Specifies requirements for dry-type power transformers (including auto-transformers) having values of highest voltage for equipment up to and including 36 kV. The following small and special dry-type transformers are not covered by this standard:
-instrument transformers (covered by IEC 60185 and 60186);
-transformers for static convertors (covered by IEC 60084, 60119 and 60146).

Medical electrical equipment - Part 2: Particular requirements for the safety of short-wave therapy ...
This standard concerns the safety of short-wave therapy equipment having a rated outpout power not exceeding 500 W.
This second edition revises earlier shortcomings and deals in greater detail with inductive applicators.
Safety of household and similar electrical appliances - Part 2: Particular requirements for commerci...
Is to be used in conjunction with IEC 335-1, third edition. Deals with the safety of commercial appliances (cooking ranges, ovens, hobs and hob elements), whose rated voltage is no more than 250 V for single phase a.c. appliances and 480 V for other appliances. The electrical part of appliances making use of other forms of energy is also within the scope of this standard.
Standard Method of Fire Test of Light Diffusers and Lenses
1. Scope
1.1 This test method is applicable to materials employed in light diffusers and lenses.
1.2 It is the intent that tests made in conformity with this test method will develop data to enable regulatory bodies to determine the acceptibility of such material when employed in locations where performance in terms of "falling from an installed position before igniting" is…
Directly heated positive step-function temperature coefficient thermistors. Part 1: Generic specific...
Applies to directly heated positive temperature coefficient
thermistors, insulated or non-insulated, having a resistance
temperature characteristic which approximates to a step-function.
Typically they are made of ferro-electric semi-conductive materials.
Specifies the conditions for approval, acceptance and continuous
quality control. Defines the terminology for the thermistors covered
by this…
Safety of hand-held motor-operated electric tools. Part 2: Particular requirements for concrete vibr...
Applies to concrete vibrators, the active part (vibrator bottle) of which is intended to be immersed into the mass of concrete to be vibrated. Stationary concrete vibrators intended to vibrate concrete moulds, for example for prefabricated concrete elements, are not within the scope of this standard.
Measuring methods for properties of gyromagnetic materials intended for application at microwave fre...
Describes methods of measuring the specified properties of materials generally referred to as ferrites for application at microwave frequencies and is a guide for the drafting of specifications for general use in ferrite technology. This standard should be read in conjunction with IEC 60392.
