[Replace the scope of this Standard with the following]

This document provides safety related requirements for construction, operation under normal and abnormal conditions and the testing of fuel cell stacks and fuel cell modules. It applies to fuel cell stacks and fuel cell modules with the following electrolyte chemistry:

• alkaline, for e.g. potassium hydroxide;

• polymer electrolyte (including direct methanol fuel cells), for e. g. PEM, AEM (anion exchange membrane);

• acidic, for e.g. phosphoric acid;

• molten carbonate;

• solid oxide;

• aqueous solution of salts.

Fuel cell stacks and fuel cell modules can be provided with or without an enclosure and can be operated at significant pressurization levels or close to ambient pressure.

These requirements can be superseded by other standards for equipment containing fuel cell stacks and fuel cell modules as required for particular applications.

This document does not cover fuel cell road vehicle applications.

This document is not intended to limit or inhibit technological advancement. An appliance employing materials or having forms of construction differing from those detailed in the requirements of this document can be examined and tested according to the purpose of these requirements and, if found to be substantially equivalent, can be considered to comply with this document.

The fuel cell stacks and fuel cell modules are components of a final product or system. The final products or systems that integrate these fuel cell stacks or fuel cell modules will require evaluation according to appropriate end-product safety requirements, such as:

CSA/ANSI FC 1 * CSA C22.2 No. 62282-3-100 for stationary fuel cell power systems; or

ANSI/CSA America FC 3 for portable fuel cell power systems;

Note 1 to entry: A fuel cell module can consist of one or more, but not all, integrated system components.  An assembly which is made up of all the integrated system components of a final product or system is not considered a module. (Figure 1A).

This document covers only up to the DC output of the fuel cell module.

This document does not apply to peripheral devices outside the fuel cell module as illustrated in Figure 1A.

This document does not cover the storage and delivery of fuel and oxidant to the fuel cell module.

This document does not cover fuel cell power systems (“modules” or “battery replacements”) for industrial trucks that are in the scope of UL 2267.

This standard covers the above-noted products that are intended to be installed or used in accordance with:

CSA C22.1, Canadian Electrical Code (CE Code) Part I,

NFPA 70, National Electrical Code (NEC)

Note 2 to entry: Fuel cell stacks and fuel cell modules are components integrated into fuel cell power systems that are then installed per the electrical codes noted above.

NOTE 1 Wastewater is always generated when water is used or consumed. Accordingly, sources of wastewater can be residential, industrial, commercial or
institutional. Collected storm water or (melted) snow can also be considered as wastewater, as it often carries contaminants and pathogens picked up from
air or ground surfaces on its way to a collection system. In certain circumstances, especially in undeveloped areas, sanitary waste is collected in an
undiluted form.
This document addresses wastewater systems in their entirety and is applicable to systems at any level of development (e.g. pit latrines, on-site systems,
networks, treatment facilities).
The following are within the scope of this document:
— the definition of a language common to different stakeholders;
— objectives for the wastewater utility;
— guidelines for the management of wastewater utilities;
— service assessment criteria and related examples of performance indicators, all without setting any target values or thresholds.
The following are outside the scope of this document:

This part of IEC 61810 applies to electromechanical elementary relays (non-specified time all-or-nothing relays) for incorporation into low voltage equipment (circuits up to 1000 V alternate current or 1500 V direct current). It defines the basic functional and safety requirements and safety-related aspects for applications in all areas of electrical engineering or electronics, such as:

• general industrial equipment,

• electrical facilities,

• electrical machines,

• electrical appliances for household and similar use,

• information technology and business equipment,

• building automation equipment,

• automation equipment,

• electrical installation equipment,

• medical equipment,

• control equipment,

• telecommunications,

• vehicles,

• transportation (e.g. railways).

Compliance with the requirements of this standard is verified by the type tests indicated.

In case the application of a relay determines additional requirements exceeding those specified in this standard, the relay should be assessed in line with this application in accordance with the relevant IEC standard(s) (e.g. IEC 60730-1, IEC 60335-1, IEC 60950-1).
