Overview

EN ISO 17491-3:2008 (CEN / ISO) specifies a standardized jet test method to determine the resistance of chemical protective clothing to penetration by a forceful jet of liquid. It applies to Type 3 protective clothing with liquid‑tight connections between garment parts and between the garment and other personal protective equipment. The test is a repeatable pass/fail method that inspects inward leakage using a dyed water jet and an absorbent undergarment; it does not address chemical permeation of materials (that is covered by other standards).

Key Topics and Requirements

• Scope: Suitability for Type 3 liquid-tight clothing and assemblies; excludes permeation testing.
• Test principle: A water jet containing a fluorescent or visible dye is projected at a human test subject wearing the protective suit and an absorbent overall. Visual inspection identifies penetration points.
• Test liquid: Water at (20 ± 2) °C with a dye (e.g., methyl blue), a surfactant (e.g., Genapol LRO / sodium lauryl ether sulphate) and, if required, a dye stabilizer (e.g., citric acid). Required surface tension: (30 ± 5) × 10−3 N/m.
• Calibration stain: A calibrated stain produced on every absorbent overall (dispense (25 ± 5) µl from 5.0 ± 0.5 cm) to establish a reference; minimum stain area 1 cm2 for pass/fail comparison.
• Absorbent overall: One‑piece garment with hood; material must be homogeneous so absorption spots vary less than 10% from the mean for a given liquid volume.
• Nozzle and pressure: Specific nozzle geometry (opening ~4 × 4 mm) and pressure measurement are specified; pressure gauge reading at (150 ± 15) kPa at the nozzle and pump capable of delivering ≥400 kPa.
• Test subjects and safety: Human subjects must fit the suit size range; tests can be hazardous (eyes, face, body) and national safety rules and precautions apply.
• Result type: Pass/fail evaluation based on presence/size of stains on the absorbent overall and inspection of inner suit surfaces.

Applications and Users

• Organizations testing and certifying chemical protective clothing, especially Type 3 suits intended for high‑pressure liquid exposure (jets and splashes).
• Manufacturers validating garment seam and connection integrity, designers of liquid‑tight interfaces (suits, glove/hood connections), PPE test laboratories and conformity assessment bodies.
• Occupational safety professionals specifying PPE for industries where forceful liquid projections (hose ruptures, spray guns, accidental ruptures) pose a hazard.

Related Standards

• EN ISO 17491 series: Part 4 (spray test) is directly related. Other parts (e.g., inward/outward leakage tests) are under development.
• Note: Chemical permeation resistance is covered by other dedicated standards and product-specific normative requirements referenced in the product standard.

Relationship between this part of ISO 17491 and the Essential Requirements of EU Directive 89/686/EEC Personal Protective Equipment.4
Relationship between this part of ISO 17491 and the Essential Requirements of EU Directive 89/686/EEC Personal Protective Equipment This part of ISO 17491 has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association to provide one means of conforming to Essential Requirements of the New Approach Directive 89/686/EEC.
Once this part of ISO 17491 is cited in the Official Journal of the European Communities under that Directive and has been implemented as a national standard in at least one Member State, compliance with the normative clauses of this standard, together with the relevant requirements given in the product standards, confers, within the limits of the scope of both standards, a presumption of conformity with the Essential Requirements of Directive 89/686/EEC Personal Protective Equipment, Annex II, Clause 3.10.2.
WARNING — Other requirements and other EU Directives may be applicable to the product(s) falling within the scope of this standard.

ISO 17491-3:2008(E) © ISO 2008 – All rights reserved iii 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 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-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 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 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 or all such patent rights. ISO 17491-3 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 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). This first edition of ISO 17491-3, together with ISO 17491-4, cancels and replaces ISO 17491:2002, Clauses 6 and 7 of which have been technically revised. ISO 17491 consists of the following parts, under the general title Protective clothing — Test methods for clothing providing protection against chemicals: ⎯ Part 3: Determination of resistance to penetration by a jet of liquid (jet test) ⎯ Part 4: Determination of resistance to penetration by a spray of liquid (spray test) The following parts are under development: ⎯ Part 1: Determination of resistance to outward leakage of gases (internal pressure test) ⎯ Part 2: Determination of resistance to inward leakage of aerosols and gases (inward leakage test) SIST EN ISO 17491-3:2008

ISO 17491-3:2008(E) iv © ISO 2008 – All rights reserved Introduction This part of ISO 17491 describes a test method for determining the liquid penetration resistance of chemical protective clothing Type 3 (with liquid-tight connections between different parts of the clothing and, if applicable, between the clothing and other items of personal protective equipment). Such clothing comprises one or more items covering the full surface of the body and is intended to be worn under conditions where there is a risk of exposure to a forceful projection of a liquid chemical. Interlaboratory testing has shown that this test method is a repeatable pass/fail method. Other requirements with regard to this type of clothing and its constituent materials can be found in the corresponding product standard (see Bibliography [2]). A document on the selection, use and maintenance of chemical protective clothing is available (see Bibliography [3]). CAUTION — Some of the procedures specified in this part of ISO 17491 involve the use of processes which could lead to hazardous situations and hence appropriate precautions should be taken.
