5、rland ISO 13232-3:2005/Amd.1:2012(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body

6、interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotech

7、nical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by t

8、he technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent right

17、ampling of frangible components and MATD test helmets 5.1 Initial conformity of production For certification of any new design, material specification, or manufacturing process of any frangible component or MATD helmet and for each of the test methods described in clause 6, 10 unused components or h

18、elmets shall be tested to establish estimates of the samples mean and standard deviation. For example, certification of three different test methods would require 30 components to be tested.

25、, Annex B Add “and helmets” following “skins” in the title of B.2.2 Add the following as a new paragraph to the end of B.2.2: Helmet designs by various manufacturers change periodically, and specific helmet models are not generally available worldwide or over long periods of time. In order to allow

26、researchers worldwide to compare test results, which is the purpose of this part of ISO 13232, a standardized helmet has been specified. This is based on UN/ECE Regulation 22-05 test results including clauses 6.2 and 7.3.6 therein, for helmets with non- protective lower face cover, for the previous

27、ISO 13232-6:2005 standardized Bieffe B12R helmet. Matching the Bieffe B12R test helmet performance, within a specified tolerance, ensures that other test helmet makes and models will produce similar reproducible results for tests done according to ISO 13232-6:2005. Without such a requirement, it is

28、possible that various researchers could reach different conclusions about protective devices, depending on the particular performance characteristics of the test helmet used, even if the same such helmet was used in all tests in a series, as further explained in detail subsequently. Page 71, Annex B

29、 Replace the title “B.3 Sampling of frangible components” by “B.3 Sampling of frangible components and MATD helmet” Add subclause title “B.3.1 frangible components.” Replace “B.3.1 Initial conformity of production (see 5.1)” by “B.3.1.1 Initial conformity of production (see 5.1).” Replace “B.3.2 Sub

30、sequent conformity of production (see 5.2) by “B.3.1.2 Subsequent conformity of production (see 5.2).” Add the following new subclause to B.3: ISO 2012 All rights reserved 3 ISO 13232-3:2005/Amd.1:2012(E) B.3.2 Sampling of MATD helmets (clause 5) The purposes of MATD helmet sampling and measurement

31、are to: allow for performance specification of potentially different MATD helmet models and to ensure that the variability in MATD helmets is controlled to a feasible minimum. B.3.2.1 Initial conformity of production (subclause 5.1) A sample of 10 MATD helmets are specified because this is the appro

32、ximate minimum number needed to establish a usable mean and standard deviation. A relatively tight bound of 5 % for the sample mean for peak resultant head form accelerations is given because these values are crucial in injury assessment. Likewise, a relatively tight specification on the allowable s

33、tandard deviation is given in order to control variation of MATD helmets. A standard deviation less than 7 % of the sample mean is specified for all peak resultant head form accelerations because this reflects the relatively tight bounds that have been achieved with the existing MATD helmet design.

34、Data in Tables B.18 to B.21 for the performance characteristics of the MATD helmet indicate that the MATD helmet meet the criteria. B.3.2.2 Subsequent conformity of production (subclause 5.2) The purpose of the subsequent conformity of production (CoP) tests is for lot checking and quality control o

35、f components, once the MATD helmet has been certified by the manufacturer. Here a compromise between the cost of quality control sampling and the reliability of the sampling process has been reached. For typical past production runs of 30 to 60 helmets, a sample of three helmets represents 5 % to 10

36、 % destructive sampling, which is relatively costly. For a sample of three helmets, assuming a normal distribution and the same mean, it would be expected that one of the MATD helmets would exceed one standard deviation in its properties. Therefore, if none of the MATD helmet peak resultant head for

37、m accelerations deviates by more than two standard deviations (14 %) the lot is considered to be normally distributed and acceptable for impact testing. If one or more of the samples deviates by more than two standard deviations, this exceeds the bounds of a normal distribution, and a larger sample

38、is then used to improve the reliability of the estimate. This involves three more helmets from the same lot. Then, again, if one third of the total test sample deviates by more than two standard deviations from the established means, the lot is considered to exceed the bounds of a normal distributio

39、n and is rejected for full-scale impact testing purposes.
