3. EN 17348:2022适用范围：

This document specifies requirements for design, construction, testing and marking of hand-held,portable and transportable vacuum cleaners, including their accessories, constructed to Group II,categories 2G or 3G (of explosion groups IIA, IIB, IIB plus hydrogen), and to Group II, categories 2D or 3D(of explosion groups IIIA, IIIB and IIIC), intended for the collection of combustible or non-combustible dusts and flammable or non-flammable liquids in potentially explosive atmospheres. A potentially explosive atmosphere could be generated by the equipment during its intended use.

NOTE 1  The accumulation of 1 mm or more of combustible dust on surfaces in a working area can create an explosive atmosphere (see reference to 1/32 in. of Depth of Dust Accumulation for Guidance for Area Electrical Classification in NFPA 654, 2017 Edition).

This document applies to equipment driven by electric power and by pneumatic power.

This document gives guidelines for dealing with significant hazards, hazardous situations and/or events relevant to vacuum cleaners when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.

Typical applications for the concerned equipment are:

—  collection of dust produced by machinery at the point of generation;

—  general housekeeping around machinery and of working areas; and/or

—  collection of spills;

—  cleaning of equipment during maintenance operations; and/or

—  collection of specific waste.

For the collection of dust in the presence of flammable liquids or vapours, a specific risk assessment is performed if this is part of the vacuum cleaners intended conditions of use and additional precautions beyond what is described in this document can be required.

NOTE 2  The passage of dust through a vacuum cleaner will generate high levels of electrostatic charge which, in most situations, will be a potential source of ignition to a flammable gas or vapour atmosphere.

For the collection of low-conductivity flammable liquids, a specific risk assessment is performed if this is part of the vacuum cleaners intended conditions of use and additional precautions beyond what is described in this document can be required.

NOTE 3  The resulting liquid velocities are likely to be in excess of the limits required to maintain electrostatic charge generation at a non-hazardous level according to CLC/TR 60079-32-1:2018.

This document does not apply to equipment used to collect toxic dusts where there is a health risk if dust passes through the filter elements. This document does not apply to the collection of dusts which have explosive and unstable properties (UN transport class 1, class 4.1 and class 5.2).

NOTE 4  Hazards related to the use of vacuum cleaners for the collection of hazardous dusts are the subject of other standards.

This document applies to vacuum cleaners with an internal dirty air volume of maximum 250 l.

NOTE 5  250 l is the volume above which it is recognized a vacuum cleaner might not be considered as transportable by an operator, and above which additional explosion protections can be required.

The present version of the document does not apply to battery operated equipment.

NOTE 6  Battery operated equipment might be part of the scope of this document in a subsequent version.

This document does not apply to vacuum trucks.

This document applies to vacuum cleaners of canister and back-pack types. This document does not apply to upright vacuum cleaners.

This document does not apply to motorized cleaning head accessories.

NOTE 7  This document does not apply to household appliances which are the subject of other standards.

This document does not apply to applications where the substances are conveyed into a separate receiving container.

This document does not apply to equipment intended for use in underground parts of mines as well as those parts of surface installations of such mines endangered by firedamp and/or combustible dust.

For an easier readability, all types of equipment concerned by this document are referred as a “vacuum cleaner”.

本文件规定了手持式、便携式和可运输真空吸尘器（包括其附件）的设计、构造、测试和标记要求，这些吸尘器按照第二组2G或3G类（爆炸组别IIA、IIB、IIB加氢气）和第二组2D或3D类（爆炸组IIIA、IIIB和IIIC）制造，用于在潜在爆炸性环境中收集可燃或不可燃粉尘以及易燃或不易燃液体。设备在预期使用过程中可能会产生潜在的爆炸性环境。

注1：工作区域表面积聚1毫米或以上的可燃粉尘会产生爆炸性环境（参见NFPA 6542017年版《区域电气分类指南》中1/32英寸的粉尘积聚深度参考）。

本文件适用于电动和气动驱动的设备。

本文件提供了在制造商合理预见的误用条件下按预期使用真空吸尘器时，处理与真空吸尘器相关的重大危险、危险情况和/或事件的指南。

相关设备的典型应用包括：

--在产生点收集机械产生的灰尘；

--机械和工作区域周围的一般内务管理；和/或

--收集泄漏物；

--在维护操作期间清洁设备；和/或

--收集特定废物。

对于在存在易燃液体或蒸汽的情况下收集灰尘，如果这是真空吸尘器预期使用条件的一部分，则需要进行特定的风险评估，并且可能需要采取本文件所述以外的额外预防措施。

注2：灰尘通过真空吸尘器会产生高水平的静电荷，在大多数情况下，这将成为易燃气体或蒸汽环境的潜在点火源。

对于低导电性易燃液体的收集，如果这是真空吸尘器预期使用条件的一部分，则进行特定的风险评估，并且可能需要采取本文件所述以外的额外预防措施。

注3：根据CLC/TR 60079-32-1:2018，产生的液体速度可能超过将静电电荷产生保持在无害水平所需的限值。

本文件不适用于用于收集有毒粉尘的设备，如果粉尘通过过滤器元件，则存在健康风险。本文件不适用于收集具有爆炸性和不稳定特性的粉尘（联合国运输类别1、4.1和5.2）。

注4：与使用真空吸尘器收集有害粉尘有关的危害是其他标准的主题。

本文件适用于内部脏空气量最大为250升的真空吸尘器。

注5 250升是一个体积，超过这个体积，真空吸尘器可能无法被操作员视为可运输的，超过这个容量可能需要额外的防爆措施。

本文件的当前版本不适用于电池供电的设备。

注6：电池供电设备可能是本文件后续版本范围的一部分。

本文件不适用于真空卡车。

本文件适用于罐式和背包式真空吸尘器。本文件不适用于立式真空吸尘器。

本文件不适用于电动清洁头配件。

注7：本文件不适用于其他标准所涉及的家用电器。

本文件不适用于将物质输送到单独接收容器中的应用。

本文件不适用于拟用于矿山地下部分的设备以及受沼气和/或可燃粉尘危害的矿山地面设施部分。

为了便于阅读，本文档中涉及的所有类型的设备都被称为“真空吸尘器”。
