22、l standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Internation
23、al organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules
24、given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at leas

They shall be
37、 informed and instructed on the potential hazards of the tests. The human test subjects shall have a medical check-up to prove their medical fitness for completing the test. See also 3.8.NOTE Attention is drawn to the principles of the Declaration of Helsinki (World Medical Association, 1964) as ame
38、nded at Edinburgh 2000.3.3.2 Number and sizes of human test subjectsWhere tests call for the use of human test subjects, unless otherwise specified, six people shall be used, each wearing a suit of a size category suitable for their build.

However, due to the high variability between human test subjects and the difficulty in assessing some subj
43、ective measures, it is permitted that a device does not completely meet the requirements of the following subjective tests1)in a single sample and in no more than one human test subject. In these 1) For the purpose of this clause, “subjective tests” includes all tests that require the participation

45、 3.10.3. If this additional test is still not clearly passed as required in ISO 15027-1:2012 or ISO 15027-2:2012, then the device shall be deemed to have failed, whilst if it is clearly passed by the additional two subjects, the test panel may deem that the device has passed the test overall. 3.4 Fu

After removal from the container, remove the surface oil by w
47、iping. Subject the samples to a hydrostatic test according to ISO 811 with a speed of 10 cm/min until 1 000 mm water head and then carry out a tensile seam strength test according to ISO 13935-2.3.5 Flammability test3.5.1 PrincipleThe test suit is passed over a test pan with burning test fuel to det

49、hich is folded so that the neck part and feet are even, travels freely across the diagonal distance of the test pan.Fill the test pan with water to a depth of 10 mm, followed by enough petrol or n-heptane to make a minimum total depth of 40 mm.Ignite the petrol or n-heptane and allow to burn freely for 30 s.Drape the suit over a suitable hanger, folded at the waist with the front outward. The bottom of the suit shall be (250 20) mm from the top edge of the test pan, see Figure 1. Secure loose parts above the lower part o
