These appliances are not intended for household and similar purposes. They are used for commercial processing of food in areas not open to the public, for example in kitchens of restaurants, canteens, hospitals and in commercial enterprises such as bakeries and butcheries.
The electrical part of appliances making use of other forms of energy is also within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by these types of appliances.
Attention is drawn to the fact that - for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary; - in many countries additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities; - in many countries, additional requirements are specified for pressure appliances.
This standard does not apply to - appliances designed exclusively for industrial purposes; - appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere dust, vapour or gas ; - appliances for continuous mass production of food; - battery-operated appliances.
This seventh edition cancels and replaces the sixth edition published in This edition includes the following significant technical changes with respect to the previous edition: a the text has been aligned with IEC ; b some notes have been converted to normative text or modified Clause 1, 7. This Part 2 is to be used in conjunction with the latest edition of IEC and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used.
It was established on the basis of the sixth edition of that standard. Passive RF and microwave devices, intermodulation level measurement - Part 6: Measurement of passive intermodulation in antennas. IEC defines the test fixtures and procedures recommended for measuring levels of passive intermodulation generated by antennas, typically used in wireless communication systems.

This second edition cancels and replaces the first edition published in This edition includes the following significant technical changes with respect to the previous edition: a. Utility-interconnected photovoltaic inverters - Test procedure for over voltage ride-through measurements. This document is most applicable to large systems where PV inverters are connected to utility high voltage HV distribution systems.
However, the applicable procedures may also be used for low voltage LV installations in locations where evolving OVRT requirements include such installations, e.
This document is for testing of PV inverters, though it contains information that may also be useful for testing of a complete PV power plant consisting of multiple inverters connected at a single point to the utility grid.
