35、of ISO 17491-4:2008/Amd 1:2016 has been approved by CEN as a EN ISO 17491-4:2008/ A1:2016 without any modification.“ DIN EN 17491-4:2016-09 EN ISO 17491-4:2008 + A1:2016 (E) 5 Introduction This part of ISO 17491 describes a test method for determining the spray penetration resistance of chemical pro

36、tective 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) and Type 6 (limited performance protective clothing). Such clothing comprises one or more items covering the full s

37、urface of the body and is intended to be worn under conditions where there is a risk of exposure to a spray of a liquid chemical. Other requirements with regard to this type of clothing and its constituent materials can be found in the respective product standards (see Bibliography 4). Interlaborato

38、ry testing has shown that this test method is a repeatable pass/fail method. A document on the selection, use and maintenance of chemical protective clothing is available (see Bibliography 5). CAUTION Some of the procedures specified in this part of ISO 17491 involve the use of processes which could

39、 lead to hazardous situations and hence appropriate precautions should be taken. DIN EN 17491-4:2016-09 EN ISO 17491-4:2008 + A1:2016 (E) 6 1 Scope This part of ISO 17491 specifies methods for determining the resistance of chemical protective clothing to penetration by sprays of liquid chemicals at

40、two different levels of intensity: a) Method A: low-level spray test. This is applicable to clothing that covers the full body surface and is intended to be worn when there is a potential risk of exposure to small quantities of spray or accidental low-volume splashes of a liquid chemical. b) Method

41、B: high-level spray test. This is applicable to clothing with spray-tight connections between different parts of the clothing and, if applicable, between the clothing and other items of personal protective equipment, which covers the full body surface and which is intended to be worn when there is a

42、 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 references The following referenced documents are indispensable for the application of this docum

43、ent. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO/TR 11610, Protective clothing Vocabulary 3 Terms and definitions For the purposes of this document, the terms and definitions given

44、 in ISO/TR 11610 and the following apply. 3.1 connection assemblage or join 3.2 calibrated stain fluorescent or visible stain, with a defined minimum area, generated by dropping a specified quantity of test liquid on to an absorbent overall NOTE The calibrated stain is used to measure liquid penetra

45、tion during spray and jet testing of chemical protective clothing. 3.3 absorbent overall overall made from an absorbent material, worn under the test suit and intended for collecting liquid penetration during spray and jet testing of chemical protective clothing DIN EN 17491-4:2016-09 EN ISO 17491-4

46、:2008 + A1:2016 (E) 7 4 Principle of test method An aqueous spray, containing a fluorescent or visible dye tracer, is directed under controlled conditions at the chemical protective clothing worn by a human test subject. Inspection of the inside surface of the clothing and the outside surface of the

47、 absorbent overall worn under the test garment allows any points of inward leakage to be identified. 5 Liquid for application in the form of a spray A test liquid containing the following substances shall be used: water at (20 null 2) C; a water-soluble fluorescent or visible dye, e.g. methyl blue (

48、CAS number 28983-56-4); a surfactant, e.g. Genapol LRO liquid (sodium lauryl ether sulphate, CAS number 009004-82-4); a stabilizer for the dye (if needed), e.g. citric acid (CAS number 77-92-9, analytical grade). Prepare the test liquid by dissolving the dye in water. Add the surfactant and the dye

49、stabilizer (if needed) in the appropriate proportions to obtain a solution with following characteristics: a) for method A: a surface tension of (52 null 7,5) null 103N/m; b) for method B: a surface tension of (30 null 5) null 103N/m. NOTE A typical concentrated solution for a high-level spray test can be made by dissolving 4 g methyl blue, 25 ml Genapol LRO liquid and 125 g citric acid in 1 l of tap
