Further Information Users of this standard are informed that the UK submitted a vote of disapproval on the final voting stage of the dra
5、ft EN ISO due to various technical concerns. The main technical concerns were that the two methods proposed for the measurement of immersed insulation were incomplete and flawed in several respects. In particular, the method involving human subjects omitted the need to measure heat flux, and the equ
6、ation used to compute immersed clo from the heat flux measurements. Additionally, there would be legal and ethical issues in many circumstances in conducting tests in which the body core temperature was allowed to fall below 35?C, as they could under this standard.

These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions
26、of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN ISO 15027-1:2002, Immersion suits Part 1: Constant wear suits, requirements
27、including safety (ISO 15027- 1:2002). EN ISO 15027-2:2002, Immersion suits Part 2: Abandonment suits, requirements including safety (ISO 15027- 2:2002). 3 Testing of the device 3.1 General Requirements, for which no special test methods are given in this standard shall be tested in one of the follow
28、ing ways: a) by tests referred to in EN ISO 15027-1 and EN ISO 15027-2; or b) by measurement; or c) by visual assessment; or d) by functional test. Prior to testing materials and components shall be conditioned for (24 0,1) h under standard atmosphere. 3.2 Sampling Materials and components common to
29、 a range of samples may be presented as one sample of each item to be tested according to test methods given in 4.13 of EN ISO 15027-2:2002, if not specified otherwise by the related test procedure. 3.3 Test subjects 3.3.1 Instruction and selection All test persons shall be familiar with the test pr
30、ocedures and the use of the suit under test. They shall be informed and instructed on the problematic of the tests. The subjects shall have a medical check-up to prove their qualification for the tests. The tests and a reasonable pre-treatment and follow-up shall be witnessed by a physician. All ess
31、ential body functions shall be monitored and reported during the tests. NOTE Attention is drawn to the principles of the Declaration of Helsinki (World Medical Association, 1964) as amended at Edinburgh 2000 and to national rules and regulations such as supervision of the tests by a national ethic c

33、r build. Their body sizes shall be within the heights and weights shown in Table 1, unless otherwise specified. Table 1 Subject sizes Height m Weight kg 1,40 to 1,60 1 person under 60 1 person over 60 over 1,60 to 1,80 1 person under 70 1 person over 70 over 1,80 1 person under 80 1 person over 80 3
34、.3.3 Sex of subjects Not more than 2/3 of the test subjects shall be of any one sex. 3.3.4 Fitness of subjects The persons complying with the criteria of 3.3.1 should be capable of relaxing when in water out of their depth, be able to swim for 20 min and cover a distance of 350 m with the aid of a l
35、ifejacket approved to a relevant EN and, after sufficient rest, board the platform specified in 3.11.6.2. 3.3.5 Dress of subjects Throughout the following tests, unless otherwise specified, the test clothing described in 3.8.1.2 shall be worn by each subject. 3.3.6 Pass/fail criteria All samples sha
36、ll pass all objective tests for the entire device to meet the requirements of EN ISO 15027-1or EN ISO 15027-2. However, due to the high variability between subjects and the difficulty in assessing some subjective measures, it is permitted that a device does not completely meet the requirements of th
37、e following subjective tests in a single example and in no more than in one test subject. In these circumstances, two other subjects within the same weight category and with the same sex, should be subjected to the same test and before the same test panel as at 3.10.3. If this additional test is sti
38、ll not clearly passed as required in EN ISO 15027-1 or EN ISO 15027-2, then the device shall be deemed to have failed, whilst if it is clearly passed, the test panel may deem that the device has passed the test overall. 3.4 Fuel resistance test Place representative samples of all exterior fabrics, t
39、ypical seams, apertures and components in a suitable container and submerge them under a 100 mm head of engine fuel at a temperature of (20 2) ?C for 24 h. After removal from the container, remove the surface oil by wiping. Subject the samples to a hydrostatic test with a 1 000 mm water head and a t
40、ensile seam strength of at least 150 N without damage. Note any damage to the fabric or the seams. 3.5 Flammability test 3.5.1 Principle The test suit is passed over a test pan with burning test fuel. It shall be noted if the suit burns or continues to melt after removal. Licensed Copy: sheffieldun

Test fuel: engine fuel. 3.5.3 Sampling One suit system shall be subjected to the fire test. 3.5.4 Procedure Place the test pan in a draught-free are
42、a so that the suit, which is folded, so that the neck part and feet are even, travels freely across the 578 mm distance of the test pan. Fill the test pan with water to a depth of 10 mm, followed by enough petrol to make a minimum total depth of 40 mm. Ignite the petrol and allow to burn freely for
43、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 of the suit. Then move the suit with a constant speed through the flames for 2
44、 s. The suit shall start and finish the test 2 m away from the closest edge of the test pan. 3.5.5 Evaluation It shall be reported whether the suit sustains burning or continues melting 6 s after being removed from the flames.

46、plywood board, the inside surface of which shall be coated with hard plastic laminate or similar. The bearing of the bin shall be in the centre of the mass and permit the bin to be rotated freely. This rotation can be effected mechanically, either manually or using a motor. 3.6.2 Procedure Place the
47、 test sample in the bin through a flush panel in one of the bins faces, then close and secure it. The bin shall be rotated for a total of 150 revolutions at a steady rate of 6 revolutions per minute. 3.6.3 Evaluation On completion of the rotations, the test sample shall be removed from the bin and e
48、xamined by the panel for functional integrity. If any doubts appear further functional testing shall be performed.
