Protective clothing against chemicals - Test methods and performance classification of chemical protective clothing materials, seams, joins and assemblages
This European Standard specifies the performance classification and test methods for materials used in chemical protective clothing, including gloves and including footwear, when the footwear is an integral part of the clothing, and for seams, joins and assemblages. This is a reference standard to which chemical protective clothing performance standards may refer in whole or in part, but this standard is not exhaustive in the sense that product standards may well require testing according to test method standards which are not included in this standard.
For some of the test method standards for chemical protective clothing referenced in this European Standard, this European Standard modifies the requirements for conditioning, sampling, calculation of test results and reporting. At these instances this standard takes precedence over the referenced test method standards.
NOTE While these performance levels are intended to relate to the usage to which the chemical protective clothing is to be put, it is essential that the chemical protective clothing manufacturer or supplier indicate the intended use of the protective clothing and that the user (specifier) carries out a risk assessment in order to establish the correct performance level for the intended task. This should be included as a mandatory requirement in the information to be supplied by the manufacturer in the product standard.
Schutzkleidung gegen Chemikalien - Prüfverfahren und Leistungseinstufung für Materialien, Nähte, Verbindungen und Verbünde
Diese Europäische Norm legt die Leistungseinstufung und Prüfverfahren für Materialien fest, die in Chemikalienschutzkleidung, einschließlich Handschuhen und Schuhwerk, verwendet werden. Die Handschuhe und das Schuhwerk sollten dieselben Anforderungen an die chemische Schutzwirkung erfüllen wie der Bekleidungsstoff, wenn sie einen integralen Bestandteil der Schutzkleidung darstellen. Die vorliegende Norm ist eine Bezugsnorm, auf die sich Normen, welche die Leistungsfähigkeit von Chemikalienschutzkleidung behandeln, vollständig oder in Teilen beziehen können. Jedoch ist diese Norm nicht erschöpfend in dem Sinne, dass Produktnormen durchaus eine Prüfung in Übereinstimmung mit Prüfverfahrensnormen erfordern können, welche in dieser Norm nicht enthalten sind.
Während es das Ziel dieser Leistungsstufen ist, die Beziehung zur Verwendung herzustellen, bei der die Chemikalienschutzkleidung getragen werden soll, ist es wesentlich, dass der Hersteller oder Lieferant der Schutzkleidung die bestimmungsgemäße Verwendung der Schutzkleidung anzeigt und dass der (die Verwendung bestimmende) Anwender eine Risikobewertung durchführt, um die richtige Leistungsstufe für die vorgesehene Aufgabe festzulegen.
Habillement de protection contre les produits chimiques - Méthodes d'essai et classification de performance des matériaux, coutures, jonctions et assemblages des vêtements de protection chimique
La présente Norme européenne spécifie la classification de la performance et les méthodes d’essai pour les matériaux utilisés dans les vêtements de protection chimique, y compris les gants et les chaussures. Lorsque les gants et les bottes font partie intégrante du vêtement, il convient que les exigences en matière de barrière de protection chimique auxquelles ils sont soumis soient les mêmes pour que pour les étoffes. Il s’agit d’une norme de référence à laquelle les normes de performance des vêtements de protection chimique peuvent faire référence en tout ou partie, mais cette norme n’est pas exhaustive, au sens où les normes de produits peuvent aussi exiger des essais selon des normes de méthodes d’essai qui ne figurent pas dans la présente norme.
Bien que ces niveaux de performance soient destinés à s’appliquer à l’utilisation pour laquelle le vêtement de protection chimique doit être revêtu, il est essentiel que le fabricant ou le fournisseur de ce vêtement de protection chimique précise l'usage pour lequel il est prévu et que l’utilisateur (le spécificateur) procède à une appréciation des risques afin d’établir le niveau de performance correct pour la tâche prévue.
Varovalne obleke pred kemikalijami - Preskusne metode in zahteve za razvrščanje materialov za izdelavo varovalnih oblek, šivanje, spajanje in sestavljanje
Ta evropski standard določa metode za razvrščanje učinkovitosti in preskusne metode za materiale, ki se uporabljajo v oblekah za zaščito pred kemikalijami, vključno z rokavicami in obutvijo, kadar je obutev bistveni del takšne obleke, ter za šivanje, spajanje in sestavljanje. To je referenčni standard, na katerega se lahko v delu ali celoti sklicujejo standardi o učinkovitosti oblek za zaščito pred kemikalijami, vendar ta standard ni izčrpen v smislu, da lahko standardi o izdelkih zahtevajo preskušanje v skladu s standardi o preskusnih metodah, ki niso vključeni v tem standardu.
Za nekatere standarde o preskusnih metodah za obleke za zaščito pred kemikalijami, sklicevane v tem evropskem standardu, ta evropski standard spreminja zahteve za pogojevanje, vzorčenje, izračunavanje preskusnih rezultatov in poročanje. V teh primerih ima ta standard prednost pred sklicevanimi standardi o preskusnih metodah.
OPOMBA: Čeprav naj bi bile te ravni učinkovitosti povezane z izbrano vrsto uporabe oblek za zaščito pred kemikalijami, je bistvenega pomena, da proizvajalec oziroma dobavitelj oblek za zaščito pred kemikalijami nakaže njihovo predvideno uporabo in da uporabnik (določitelj) izvede oceno tveganja z namenom, da se vzpostavi ustrezna raven učinkovitosti za predvideno opravilo. To naj bi bilo vključeno kot obvezna zahteva v informacijah, ki jih pošlje proizvajalec v standardu o izdelku.

EN 14325:2018 (E) 5 1 Scope This European Standard specifies the performance classification and test methods for materials used in chemical protective clothing, including gloves and footwear. The gloves and boots should have the same chemical protective barrier requirements as the fabric when an integral part of the clothing. This is a reference standard to which chemical protective clothing performance standards may refer in whole or in part, but this standard is not exhaustive in the sense that product standards may well require testing according to test method standards which are not included in this standard. While these performance levels are intended to relate to the usage to which the chemical protective clothing is to be put, it is essential that the chemical protective clothing manufacturer or supplier indicate the intended use of the protective clothing and that the user (specifier) carries out a risk assessment in order to establish the correct performance level for the intended task. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

[SOURCE: EN ISO 12947-2:2016] 4 Performance classification of materials 4.1 Determination of property value for performance classification A number of performance classification levels are identified for the various properties of materials to be found in this standard. The value of each property defined in 4.4 to 4.15 and which shall be used for performance classification, shall be determined in accordance with Annex C including the calculation of uncertainty of measurement for all the results. If not specified otherwise within 4.4, 4.5, 4.6, 4.7, 4.9 or within the specific test method itself, a material with different behaviour in the length and cross directions, shall be tested for its performance in both directions. The performance classification shall be based on the results obtained for the direction resulting in the lower performance classification when evaluated according to Annex C. For a material with different surface characteristics, the fabric side that will appear on the outside of the apparel shall be tested for all test methods that are linked to surface performance (i.e. 4.4, 4.5, 4.6, 4.8, 4.11, 4.12, 4.13, 4.14, 4.15,) and the performance classification shall be based on the results for this side. If the chemical protective clothing consists of multiple layers of materials, with or without separable layers, all layers shall be tested together with the chemical protective clothing outer surface being tested for those properties which are linked to surface performance. For materials, which require pre-treatment, the performance classification shall be based on the lowest performance classification obtained on either testing new (not pre-treated) and/or pre-treated materials based on evidence. The performance classification tests shall be performed on the worst case. If insufficient evidence is available to determine whether the test shall be performed as new or pre-treated, the test shall be performed in both conditions. 4.2 Pre-treatment 4.2.1 Pre-treatment by cleaning and disinfection Before each test, all chemical protective clothing material samples, with the exception of limited-use chemical protective clothing, shall undergo pre-treatment by cleaning and disinfection as applicable. If the manufacturer’s instructions indicate that cleaning or disinfection is not allowed, i.e. limited use garments, then testing shall be carried out on new material. Where applicable according to manufacturer’s instruction, the cleaning and disinfection shall be in line with the manufacturer’s instructions, on the basis of standardized procedures. If the number of cleaning and disinfection cycles is not specified, the tests shall be carried out after 5 cycles of pre-treatment, each consisting of one wash cycle, one dry cycle and one disinfection cycle carried out in the sequence as indicated by the manufacturer’s instructions. This shall be reflected in the information supplied by the manufacturer. If the garment can be washed or alternatively dry-cleaned it shall only be washed, dried and disinfected. If only dry-cleaning is allowed, the garment shall only be dry-cleaned and disinfected in accordance with the manufacturer’s instructions. SIST EN 14325:2018
EN 14325:2018 (E) 8 4.2.2 Pre-treatment by abrasion Specimens, which have been pre-treated according to 4.2.1, may also be pre-treated by one of the numbers of abrasion rubs given in Table 1 in accordance with the method described in 4.4.1 and as specified in the product standard or as defined by the manufacturer, whichever is the larger, prior to testing according to 4.11. 4.2.3 Pre-treatment by flexing Specimens, which have been pre-treated according to 4.2.1, may also be pre-treated by one of the numbers of flexing cycles given in Table 2 in accordance with the method described in 4.5.1 and as specified in the product standard or as defined by the manufacturer, whichever is the larger, prior to testing according to 4.11. 4.3 Conditioning Unless otherwise indicated in the product standard, all specimens shall be conditioned by storage at (20 ± 2) °C and (65 ± 5) % relative humidity in accordance with EN ISO 139 for at least 24 h. If applicable, the tests shall be started within 5 min of removing the specimen from the conditioning atmosphere, unless otherwise indicated in the test method standard. Conditioning may be omitted or aligned with the conditions of 4.3 if it can be shown that test results are not affected by the foreseeable changes of temperature and relative humidity. 4.4 Abrasion resistance 4.4.1 General A set of four test specimens of a material sample, where each specimen shall consist of all layers, shall be tested in accordance with EN ISO 12947-2 in the inverted mode, i.e. a test specimen of at least 140 mm diameter placed on the abradant table and an abradant of at least 30 mm diameter mounted in the test piece holder, using abrasive paper specified in Annex B and with an applied downward pressure of 9 kPa. The abrasion resistance of the chemical protective clothing material shall be classified according to the levels of performance given in Table 1, using the highest number of abrasion rubs, determined according to 4.4.2, which do not cause damage to the material. 4.4.2 Determination of the highest number of abrasion rubs which does not cause damage to the material and which shall be used for the performance classification 4.4.2.1 General To determine the level of performance, the leak tightness of each of the four test specimens of a material sample shall be determined after a number of abrasion rubs. An additional sample will be used to determine the leak tightness prior abrasion. There are three methods of leak tightness assessment, the pressure pot, the hydrostatic head and visual inspection. The pressure pot shall be used if possible, but if not possible, the hydrostatic head test is preferred. Alternatively, visual inspection shall be performed, if neither pressure pot nor hydrostatic head test is performed. In this latter case, this shall be reported in the test report and also in the Instructions for Use indicating that the visual inspection is qualitative and does not provide evidence of liquid tightness after abrasion. If the assessment is performed through visual inspection, the maximum classification that can be claimed is a Class 3. Wherever possible the pressure pot method shall be used. SIST EN 14325:2018
EN 14325:2018 (E) 9 Table 1 — Classification of abrasion resistance Class Number of rubs 6 > 2 000 5 > 1000 4 > 400 3 > 100 2 > 40 1 > 10 4.4.2.2 Pressure pot end-point determination To verify if the use of the pressure pot method is possible, unabraded reference specimen shall be clamped in the round test pot apparatus, designed according to the specifications given in Annex E (see Figure E.1), with a diameter appropriate to hold the test specimen, and the pressure in the test pot shall then be reduced by 1 kPa from atmospheric pressure. Preferably the specimen’s exterior face of the fabric shall not be exposed to the pressure, if this is not possible then reverse the face of the fabric prior to reverting to testing using the hydrostatic head. The increase of pressure after 1 min shall be measured and recorded. If the pressure increase for the unabraded specimens is less than 100 Pa, then the pressure pot method is applicable and the leak tightness shall be determined as follows: For each test specimen, the tested area of the abraded specimen is clamped in the round test pot apparatus shown in Figure E.1 and the pressure in the test pot shall then be reduced by 1 kPa. The increase of pressure after 1 min shall be measured and recorded. The difference in the change of pressure in 1 min between a specimen prior to abrasion and the same specimen after abrasion shall be calculated. The maximum resultant value of the difference in the change of pressure in 1 min between abraded and non-abraded shall be determined for the set of specimens. If the maximum resultant value does not exceed 100 Pa in 1 min, a new set of test specimens shall be abraded to a higher level of number of rubs according to the levels of numbers of rubs in Table 1, until the level is reached at which the maximum resultant value exceeds 100 Pa in 1 min. The highest level of number of rubs, at which the sample still passes, shall be used for the performance classification. NOTE The pressure pot method can typically not be applied in case of a too high level of air-permeability and/or breathability of the specimen prior to pre-treatment, e.g. such as flexing or abrasion. 4.4.2.3 Hydrostatic head end-point determination The end point, i.e. the highest number of abrasion rubs which does not cause damage to the material, shall be determined by the measurement of hydrostatic head method according to EN 20811 using a rate of increase in pressure of (0,98 ± 0,05) kPa/min (or 10 cm/min). The hydrostatic head of the specimens of the set of four test specimens prior to any abrasion shall be measured and the av
