Replace the scope of IEC 62885-2 by following:

This part of IEC 62885 is applicable for measurements of the performance of mains-operated dry vacuum cleaners, including water filter vacuum cleaners, for commercial use.

The purpose of this document is to specify essential performance characteristics of dry vacuum cleaners for commercial use which are of interest to operators and to describe methods for measuring these characteristics.

NOTE 1 Due to the influence of environmental conditions, variations in time, origin of test materials and proficiency of the operator, some of the described test methods will give more reliable results when applied for comparative testing of a number of appliances at the same time, in the same laboratory and by the same operator.

NOTE 2 The methods here can be applied with modifications for surface-cleaning product types or technologies not currently covered within the scope.

For safety requirements, reference is made to IEC 60335-1 and IEC 60335-2-69.

This part of IEC 62282 defines the evaluation methods of typical performances for electric energy storage systems using hydrogen. This is applicable to the systems which use electrochemical reaction devices for both power charge and discharge.

The conceptual configurations of the electric energy storage systems using hydrogen are shown in Figure 1 and Figure 2. Figure 1 shows the system independently equipped with an electrolyzer module and a fuel cell module. Figure 2 shows the system equipped with a reversible cell module. There are an electrolyzer, a hydrogen storage and a fuel cell, or a reversible cell and a hydrogen storage as indispensable components, and a battery, an oxygen storage, a heat management system, a water management system and an overall management system as optional components. The performance measurement is executed in the area surrounded by the outside thick solid line square (system boundary).

Note: In the context of this international standard, the term “reversible” does not refer to the thermodynamic meaning of an ideal process. It is common practice in the fuel cell community to call the operation mode of a cell that alternates between fuel cell mode and electrolysis mode “reversible”.

A typical targeting application of the electric energy storage systems using hydrogen is in the class of energy intensive electric energy storage. The systems are recognized as critically useful for the relatively long-term power storage operation, such as efficient storage and supply of the renewable power derived electric energy and grid stabilization.

This international standard is to be used for data exchanges in commercial transactions between the system suppliers and customers. Users of this international standard may selectively execute test items suitable for their purposes from those described in this international standard.

This standard specifies test methods and an interpolation procedure for determining losses and efficiencies of converter-fed motors within the scope of IEC 60034-1. The motor is then part of a variable frequency power drive system (PDS) as defined in IEC 61800-9-2.

Applying the approach of the comparable converter, the motor efficiency determined by use of this standard is applicable for comparison of different motor designs only.

The standard also specifies procedures to determine motor losses at any load point (torque, speed) within the base speed range (constant torque range, constant flux range) based on determination of losses at seven standardized load points. This procedure is applicable to any variable speed AC motor (induction and synchronous) rated according to IEC 60034-1 for operation on a variable frequency and variable voltage power supply.
