29、ternational 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 interested in a subject for which a technical committee h
30、as 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 Electrotechnical Commission (IEC) on all matters of electrotechnical
31、 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 the technical committees are circulated to the member bodi
32、es 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 rights. ISO shall not be held responsible for identifying any
33、or all such patent rights. ISO 12402-7 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 162, Protective clothing including hand and arm protection and lifejackets, in collaboration with Technical Committee ISO/TC 188, Small craft, in accordance with the Agr
34、eement on technical cooperation between ISO and CEN (Vienna Agreement). ISO 12402 consists of the following parts, under the general title Personal flotation devices: Part 1: Lifejackets for seagoing ships Safety requirements Part 2: Lifejackets, performance level 275 Safety requirements Part 3: Lif
35、ejackets, performance level 150 Safety requirements Part 4: Lifejackets, performance level 100 Safety requirements Part 5: Buoyancy aids (level 50) Safety requirements Part 6: Special purpose lifejackets and buoyancy aids Safety requirements and additional test methods Part 7: Materials and componen

37、een prepared to give guidance on the design and application of personal flotation devices (hereafter referred to as PFDs) for persons engaged in activities, whether in relation to their work or their leisure, in or near water. PFDs manufactured, selected, and maintained to this standard should give
38、a reasonable assurance of safety from drowning to a person who is immersed in water. Requirements for lifejackets on large, commercial seagoing ships are regulated by the International Maritime Organization (IMO) under the International Convention for the Safety of Life at Sea (SOLAS). ISO 12402-1 a
39、ddresses lifejackets for seagoing ships. ISO 12402 allows for the buoyancy of a PFD to be provided by a wide variety of materials or designs, some of which may require preparation before entering the water (e.g. inflation of chambers by gas from a cylinder or blown in orally). However, PFDs can be d
40、ivided into the following two main classes: those which provide face up in-water support to the user regardless of physical conditions (lifejackets), and those which require the user to make swimming and other postural movements to position the user with the face out of the water (buoyancy aids). Wi
41、thin these main two classes there are a number of levels of support, types of buoyancy, activation methods for inflatable devices, and auxiliary items (such as location aids), all of which will affect the users probability of survival. Within the different types of buoyancy allowed, inflatable PFDs
42、either provide full buoyancy without any user intervention other than arming (i.e. PFDs inflated by a fully automatic method) or require the user to initiate the inflation. Hybrid PFDs always provide some buoyancy but rely on the same methods as inflatable PFDs to achieve full buoyancy. With inheren
43、tly buoyant PFDs, the user only needs to put the PFD on to achieve the performance of its class. PFDs that do not require intervention (automatically operating PFDs) are suited to activities where persons are likely to enter the water unexpectedly; whereas PFDs requiring intervention (e.g. manually
44、inflated PFDs) are only suitable for use if the user believes there will be sufficient time to produce full buoyancy, or help is close at hand. In every circumstance, the user should ensure that the operation of the PFD is suited to the specific application. The conformity of a PFD to this part of I
45、SO 12402 does not imply that it is suitable for all circumstances. The relative amount of required inspection and maintenance is another factor of paramount importance in the choice and application of specific PFDs. ISO 12402 is intended to serve as a guide to manufacturers, purchasers, and users of
46、 such safety equipment in ensuring that the equipment provides an effective standard of performance in use. Equally essential is the need for the designer to encourage the wearing of the equipment by making it comfortable and attractive for continuous wear on or near water, rather than for it to be
47、stored in a locker for emergency use. Throwable devices and flotation cushions are not covered by this part of ISO 12402. The primary function of a PFD is to support the user in reasonable safety in the water. Within the two classes, alternative attributes make some PFDs better suited to some circum
48、stances than others or make them easier to use and care for than others. Important alternatives allowed by ISO 12402 are the following: to provide higher levels of support (levels 100, 150, or 275) that generally float the user with greater water clearance, enabling the users efforts to be expended
49、in recovery rather than avoiding waves; or to provide lighter or less bulky PFDs (levels 50 to 100); to provide the kinds of flotation (inherently buoyant foam, hybrid, and inflatable) that will accommodate the sometimes conflicting needs of reliability and durability, in-water performance, and continuous wear; BS EN ISO 12402-7:2007+A1:2011EN ISO 12402-7:2007+A1:2011 (E)vi to provide automatically operating (inherently buoyant or automatically inflated) PFDs that float users without any intervention on th
