Electrical apparatus for the detection and measurement of oxygen - Performance requirements and test methods

Electrical apparatus for the detection and measurement of oxygen - Performance requirements and test methods

This European Standard specifies performance requirements and test methods for portable, transportable and fixed electrical apparatus for the measurement of the oxygen concentration in gas mixtures indicating up to 25 % (v/v). This European Standard applies to apparatus intended for commercial and industrial safety applications, including integral sampling systems of aspirated apparatus. In the case of inert gas purging, this European Standard applies also to apparatus with an oxygen measuring function for explosion protection. It does not apply to external sampling systems, nor laboratory, scientific or medical equipment nor those which are used exclusively for process control. NOTE: The most commonly used oxygen sensors in commercial equipment for industrial application are: paramagnetic sensors; electrochemical sensors (aqueous and solid electrolytes)

1 Scope and object This clause of Part 1 is applicable, except as follows: 1.1.1 Equipment included in scope Replacement: Replace the second paragraph by the following: This Part 2 of IEC 61010 specifies particular safety requirements for the following types a) to c) of electrical equipment and their accessories, wherever they are intended to be used, whenever that equipment incorporates REFRIGERATING SYSTEMS as an integral part of, or separate from, the equipment and the equipment is in direct control of the REFRIGERATING SYSTEM. This document details all the requirements when up to 150 g of FLAMMABLE REFRIGERANT are used per stage of a REFRIGERATING SYSTEM. Additional requirements beyond the current scope of this document apply if a REFRIGERANT charge of FLAMMABLE REFRIGERANT exceeds this amount. Addition: Add the following text after the last paragraph: NOTE 101 Examples for REFRIGERATING EQUIPMENT include, but are not limited to, laboratory equipment such as laboratory refrigerators, freezers, refrigerated display cabinets. It is possible that all or part of the equipment falls within the scope of one or more other Part 2 standards of IEC 61010 as well as within the scope of this standard. In that case, the requirements of those other Part 2 standards will also apply. In particular, if equipment is intended to be used as a centrifuge, the requirements of IEC 61010-2-020 apply. However, when the equipment incorporates a refrigerating system and a heating function where the combination of the two introduces additional or more severe HAZARDS than if treated separately, then it is possible that IEC 61010-2-012 is applicable instead of this Part 2-011. See further information in the flow chart (Figure 102) for the selection process and guidance in the Introduction. 1.1.2 Equipment excluded from scope Addition: Add the following new item after item j): or equipment incorporating: aa) a transcritical REFRIGERANT SYSTEM (system that uses CO2) or a system that uses ammonia (NH3) as the REFRIGERANT. 1.2 Object 1.2.1 Aspects included in scope Replacement: Replace the first paragraph by the following: The object of this document is to ensure that the design and methods of construction of REFRIGERATING EQUIPMENT provide adequate protection for OPERATORS, bystanders, trained service personnel, and the surrounding area against the specific HAZARDS that relate to REFRIGERATING SYSTEMS. Addition: Add the following note after the existing note: NOTE 101 A list of HAZARDS typically associated with REFRIGERATING SYSTEMS and REFRIGERANTS is included in Annex BB.
