Protective clothing - Electrostatic properties - Part 5: Material performance and design requirements
This European Standard specifies material and design requirements for electrostatic dissipative protective clothing, used as part of a total earthed system, to avoid incendiary discharges. The requirements may not be sufficient in oxygen enriched flammable atmospheres. This European Standard is not applicable for protection against mains voltages.
Schutzkleidung - Elektrostatische Eigenschaften - Teil 5: Leistungsanforderungen an Material und Konstruktionsanforderung
Diese Europäische Norm legt Anforderungen an Materialien und Konstruktion für elektrostatisch ableitfähige Schutzkleidung, einschließlich Hauben und Kappen, die Bestandteil eines vollständig geerdeten Systems zur Vermeidung von zündfähigen Entladungen ist, fest, wo die Mindestzündenergie einer explosionsfähigen Atmosphäre nicht weniger als 0,016 mJ beträgt.
Im Rahmen dieser Europäischen Norm ist ein vollständig geerdetes System definiert als ein System, in dem Personal und andere Leiter über einen Widerstand von weniger als 108 Ω mit der Erde verbunden sind.
Die Anforderungen an Materialien und Konstruktion ergeben nicht zwangsläufig eine angemessene Erdung zusätzlich getragener oder in Kontakt mit der Kleidung stehender Ausrüstung, wie z. B. Atemschutzgeräte. Falls zusätzliche Ausrüstung geerdet werden muss, können unter Umständen weitere Anforderungen außerhalb des Anwendungsbereichs dieser Europäischen Norm erforderlich sein.
Der Anwendungsbereich dieser Norm beinhaltet keine elektrostatisch ableitfähige Schutzhandschuhe oder elektrostatisch ableitfähiges Schuhwerk, welche separate und nicht integrale Bestandteile der Kleidung sind.
In brennbaren Atmosphären, die mit Sauerstoff angereichert sind, ist es möglich, dass die Anforderungen an Materialien und Konstruktion keinen ausreichenden Schutz bieten.
ANMERKUNG Zusätzliche Informationen zu brennbaren Atmosphären, die mit Sauerstoff angereichert sind, können in CEN/CLC/TR 16832:2015 [1] gefunden werden.
Diese Europäische Norm gilt nicht für den Schutz vor Netzspannungen.
Vêtements de protection - Propriétés électrostatiques - Partie 5 : Exigences de performance des matériaux et de conception
La présente Norme européenne spécifie des exigences relatives à la conception et aux matériaux des vêtements de protection de dissipation de charge électrostatique, y compris les capuches et les casquettes, utilisés en tant que partie d'un système complet relié à la terre, pour éviter les décharges incendiaires, lorsque l'énergie minimale d'inflammation d'une atmosphère explosive n'est pas
inférieure à 0,016 mJ.
Dans le contexte de la présente Norme européenne, un système complet relié à la terre est un système dans lequel les personnes et autres conducteurs sont reliés à la terre via une résistance de moins de 108 Ω.
Les exigences qui s'appliquent aux matériaux et à la conception n'impliquent pas que la mise à la terre d'équipements additionnels portés sur les vêtements ou mis en contact avec eux (appareil respiratoire, par exemple) serait adéquate. S'il s'avérait nécessaire de mettre à la terre ce type d'équipement additionnel, il y aurait lieu d'appliquer d'autres exigences, ne relevant pas du domaine d'application de la présente Norme européenne.
Le domaine d'application de la présente norme n'inclut pas les chaussures ni les gants de sécurité de dissipation de charge électrostatique qui sont des éléments distincts ne faisant pas partie intégrante des vêtements.
Il se peut que les exigences relatives aux matériaux et à la conception n'assurent pas une protection suffisante dans les atmosphères inflammables enrichies en oxygène.
NOTE Des informations complémentaires sur les atmosphères inflammables enrichies en oxygène peuvent être consultées dans le CEN/CLC/TR 16832:2015 [1].
La présente Norme européenne n'est pas applicable à la protection contre les risques liés aux différentes tensions électriques.

EN 1149-5:2018 (E) 4 Introduction This European Standard is part of a series of standards for test methods and requirements for electrostatic properties of protective clothing. Different parts are necessary, because of the various fields of application and materials. EN 1149 consists of the following parts, under the general title “Protective clothing – Electrostatic properties”: — Part 1: Test method for measurement of surface resistivity — Part 2: Test method for measurement of the electrical resistance through a material (vertical resistance); — Part 3: Test methods for measurement of charge decay; — Part 4: Garment test (under development); — Part 5: Material performance and design requirements. A complete garment test is under study. As long as such a test is not available, it may not be possible to perform full assessment of the electrostatic properties of protective clothing. This set of standards reflects the current state of knowledge. Further guidance on the EN 1149 series and on the selection, use, care and maintenance of electrostatic dissipative protective clothing is given in CEN/CLC/TR 16832:2015 [1]1).

EN 1149-5:2018 (E) 5 1 Scope This European Standard specifies material and design requirements for electrostatic dissipative protective clothing, including hoods and caps, used as part of a total earthed system, to avoid incendiary discharges, where the minimum ignition energy of an explosive atmosphere is not less than 0,016 mJ. In the context of this European Standard, a total earthed system is one in which personnel and other conductors are connected to earth via a resistance of less than 108
The material and design requirements do not presume adequate earthing of additional equipment worn or carried in contact with clothing, e.g. breathing apparatus, etc. If such additional equipment is required to be earthed, other requirements beyond the scope of this European Standard may be necessary. The scope of this standard does not include electrostatic dissipative protective gloves or footwear that are separate and not integral parts of garments. The material and design requirements may not provide sufficient protection in oxygen enriched flammable atmospheres. NOTE Additional information about oxygen enriched flammable atmospheres can be found in CEN/CLC/TR 16832:2015 [1]. This European Standard is not applicable for protection against mains voltages. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

The requirements specified in 4.2.1 shall be verified by testing garments or materials after cleaning. If the manufacturer’s instructions indicate that cleaning is not allowed, i.e. single-use garments, then testing shall be carried out on new material. Cleaning shall be in line with the manufacturer’s instructions, on the basis of standardized processes. If the number of cleaning cycles is not specified, the tests shall be carried out after five cleaning cycles (a cleaning cycle is one wash and one dry cycle). This shall be reflected in the information supplied by the manufacturer. If the garment can be washed and dry-cleaned, it shall only be washed. If only dry-cleaning is allowed, the garment shall be dry-cleaned in accordance with the manufacturer’s instructions.
