EN 340:2003 (E)3ForewordThis document (EN 340:2003) has been prepared by CEN /TC 162, "Protective clothing including hand and armprotection and lifejackets", the secretariat of which is held by DIN.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by June 2004, and conflicting national standards shall be withdrawn at the latest byJune 2004.This European Standard supersedes EN 340:1993.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EU Directive(s).For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.The CEN/TC 162 at its 19th meeting on 1998-09-24/25 in Haan, Germany, decided to revise the standard. The workwas allocated to CEN/TC 162/WG 1.The annexes A, B, C and D are informative, annex E is normative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
EN 340:2003 (E)4IntroductionThis European Standard is a reference standard to be called up as appropriate by specific standards. This standardcannot be used alone but only in combination with another standard containing requirements for specific performanceof a product in providing protection. If specific requirements are needed, they should be specified in the appropriatestandard for those products.The revision of the standard EN 340:1993 led to the following main changes in this new standard edition:¾ Basic health and ergonomic requirements including test methods have been added (see clause 4). Mostof the requirements will effect the suppliers of materials to garment manufacturers. Other requirements willbe important for the garment manufacturers to comply with specific product standards.¾ An industrial washing test procedure has been included in clause 5 because this kind of washing isfrequently applied to many types of protective clothing.¾ The size designation system in clause 6 has been improved to take account of the size requirements ofEN 13402 series.¾ A new annex C (informative) has been introduced as a guide to develop specifications for practicalperformance tests in product standards.
EN 340:2003 (E)51 ScopeThis European Standard specifies general performance requirements for ergonomics, innocuousness, sizedesignation, ageing, compatibility and marking of protective clothing and the information to be supplied by themanufacturer with the protective clothing.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications.

EN 340:2003 (E)6NOTEThis statement only refers to laboratory values and does not give indications for the actual time of use.3.2hazardsituation which can be the cause of harm or damage to the health of the human bodyNOTEThere are different general types of hazards, e. g. mechanical hazards, chemical hazards, cold hazards, heat and/orfire hazards, biological agents hazards, radiation hazards.Certain of these types of hazards can, according to circumstances, derive from more specific hazards. Thus, a heathazard can derive from contact heat, radiant heat etc. for each of which there can be separate test methods.Particular garments have been designed to give protection against the hazards encountered in specific types of work.Examples of such garments are aprons that provide protection against hand knives, trousers for use with chainsaws,clothing for protection against chemicals, high visibility clothing and motorcycle rider's protective clothing.3.3riskcombination of the frequency, or probability, of occurrence and the consequence of a specified hazardous eventNOTEThe concept of risk always has two elements: the frequency or probability with which a hazardous event occurs andthe consequences of the hazardous event [6].3.4performance levelnumber that designates a particular category or range of performance by which the results of testing can be gradedNOTEFor further information see annex A.3.5protective clothingclothing including protectors which cover or replace personal clothing, and which is designed to provide protectionagainst one or more hazards3.6waist to waist over the shoulder lengthmaximum length measured from the plane of the waist over the shoulder to the plane of the waistNOTESee also clause 6.4 Basic health and ergonomic requirements4.1 GeneralIn the following paragraphs some basic health and ergonomic requirements are stated that are relevant for
manytypes of protective clothing. For general ergonomic principles to be used in designing and specifying personalprotective equipment see prEN 13921-1[2].Protective clothing shall be designed and manufactured as follows.4.2 InnocuousnessProtective clothing shall not adversely affect the health or hygiene of the user. Protective clothing shall be made ofmaterials such as textiles, leather, rubbers, plastics that have been shown to be chemically suitable. The materialsshall not in the foreseeable conditions of normal use release or degrade to release substances generally known tobe toxic, carcinogenic, mutagenic, allergenic, toxic to reproduction or otherwise harmful. Information claiming thatthe product is innocuous shall be checked.NOTE1 - Information on the classification and identification of harmful substances can be
found e.g. in [7, 8] of theBibliography.
EN 340:2003 (E)7NOTE2 - Guidance on how to consider acceptability of materials in protective clothing is given in informative annex B(flow chart).NOTE3 -
Materials should be selected to minimise the environmental impact to the production and disposal of protectiveclothing.NOTE 4 -
The following list of documents is given for information and as examples of documents to be examined:a) Information supplied by the manufacturer could include a declaration confirming that the product does not contain any substances at levels that are known or suspected to adversely effect user hygiene or health,b) Materials specifications,c) Safety data sheets relating to the materials,d) Information relating to the suitability of the materials for use with food, in medical devices, or other relevantapplications.e) Information relating to toxicological, allergenic, carcinogenic, toxic to reproduction or mutagenic investigations on the materials,f) Information relating to ecotoxicological and other environmental investigations on the materials,The examination should determine whether the claim that the materials are suitable for use in the protectiveclothing or protective equipment is justified. Particular attention has to be paid to the presence of plasticisers,unreacted components, heavy metals, impurities and the chemical identity of pigments and dyes.Materials of protective clothing shall comply with the following requirements:a) The chromium VI content in leather clothing shall comply with the requirements of EN 420.b) All metallic materials
which could come into prolonged contact with the skin (e.g. studs, fittings) shall have anemission of nickel of less than 0,5 µg/cm²
per week. The method of test shall be according to EN 1811.c) The pH value for protective clothing material
shall be greater than 3,5 and less than 9,5. The test method forleather shall be according to EN ISO 4045 and for other materials according to EN 1413.d) The colour fastness to perspiration of protective clothing
material to ensure user hygiene (e.g. no skin staining)shall be determined in accordance with EN ISO 105-A02 and shall be at least grade 4 of the Grey scale for thecolour change of the specimen. The test shall be conducted in accordance with EN ISO 105-E04.e) Azo colorants which release carcinogenic amines listed in prEN 14362-1 shall not be detectable by the methodin that standard.4.3 Design4.3.1The design of protective clothing should facilitate its correct positioning on the user and should ensure thatit remains in place for the foreseeable period of use, taking into account ambient factors, together with themovements and postures that the wearer could adopt during the course of work or other activity. For this purpose,appropriate means, such as adequate adjustment systems or adequate size ranges should be provided so as toenable protective clothing to be adapted to the morphology of the user.4.3.2The design of protective clothing shall ensure that no parts of the body get uncovered by expectedmovements by the wearer (e.g. a jacket should not rise above the waist when the arms are raised) if this is definedin the specific standard. The specific standard for protective clothing shall contain test criteria (e.g. checking thatthe garment can be put on and taken off easily, that arm and knee and bending movements are possible, thatunprotected body areas do not appear during movements, that there is an adequate overlap of jacket and trousers,and that the manufacturers information is adequate to explain the correct usage of the protective clothing (seeannex C).
EN 340:2003 (E)84.3.3Where applicable, protective clothing design should take into account other items of protective clothing orequipment which must be worn to form an overall protective ensemble. The appropriate level of protection shouldbe provided at interface areas between products of the same manufacturer such as in sleeve to glove, trouser tofootwear, and hood and respirator combinations.4.3.4In each specific standard a minimum mechanical property to assess the
strength of a garment shall bedefined.4.3.5 If required in the specific standard the mass shall be given for all sizes of the garment in the informationsupplied by the manufacturer or the marking. The mass shall be given for a garment at 20 °C, 65 % R.H. and innew condition; the mass tolerance or range shall be defined in the specific standard. The mass of one garment sizeshall be measured to check the mass indication in the information of the manufacturer or the marking.NOTE 1A lower mass will not always be beneficial.NOTE 2Protective clothing should be as light as possible taking into account comfort, water vapour resistance, design andprotection level.4.4 Comfort4.4.1Protective clothing should provide users with a level of comfort consistent with the level of protectionagainst hazard which is provided, the ambient conditions, the level of the user’s activity, and the anticipatedduration of use of the protective clothing. Specific product standards shall contain requirements related to thecomfort of particular types of protective clothing and methods for its assessment (e.g. assessment by manualinspection, visual inspection or wearer trial, see annex C). Protective clothing shall not¾ have rough, sharp or hard surfaces that irritate or injure the user;¾ be so tight that blood flow is restricted;¾ be so loose and/or heavy so that it interferes with movements. 4.4.2Where permissible, protective clothing shall be made of materials with low water vapour resistance and/orhigh air permeability and/or shall be sufficiently ventilated to minimise discomfort and thermal stress. In these casestest method(s) and requirement(s) for water vapour resistance of materials
or clothing, air permeability of materialsor ventilation of clothing shall be specified in the specific standard.NOTE 1An international test method is standardised in EN 31092 [1].NOTE 2For other purposes e.g. quality supervision a different reproducible method may be applied to test the water vapourpermeability for use other than classification or testing to meet specified values as laid down in related standards.NOTE 3For further information see prEN 13921-4 [3].4.4.3Protective clothing that imposes significant ergonomic burdens such as heat stress, or is inherentlyuncomfortable because of the need to provide adequate protection, should be accompanied in the informationsupplied by the manufacturer by specific advice or warnings. Specific advice on the appropriate duration forcontinuous use of the clothing in the intended application(s) should be given.5 Ageing5.1 GeneralAgeing can be caused by a single factor or several factors (see 4.8 of prEN 13921-1:2003 [2]). This standard isonly concerned with the detrimental effects of colour alteration, cleaning and dimensional change to the levels ofperformance and legibility of marking (see 5.2 to 5.4).
EN 340:2003 (E)95.2 Colour fastnessIf the specific standard contains requirements for colour fastness, protective clothing shall be tested in accordancewith the relevant part of EN ISO 105 (for example EN ISO 105-B02, colour fastness to artificial light: Xenon arc fadinglamp test).5.3 Dimensional change due to cleaningIf the manufacturer's instructions indicate that garments can be washed or dry cleaned, the test procedure fordimensional change for washing of protective clothing material shall be carried out in accordance with EN 25077 andfor dry cleaning in accordance with EN ISO 3175-1 .Changes in dimension due to cleaning of material for protective clothing shall not exceed ± 3 % in either length orwidth, unless stated otherwise in a specific standard.One sample shall be subjected to 5 washing cycles or dry cleaning cycles according to 5.4 if not otherwise specified.If both washing and dry cleaning are permitted, the sample shall only be washed. Each washing cycle consists ofwashing and drying.5.4 Washing and dry cleaning methodsIf the specific standard contains pre-treatment requirements for checking the detrimental effects of cleaning, the testprocedure shall be as follows, unless stated otherwise in a specific standard.If care labelling or manufacturer's information allows domestic washing or dry cleaning and/or finishing, then theprotective clothing or material shall be washed in accordance with EN ISO 6330 or dry cleaned in accordance with ENISO 3175 -2 and/or finally finished.If industrial washing and/or finishing is allowed, then the protective clothing shall be washed in accordance with ISO15797.If washing is permitted as well as dry cleaning, then the sample shall only be washed.If domestic and industrial washing is permitted, then industrial washing shall be carried out with the specified numberof processes in accordance with ISO 15797.6 Size designationProtective clothing shall be marked with its size based on body dimensions measured in centimetres. Exceptions shallbe specified in detail in the relevant product standards, e.g. Genital protectors for use in sports. Measurementprocedures and the designation of dimensions shall correspond to EN 13402 (see also [4]) if not otherwise specified.The size designation of each garment shall comprise the control dimensions as given in Table 1.Table 1 - Body dimensions for sizing protective clothingNoProtective clothingControl dimensions1jacket, coat, vestchest or bust girth and height2trouserswaist girth and height3coverallchest or bust girth and height4apronswaist or chest or bust girth and height5protectiveequipment
(e.g.knee pads, backprotectors etc.)chest or bust or waist girth or height or body weight or waist to waist overthe shoulder length
EN 340:2003 (E)10The manufacturer can also designate additional measurements, e.g. the arm length, the inside leg length or the hipgirth for women's garments. The value shall correspond to the actual value in centimetres of the user's bodydimensions.On the garment a pictogram according to EN 13402 series shall be used to indicate the size. Height, chest or bustor waist girth, waist to waist over the shoulder length and body weight shall be designated as ranges expressed incentimetres or kilograms. The ranges (maximum interval) for the body dimensions of Table 1 shall be according toprEN 13402-3 or specified in the relevant product standard. The arm length and inside leg length may each begiven a single value.For the measurement of the waist to waist over the shoulder length the tape-measure shall cross the shoulder atthe mid point between the point of the shoulder and the junction of the shoulder to the neck. Anteriorly the tapemeasure shall pass over the chest (or bust) to a point 90 mm lateral to the midline of the body on the plane of thewaist. Posteriorly the tape measure shall follow the shortest distance to a point 90 mm lateral to the midline of thebody. Normal underclothing shall be worn for the measurement. The plane of the waist is the horizontal plane 50mm above the highest points of the hip bones (iliac crests). (The dimension of 50 mm refers to a subject of 1780mm tall and should be scaled pro rata with the height of the actual subject. The distances of 90 mm refer to asubject with a waist girth of 850 mm and should be scaled pro rata with the waist girth of the actual subject.)Examples of size designations are shown in annex D.Product standards or the design criteria used by manufacturers for protective clothing should take the following into account:¾ That if there is a requirement for a zone or zones of protection there should be a specified numericalrelationship between the dimensions of the specific protective materials or constructions in the products, andthe size of user.¾ That the sizing intervals should ensure a good fit is achievable on the majority of users. That there isspecification of the degree of adjustment that is provided to ensure that the fit of the protective clothing isadequate on the range of users each size is intended to fit.¾ That the proportions and the dimensions of the protective clothing should reflect the needs of the users in theenvironments where it is to be used, with the clothing to be worn with it, and performing the normal tasks forwhich it is intended.7
Marking7.1 General markingEach piece of protective clothing shall be marked.The marking shall be:¾ in the official languages of the state of destination for informative wording (e. g. warning phrases)¾ on the product itself or on labels attached to the product;¾ affixed so as to be visible and legible;¾ durable to the appropriate number of cleaning processes.The marking and the pictograms should be large enough to convey immediate understanding and to allow the useof readily legible numbers.
EN 340:2003 (E)11NOTEThe use of numbers not smaller than 2 mm and pictograms not smaller than 10 mm (including the frame) isrecommended. Numbers and pictograms are recommended to be black on white background. Warning against mortal hazardsshould be on the outside of the product.7.2 Specific markingThe marking shall include the following information:a) Name, trade mark or other means of identification of the manufacturer or his authorised representative;b) Designation of the product type, commercial name or code;c) Size designation according to clause 6;d) Number of the specific European Standard (EN.);e) Pictograms and levels of performance, if applicable.As a type designation of a hazard or an application the pictogram shall be used as indicated in the markingrequirements of the specific standard (see annex E with pictogram symbols).Example for clothing for protection against heat and fire:Figure 1 - Example for clothing for protection against heat and fire:For classified requirements the number indicating the level of performance shall be shown beside or below thepictogram. These numbers shall always be in the same fixed sequence as required in the specific standard.NOTEIf these numbers should be shown beside the pictogram start at the right hand side of the pictogram and proceedclockwise.If the manufacturer intends to indicate on the marking that the manufacturer's instructions have to be consulted,then Figure E.2 shall be used.f) care labellingWashing or cleaning instructions shall be given according to EN 23758 if relevant.If there are specific requirements for marking the maximum recommended number of cleaning processes, then themaximum number of proc
