29、mber bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member bodyinterested in a subject for which a technical committee has beenestablished has the right to be represented on that committee. International organizations, government

30、al and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closelywith 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 Directi

31、ves, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standardsadopted 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 c

32、asting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

37、on This part of ISO 17491 describes a test method for determining the spray penetration resistance of chemical protective clothing Type 4 (with spray-tight connections between different parts of the clothing and, if applicable, between the clothing and other items of personal protective equipment) a

38、nd Type 6 (limited performance protective clothing).Such clothing comprises one or more items covering the full surface of the body and is intended to be wornunder conditions where there is a risk of exposure to a spray of a liquid chemical. Other requirements with regard to this type of clothing an

A document on the selection, use and maintenance of chemical protective clothing is available (see Bibliography 5)

42、etermining the resistance of chemical protective clothing to penetration by sprays of liquid chemicals at two different levels of intensity:a) Method A: low-level spray test. This is applicable to clothing that covers the full body surface and isintended to be worn when there is a potential risk ofe

43、xposure to small quantities of spray or accidentallow-volume splashes of a liquid chemical. b) Method B: high-level spraytest. This is applicable to clothingwith spray-tight connections between different parts of the clothing and, if applicable, between the clothing and other items of personalprotec

44、tive equipment, which covers the full body surface and which is intended to be wornwhen there is a risk of exposure to sprayed particles of liquid. This part of ISO 17491 does not address chemical permeation resistance of the materials from which the chemical protective clothing is made. 2 Normative
