BS EN IEC 60079-26:2024 爆炸性环境 具有分离元件或组合防护等级的设备

1   Scope This part of IEC 60079 specifies requirements for construction, testing and marking for Ex Equipment that contains parts of the equipment with different Equipment Protection Levels (EPLs) and a separation element. This equipment is mounted across a boundary where different EPLs are required, for example between different gas hazardous areas, dust hazardous areas or gas hazardous areas adjacent to dust hazardous areas. EXAMPLE Equipment installed in the wall of storage tanks located in Zone 1 and containing Zone 0 inside. Separation elements are considered for both electrical and non-electrical equipment. If mechanical energy can be transformed into a potential ignition source, additionally an ignition hazard assessment in accordance with ISO 80079‑36 is performed and appropriate measures are undertaken. Suitable measures can be selected from ISO 80079‑37 or IEC TS 60079‑42. This document also specifies requirements for the combination of two Types of Protection, each with EPL Gb, to achieve EPL Ga. Examples are included in 4.2. This document supplements and modifies the general requirements of IEC 60079‑0. Where a requirement of this document conflicts with a requirement of IEC 60079‑0, the requirement of this document takes precedence.

IEC/IEEE 60079-30-1:2015 specifies general and testing requirements for electrical resistance trace heaters for application in explosive atmospheres with the exclusion of those for EPL Ga and Da. This standard covers trace heaters that comprise either factory or field (work-site) assembled units, and which may be series trace heaters, parallel trace heaters, trace heater pads, or trace heater panels that have been assembled and/or terminated in accordance with the manufacturer's instructions. This standard also includes requirements for termination assemblies and control methods used with trace heating systems. The explosive atmospheres referred to in this standard are those defined in IEC 60079-10-1 and IEC 60079-10-2. Annexes D and E outline the application of this standard for those users applying the Division method of area classification. This standard supplements and modifies the general requirements of IEC 60079-0, except as indicated in Table 1 (refer to Clause 1 - Scope of the document). Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirement of this standard takes precedence. This first edition of IEC/IEEE 60079-30-1 cancels and replaces the first edition of IEC 60079-30-1 published in 2007 and constitutes a technical revision. This edition includes the following significant changes, apart from the general revision and updating of the first edition of IEC 60079-30-1 and harmonization with IEEE Std.515, with respect to the previous edition: - the inclusion of a minimum temperature impact test; - the addition of a mechanical procedure in the thermal stability test; - the inclusion of a thermal performance test to replace the thermal safety requirements; - the inclusion of a second procedure utilizing a plate fixture for sheath temperature determination; - the inclusion of an ultraviolet and condensation test; - the revision and significant expansion of documentation requirements; - the addition of Annexes covering requirements for Divisions 1 and 2; - the addition of a table covering the applicability of requirements from IEC 60079-0; - the addition of an Annex covering trace heater product design verification methodology (formerly located in IEC 60079-30-2); - the further harmonization of this edition with several national standards. Please refer to the Foreword of the document for the significance of changes between IEC 60079-30-1, Edition 1.0 (2007) and IEC/IEEE 60079-30-1, Edition 1.0 (2015).

GSO IEC 62990-1:2023 工作场所气氛 第1部分：气体探测器 有毒气体探测器的性能要求

IEC 62990-1:2019 specifies general requirements for design, function and performance, and describes the test methods that apply to portable, transportable, and fixed equipment for the detection and concentration measurement of toxic gases and vapours in workplace atmospheres and other industrial and commercial applications. This document is applicable to continuously sensing equipment whose primary purpose is to provide an indication, alarm and/or other output function the purpose of which is to indicate the presence of a toxic gas or vapour in the atmosphere and in some cases to initiate automatic or manual protective action(s). It is applicable to equipment in which the sensor generates an electrical signal when gas is present. This document applies to two types of equipment: • Type HM (Health Monitoring) ‘occupational exposure’ equipment: For occupational exposure measurement, the performance requirements are focused on uncertainty of measurement of gas concentrations in the region of Occupational Exposure Limit Values (OELV). The upper limit of measurement will be defined by the manufacturer in accordance with 4.2.1. • Type SM (Safety Monitoring) ‘general gas detection’ equipment: For general gas detection applications (e.g. safety warning, leak detection), the performance requirements are focused on alarm signalling. The upper limit of measurement will be defined by the manufacturer according to the intended use of the equipment. In general, the requirements for accuracy will be higher for Type HM equipment than for Type SM equipment. The same equipment may meet the requirements of both Type HM and Type SM. For equipment used for sensing the presence of multiple gases this document applies only to the detection of toxic gas or vapour. This document is not applicable to equipment: - with samplers and concentrators such as sorbents or paper tape having an irreversible indication; - used for the measurement of gases and vapours related to the risk of explosion; - used for the measurement of oxygen; - used only in laboratories for analysis or measurement; - used only for process measurement purposes; - used in the domestic environment; - used in environmental air pollution monitoring; - used for open-path (line of sight) area gas measurement; - used for ventilation control in car parks or tunnels. The contents of the corrigendum of December 2019 have been included in this copy.
