Preferred number series for resistors and capacitors
SIST EN 60063:2015

IEC 60063:2015 provides series of preferred values for the resistance of resistors and for the capacitance of capacitors. The definition of such series with a defined numeric resolution is a basic prerequisite for the marking and coding of capacitors and resistors with their respective capacitance or resistance values as described in IEC 60062. This edition includes the following significant technical changes with respect to the previous edition: - revision of the information on a relationship between an E Series and the tolerance of a resistance or capacitance value of a respective component; - introduction of advice on a possible deduction from the marking of a component to an associated E Series and also to an associated tolerance; - complete editorial revision.

Preferred diameters of wire terminations of capacitors and resistors
SIST EN 60301:2012

IEC 60301:2012 gives a series of preferred diameters of the finished wire terminations of capacitors and resistors for use in electronic equipment. This third edition cancels and replaces the second edition, published in 1971, and its Amendment 1, published in 1972, and constitutes a technical revision. The main technical changes with respect to the second edition are the following: - employment of SI units only in the normative part of this standard, causing transfer of all imperial dimensions from Table 1 to the informative Annex A, - addition of two smaller diameters of wire terminations in Table 1, and - tightening of the tolerance ranges defined by minimum and maximum diameters in Table 1.

Method for the determination of the space required by capacitors and resistors with unidirectional terminations
SIST EN 60717:2012

IEC 60717:2012 applies to capacitors and resistors with unidirectional wire terminations intended for use in electronic equipment. This standard provides a method for determination of the space required by capacitors and resistors with unidirectional wire terminations. NOTE: Instead of measuring the actual space, it may be sufficient to ensure that a component fits into the maximum space for which it is designed. This may be achieved by means of fixed gauges. The main technical changes with respect to the first edition are the following: - employment of the millimetre-based grid, the preferred grid system given in IEC 60097, - employment of SI units only, causing deletion of the imperial dimensions from Table 1, - reduction of the tolerance on the chamfer depth in Figure 1, and - introduction of requirements on information to be given in a relevant specification.

IEC 60915:2006 contains preferred dimensions for shaft ends and bushes and for the mounting of single-hole, bush-mounted, shaft-operated variable capacitors, variable resistors and potentiometers. If other dimensions not listed in this standard have to be used, it is recommended to select them also from IEC 60390 and IEC 60620. This second edition cancels and replaces the first edition published in 1987 and constitutes a minor revision, related to tables, figures and references.

Household and similar electrical appliances - Safety - Part 2-39: Particular requirements for commercial electric multi-purpose cooking pans
kSIST FprEN 60335-2-39:2012

IEC 60335-2-39:2012 deals with the safety of electrically operated commercial multi-purpose cooking pans not intended for household and similar use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral and 480 V for other appliances. This standard also deals with pressurized appliances and appliances with pressurized parts. These appliances are used for processing food for commercial consumption, for example in kitchens of restaurants, canteens, hospitals and in commercial enterprises such as bakeries, butcheries, etc. 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 may be necessary. The principal changes in this edition as compared with the fifth edition of IEC 60335-2-39 are as follows (minor changes are not listed): - addition to definition of portable appliances, atmospheric multi-purpose cooking and rated pressure; - deletion of equipotential symbol 5021 of IEC 60417 covered by Part 1; - addition of instructions for multi-purpose cooking pans; - modification on leakage current permissible for portable class l appliances; - addition to abnormal test requirements; - addition to mechanical hazard test for multi-purpose cooking pans; - addition of construction test for multi-purpose cooking pans; - addition to construction requirements for lids and theirs grips; - addition to construction requirements for positioning of pressure reliefs; - addition to construction's fixed appliances which are moved forward and backward for cleaning purposes.
The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of publication. Keywords: Multi-purpose cooking pans.
