EN 381-10:2002 (E)3ForewordThis document (EN 381-10:2002) has been prepared by the Technical Committee CEN /TC 162, "Protectiveclothing including hand and arm protection 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of an identical text orby endorsement, at the latest by April 2003, and conflicting national standards shall be withdrawn at the latest byApril 2003.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and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.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, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain,Sweden, Switzerland and the United Kingdom.



EN 381-10:2002 (E)4IntroductionThis European Standard forms part of a series concerned with personal protective equipment designed to protectagainst the risks arising from the use of hand-held chainsaws.Accidents occur due to a number of complex reasons, but a common factor is incorrect use of the chainsaw. Theimportance of correct training and proper use of a chainsaw in preventing accidents cannot be underestimated.In some countries chainsaw users adopt working practices, which together with training makes the use of chainsawprotective upper body protectors unnecessary. These usually include the instruction to hold the chainsaw with bothhands and to use the chain brake if it becomes necessary to stop cutting. It is often found that for ergonomic,reasons it is impractical to protect the upper body.All parts of the upper body have been shown to be at risk when using a chainsaw.In this European Standard, specifications for the protective coverage and performance of the upper body protectorsare given. No personal protective equipment can ensure a 100% protection against cutting from a hand-heldchainsaw.Nevertheless, experience has shown that it is possible to design personal protective equipment, that offers a certaindegree of protection.Different functional principles may be applied in order to give protection.These include:a) chain slipping: on contact the chain does not cut the materialb) clogging: fibres are drawn with the chain into the drive sprocket and block chain movementc) chain braking: fibres have a high resistance to cutting and absorb rotational energy, thereby reducing the chainspeed.Often more than one principle is applied in chainsaw protective clothing. Upper body protectors meeting thisstandard are meant to be used by users working off the ground and where risk assessment shows that there is asignificant risk to be cut by the moving chain on the upper part of the body such as when working from a sky lift andcarrying out tree surgery.1 ScopeThis European Standard, part 10, specifies the procedures for sampling and pre-treatment of upper body protectorsintended to provide protection against cutting by hand-held chainsaws, the measurement of the protectivecoverage, the apparatus and test methods for assessing resistance to cutting, and the practical performance testfor evaluating ergonomic properties in relation to part 11 of this standard2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

(ISO 3175:1995)EN ISO 6330:2000, Textiles — Domestic washing and drying procedures for textile testing (ISO 6330: 2000)EN ISO 13934-2:1999, Textiles – Tensile properties of fabrics – Part 2: Determination of maximum force using thegrab method (ISO 13934-2:1999)EN 31092:1993, Textiles — Determination of physiological properties — Measurement of thermal and water-vapourresistance under steady-state conditions (sweating guarded — hotplate test) (ISO 11092:1993)3 Terms and definitionsFor the purposes of this European Standard, the following terms and definitions apply:3.1front (of an upper body protector)part of a garment covering the forward 50% of the upper body circumference.3.2rear (of an upper body protector)part of a garment covering the rear 50% of the upper body circumference.NOTEDepending upon design and construction, and due to many layers of protective material, it may be difficult toestablish the division between the front and the rear of an upper body protector. It is nevertheless of great importance toestablish this before pre-treatment and testing.3.3protective materialmaterial which is designed to protect the wearer against the cutting effect of a hand-held chainsaw. This protectivematerial may include the cloth of the garment.3.4unit of protective materialcut out piece or panel of protective material consisting of all the fabric or other layers that constitute the protectivematerial that go into the construction of a garment. A unit has no seams or joins within it. Units may be joinedtogether to provide the complete protective coverage required, before insertion and attachment to garments, butsuch units retain their individuality for testing purposes.4 Test methods4.1GeneralMeasuring instruments unless otherwise specified shall be accurate to ± 2% of the pass/fail level of thecharacteristic being measured.For each of the required sequences of measurements performed in accordance with this standard a correspondingestimate of the uncertainty of the final result shall be determined. This uncertainty (Um) shall be given in the testreport in the form Um = ± X. It shall be used in determining whether a "Pass" performance has been achieved. If



EN 381-10:2002 (E)6the final result minus Um is below the pass level when the requirement that a certain value shall be exceeded, thesample shall be deemed to have failed.4.2Number of test specimensA set of test specimens shall be supplied that is sufficient to complete all the tests. Note that if two types of pre-treatments are specified, the testing and the numbers of test specimens is effectively doubled and two sets arerequired. Test specimens which have been used to assess dimensional stability and protective coverage may beused for cut-testing if it has not been necessary to cut them up for these measurements.The number of garments required for cut testing depends on the number of units of protective material presentwithin them and whether there are any joins or seams between different protective material units such as betweenthe body and the sleeve. Only one test cut shall be carried out on each unit of protective material. Therefore atleast three garments are required for cut testing if the design includes a fastening down the centre front of thegarment, but no seams between the protective material on the body and in the sleeve. For a design incorporatingonly one unit of protective material, six garments are required for cut testing.4.3Sizes of test specimensWhenever possible test specimens shall be of a size to fit users with chest girths of 108 to 112 cm.5 Pre-treatmentExcept in the specific cases detailed below, all the test specimens shall be washed and dried five times beforetesting.Test specimens shall be washed according to EN ISO 6330:2000, procedure 2 A. After each wash cycle the testspecimen shall be dried according to EN ISO 6330:2000, procedure E (temperature not to exceed 70 C). If theupper body protectors are marked as unsuitable for tumble-drying, the test specimens shall be line-dried after eachwash cycle according to EN ISO 6330:2000, procedure A.Exceptions and additions to this treatment shall be made in the following cases:a) Where the upper body protectors are marked as unsuitable for washing, but suitable for dry-cleaning.In such cases, the test specimens shall be dry-cleaned five times before testing.
In principle the dry-cleaning shallbe performed in accordance with the conditions described in 9.1 "Process for normal materials" of ENISO 3175:1995 i. e. using conditioned test specimens, perchlorethylene with surfactant, addition of emulsifiedwater, cleaning for 15 min at (30 ± 3) C, draining and extracting, rinsing for 5 min with pure solvent, and drainingand final extraction, followed by tumble drying with an outlet temperature not exceeding 60 C. No restorativefinishing procedure shall be applied.Where the test specimens are marked as suitable for both washing and dry-cleaning.One set of test specimens shall be washed and dried five times and one set of test specimens shall be dry cleanedfive times.b) Where the manufacturer specifies different washing or cleaning procedures these shall be used in preferenceto those above.6 Testing for dimensional changeOne upper body protector shall be tested by each pre-treatment applicable.It shall be subjected to five pre-treatment cycles according to clause 5 of this standard.



EN 381-10:2002 (E)7After the completion of each cycle, the upper body protectors shall be reshaped by hand, but not reshaped byironing.The dimensions of the protective material coverage shall be measured before the first pre-treatment cycle and oncompletion of last cycle of the pre-treatment procedure.
