7、 the Produktsicherheitsgesetz (ProdSG) (German Product Safety Act). This document (ISO 11110:2015) has been prepared by Technical Committee ISO/TC 83 “Sports and other recreational facilities and equipment”, Subcommittee SC 4 “Snowsports equipment” (Secretariat: ASI, Austria). The responsible German
8、 body involved in its preparation was DIN-Normenausschuss Sport- und Freizeitgert (DIN Standards Committee Sports Equipment), Working Committee NA 112-03-01 AA Ski- und Snowboardsportgerte. Where this standard has been identified by the Ausschuss fr Produktsicherheit (German Committee for Product Sa
9、fety) 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 test devices for the setting of
10、 the functional unit ski/boot/binding which comply with this standard fulfil the relevant health and safety requirements.

16、 release moments of ski-bindings in retail sales, rental, and other facilities.It specifies requirements for the design accuracy, operation, maintenance, and calibration of the test devices used for determining binding release settings.For other requirements, see appropriate standards (e.g. standard
17、s on electronic measuring devices, safety of electrical apparatus, etc.).This International Standard is to be used in conjunction with ISO 9462 and ISO 8061.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its a

19、ethodsISO 9838, Alpine and touring ski-bindings Test soles for ski-binding tests3 Requirements3.1 General requirements3.1.1 Design3.1.1.1 Setting devices shall be capable of determining the actual release moments of common ski-bindings on the market. They are designed for practical use by retail, re
20、ntal, and other facilities.3.1.1.2 The device shall be capable of completely releasing the boot from the binding.3.1.1.3 In order to avoid the skis elasticity to lead to measurement errors, the clamping of the ski shall be as close as possible to the binding. It shall be possible to apply the releas
21、e load smoothly and without interruption until the maximum release moment has been reached.The release shall be quasi-static such that the total time required shall not be more than 5 s not less than 2 s.The speed at the boot toe or heel shall never exceed 20 mm/s, from the beginning of the release
22、process up to the time when the maximum release value is reached.3.1.1.4 The device shall be capable of indicating the peak release moment after the test is over.DIN ISO 11110:2016-05 5 3.1.1.5 It shall be possible to observe the boot and the binding at all times during the release process.3.1.1.6 T
23、he ski, ski-boot, and ski-binding shall not be damaged by normal use of the test device.3.1.2 Release moments and operating range3.1.2.1 The test device shall indicate release moments in at least forward bending (+ MY) and in twist (+ MZand MZ). The results are given in Newton metres (Nm).Release mo
24、ments shall be in accordance to ISO 9462.3.1.2.2 The manufacturer of the test device shall specify the Recommended Operating Ranges (ROR) of the test device.3.1.2.3 The magnitude of the smallest increment which can normally be estimated shall not exceed 1 Nm for MZand 5 Nm for MYor 5 % of the smalle
25、st value in the ROR, whichever is the greater.3.2 Quantitative requirements3.2.1 AccuracyThe test device shall be of a design such that when tested by the methods of Clause 4 the difference in the results between the test device and the reference device will be as follows.a) The average difference f
26、or all test series shall not exceed for MZ: 10 % or 4 Nm, whichever is the least restrictive, and for MY: 5 % or 10 Nm, whichever is the least restrictive.b) The difference for any individual test series shall not exceed for MZ: 10 % or 4 Nm, whichever is the least restrictive, and for MY: 10 % or 1
27、5 Nm, whichever is the least restrictive.If these requirements are not fulfilled for a test series involving one or several particular bindings, the instructions for use of the test device should describe the appropriate actions: by excluding these bindings from the application field of the device;
28、by giving the amount of correction needed to obtain an accurate measurement, if this is possible by simple means.3.2.2 ReproducibilityThe device shall be of a design such that the reproducibility limit r, when averaged for all series, is not more than 3 %.4 Testing4.1 Test conditionsCarry out the te
29、sts at standard atmosphere 23/50 according to ISO 554 with ordinary tolerances.DIN ISO 11110:2016-05 6 4.2 Test bindingsTake commercial ski-bindings and boots for the tests.If no obvious influence on the release values can be expected from the boots, a variable length sole according to ISO 9838 can
30、be used.Conduct the tests on a group of at least six bindings and the boots by the tests specified by the manufacturer of the test device.Match appropriate bindings to each boot sole and mount according to skis (or simulated skis) in accordance with the binding manufacturers instructions.4.3 Setting
31、 of test bindingsThe release indicator values (Z) and sole lengths (L) shall be as given in Table 1.Table 1 Release indicator values and sole lengthsSole L mmZType C260 2601 1,5Type A300 300 340 3403 10 4 8These settings and sole lengths shall remain unchanged throughout the test series.4.4 Procedur
32、eCarry out the measurement of the release values for each binding and setting as follows:a) On the reference device; Torsion release: 7 measurements for right-hand release and 7 measurements for left-hand release. Forward release: 7 measurements.b) On the test device;After this, measure the release
33、level of the binding with the device to be tested (7 measurements for each direction of release).c) On the reference device.Finally, repeat the initial measurements on the reference device (7 measurements for each direction of release).Test results should not be visible to the operator during a test
34、 series. If a recording device is not used, another person should observe and record each test result.All releases shall be complete so that the binding has to be relocked and closed before each test.Test results may be rejected if a procedural error is detected during a test.For evaluation, delete
35、the highest and lowest test in each series.DIN ISO 11110:2016-05 7 Calculate the mean ( ) and standard deviation (s) of each series of 5 test device results and 10 reference device results by the method below.

38、% for values above 50 Nm inclusive and 0,5 Nm for values below 50 Nm.The measurement error of the release value in forward bending shall be smaller than 1 % for values above 100 Nm inclusive and 2 Nm for values below 100 Nm.The test equipment shall be designed to allow application of pure moments wi
39、thout any extraneous forces during the entire release process.The reference measurements shall also be made with torques even for the evaluation of devices applying release forces.DIN ISO 11110:2016-05 8 5 Instructions for use and maintenanceDetailed, easily understandable instructions for use shall
40、 be provided with the test device.The instructions for use and the relevant supplementary sheets shall indicate those bindings which cannot be adjusted without correction of the values directly read from the measuring instruments (see 4.2). The procedure (e.g. the application of correction tables) s
41、hall be explained in these cases.The manufacturer shall indicate which binding systems cannot be adjusted by means of the test device.The instructions for use shall contain simple methods and intervals which make it possible for the service staff to carry out preseason and random tests for correct f
42、unctioning and accuracy of measurement (e.g. by means of a calibration binding and a test sole).Furthermore, the periods shall be given within which the test device is to be calibrated, and the procedure required by the manufacturer of a firm or institution commissioned by the manufacturer. The maxi
43、mum interval is 2 years.6 Test reportA test report for the description and documentary proof of all calibration processes shall be provided together with the test device. This test report shall include the following information:a) reference to this International Standard, i.e. ISO 11110;b) equipment
