23、8, Uncontrolled Copy, (c) BSI iv 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 inte
24、rested 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 Electrotechnica
25、l 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 the t
26、echnical 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 rights. I
27、SO shall not be held responsible for identifying any or all such patent rights. ISO 11611 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
28、ISO/TC 94, Personal safety Protective clothing and equipment, Subcommittee SC 13, Protective clothing, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). ISO 11611 cancels and replaces EN 470-1:1995 and EN 470-1:1995/A1:1998, which have been technically
29、 revised to: a) include additional clothing in the scope; b) specify two classes of protective clothing; c) include additional terms and definitions; d) specify ageing due to washing (maximum number of cleaning procedures as indicated by the manufacturer); e) specify additional tests for heat transf
30、er (radiation) and electrical resistance; f) specify requirements for inoccuousness; g) modify requirements for dimensional change on washing to include requirements for knitted fabrics; h) delete test method for the thickness of leather; i) modify requirements for tensile strength and tear strength
31、; j) specify requirements for burst strength and seam strength; k) include test procedure for the flame testing of seams and hemmed edges; l) modify the information to be supplied by the manufacturer; m) specify requirements for care and maintenance; n) include annex for the selection of welders clo
32、thing; o) include annex regarding information on UV radiation hazards; p) include annex for uncertainty of measurement.

33、 for use in welding and allied processes 1 Scope This International Standard specifies minimum basic safety requirements and test methods for protective clothing including hoods, aprons, sleeves and gaiters that are designed to protect the wearers body including head (hoods) and feet (gaiters) and t
34、hat are to be worn during welding and allied processes with comparable risks. For the protection of the wearers head and feet, this International Standard is only applicable to hoods and gaiters. This International Standard does not cover requirements for hand protection. This type of protective clo
35、thing is intended to protect the wearer against spatter (small splashes of molten metal), short contact time with flame, radiant heat from the arc, and minimizes the possibility of electrical shock by short-term, accidental contact with live electrical conductors at voltages up to approximately 100
36、V d.c. in normal conditions of welding. Sweat, soiling or other contaminants can affect the level of protection provided against short-term accidental contact with live electric conductors at these voltages. This International Standard specifies two classes with specific performance requirements (se
37、e Annex A), i.e. Class 1 being the lower level and Class 2 the higher level. Class 1 is protection against less hazardous welding techniques and situations, causing lower levels of spatter and radiant heat. Class 2 is protection against more hazardous welding techniques and situations, causing highe
38、r levels of spatter and radiant heat. Details are given in Table 1 and Annex B. For adequate overall protection against the risks to which welders are likely to be exposed, personal protective equipment (PPE) covered by other standards should additionally be worn to protect the head, face, hands and
39、 feet. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
