condition only (free of burrs). When the running surface is damaged considerably, the ski shall be withdrawn from the test for refurbishment of the damaged area.There shall be no tests prior to the o
27、fficial test and nobody shall be allowed to ski on the test skis prior to the official test.11 Additional elements and tuning (binding and damping elements)If a ski model is sold exclusively with such additional attached/mounted elements, this ski model may be tested in its category together with co
28、mparable skis which do not feature this kind of element.If a ski model can be tuned by means of optional elements in order to alter its performance, then it should be possible to test this particular function as well, or it should be possible to conduct a separate test for the ski with the tuning el
29、ements.DIN ISO 8783:2016-05 7 12 Binding and binding systemsThe ski shall be tested with the bindings or binding systems which are recommended by the manufacturer.13 Test reportThe test report shall include at least the following information:a) a reference to this International Standard, i.e. ISO 87
30、83;b) an indication of whether the skis are tested as delivered or whether they have been treated for the test;c) a description of the skis tested and their lengths;d) individual ratings given;e) total scores and standard deviations;f) any significant deviation from the average of the skis and teste
31、rs (e.g. testers weight or height, skis length, width, side cuts).14 Publication of test resultsPublished test results shall provide information on all test and snow conditions.If ski characteristics are described verbally, only clearly defined technical terms should be used.If the publication provi
32、des information in the form of an overall score, the weight of individual ratings and the reasoning for this weighting system shall be explained. All considerations which have led to the overall score shall be published.An appropriate person or body shall take legal responsibility for carrying out tests and publication of the test results.DIN ISO 8783:2016-05 8
