9、. 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. International organizations, governmental and non
10、-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 given in the ISO/IEC Directives, Part
11、 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 least 75 % of the member bodies casting
12、a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO working group
13、 and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 of the mem
14、bers of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, it is reviewed again after a further t
15、hree years, at which time it must either be transformed into an International Standard or be withdrawn. 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 or all such patent right
16、s. ISO/TS 11602-2 was prepared by Technical Committee ISO/TC 21, Equipment for fire protection and fire fighting, Subcommittee SC 2, Manually transportable fire extinguishers. This first edition of ISO/TS 11602-2 cancels and replaces ISO 11602-2:2000, of which it constitutes a technical revision. IS
17、O 11602 consists of the following parts, under the general title Fire protection Portable and wheeled fire extinguishers: Part 1: Selection and installation Technical Specification Part 2: Inspection and maintenance Technical Specification ISO/TS 11602-2:2010(E) ISO 2010 All rights reserved vIntrodu
18、ction This part of ISO 11602 presents a limited number of provisions for the inspection and maintenance of portable and wheeled fire extinguishers, in the knowledge that different countries have particular environments and climates which can affect the size, shape and occupancy of buildings. A count
19、rys specific building configurations can affect the inspection and maintenance of fire extinguishers; therefore, this part of ISO 11602 could be reinforced in respect of fire-extinguishing performance characteristics in the presentation of a general-purpose standard. It is proposed that further inve
20、stigation be undertaken in light of the above for the purposes of a future revision of this part of ISO 11602. TECHNICAL SPECIFICATION ISO/TS 11602-2:2010(E) ISO 2010 All rights reserved 1Fire protection Portable and wheeled fire extinguishers Part 2: Inspection and maintenance 1 Scope This part of
21、ISO 11602 gives requirements for the selection and installation of portable and wheeled fire extinguishers. It is intended as a companion to ISO/TS 11602-1. Fire extinguishers are a first line of defence against fires of limited size. They are needed even if the property is equipped with automatic s
22、prinklers, standpipe and hose, or other fixed protection equipment. This part of ISO 11602 is not applicable to permanently installed systems for fire extinguishment, even though portions of such systems may be portable (such as hose and nozzles attached to a fixed supply of extinguishing media). Ex
23、tinguishers for use on board aircraft, watercraft and vehicles are outside the scope of ISO 11602. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the lates
