2、 revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the requirements and testmethod for snowboards with channel-mounting systems onwhich bindings are

3、attached to the board by means of aremovable insert and screws.1.2 This test method does not apply to snowboards forchildren with a mass less than 25 kg. It contains data for themanufacturer of snowboards, bindings, and retention devicesconcerning dimensions, tests, and other specifications for theb

4、inding mounting area.1.3 For snowboards with fixed inserts, see ISO 10958-2.1.4 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its

5、 use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Apparatus5.1 Retention Strength Test ApparatusUniversal test ma-chine (UTM), with a pull-out device according to Fig. 1,having a minimum load range of 10 kN.5.2 The pullout device should consist of:5.2.1 A rigid steel attachment plate (A) with one hole of6.5-mm diameter,5.2.2 An insert (

11、B) located in the snowboard channel andbolted through the hole of (A),5.2.3 A universal joint (C) that is connected to the attach-ment plate and the clamping device of the test machine, and5.2.4 Asnowboard support (D) with two rollers and span of200 mm between them.6.

16、eads of engagement has beenverified by extensive tests carried out by snowboard manufac-turers. It is recommended that self-locking screws are used.7. Strength Requirements7.1 Retention StrengthWhen tested in accordance withSection 9, the channel in a snowboard shall have a minimumretention strength

17、 of 4500 N for those snowboards with asuggested rider mass of 45 kg or more and a minimumretention strength of 3500 N for those snowboards with asuggested rider mass between 25 and 45 kg.8.

Precision and Bias411.1 The precision of this test method is based on anintralaboratory study of this test method, conducted in 2012.Asingle labora

21、tory participated in this study, testing sevendifferent types of snowboards. Every test result represents anindividual determination. The laboratory reported between fourand fifty replicate test results for each board. Except for the useof only one laboratory, Practice E691 was followed for thedesig

22、n and analysis of the data.11.1.1 Repeatability Limit (r)Two test results obtainedwithin one laboratory shall be judged not equivalent if theydiffer by more than the r value for that product. r is the intervalrepresenting the critical difference between two test results forthe same product, obtained

23、 by the same operator using thesame equipment on the same day in the same laboratory.11.1.1.1 Repeatability limits are listed in Table 1.11.1.2 Reproducibility Limit (R)Two test results obtainedby different laboratories shall be judged not equivalent if theydiffer by more than the R value for that p

24、roduct. R is theinterval representing the critical difference between two testresults for the same product, obtained by different operatorsusing different equipment in different laboratories.11.1.2.1 Reproducibility limits cannot be calculated from asingle laboratorys results.11.1.3 The above terms

25、(repeatability limit and reproduc-ibility limit) are used as specified in Practice E177.11.1.4 Any judgment in accordance with statement 9.1.1would normally have an approximate 95 % probability of beingcorrect, however, the precision statistics obtained in this ILSmust not be treated as exact mathem

26、atical quantities which areapplicable to all circumstances and uses. The limited numberof laboratories reporting replicate results guarantees that therewill be times when differences greater than predicted by theILS results will arise, sometimes with considerably greater orsmaller frequency than the

27、 95 % probability limit would imply.Consider the repeatability limit as a general guide, and theassociated probability of 95 % as only a rough indicator ofwhat can be expected.11.2 BiasAt the time of the study, there was no acceptedreference material suitable for determining the bias for this testme

28、thod, therefore, no statement on bias is being made.11.3 The precision statement was determined through sta-tistical examination of 100 test results, from a singlelaboratory, on seven types of snow boards.12.
