CB Scheme - International Standard IEC

The CB Scheme is a vast, international arrangement established by the International Electrotechnical Commission (IEC) for mutual acceptance of test reports among participating certification organizations in the field of electrical and electronic equipment, representing a network of product certification organizations in more than 50 countries around the world. It benefits product manufacturers and distributors engaged in international trade by providing:

  • A single point of product testing for efficient global market access
  • Global acceptance of test reports leading to national certification in CB Scheme member countries
  • Unilateral acceptance of test reports in many developing countries that are not yet participating in the CB Scheme

On March 25, 2020, a new International Standard IEC 60335-2-118:2020 has been published. It deals with the safety of appliances for making ice cream and artisan gelato.

Appliances taken into account are those intended for commercial use and similar appliances not intended for normal household use but may nevertheless be a source of danger to the public, such as appliances intended to be used by laymen in shops, stores, by artisans or on farms, which rated voltage is not more than 250 V for single-phase appliances and 480 V for other appliances.

Appliances covered by this standard are provided with a refrigerant condensing unit which is usually incorporated, but for some appliances may be remote.

This standard also applies to the following types of appliances:

  • Mixers to make ice cream and similar pastry products in which, for the preparation of the product, a heating process is made within the appliance before the cooling process
  • Appliances for storing whipping cream mix in a refrigerated tank and for whipping the cream for the delivery process

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 labor, the national water supply authorities and similar authorities

This standard does not apply to:

  • Appliances with a refrigerating system operating with flammable refrigerant
  • Ice cream appliances for household use (IEC 60335-2-24)
  • Appliances intended 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, vapor or gas)

This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments.

On May 29, 2020, the consolidated version of IEC 60436:2015+AMD1:2020 was published (Edition 4.1). It defines the principal performance characteristics of electric dishwashers for household and similar use and describes the standard methods of measuring these characteristics.

IEC 60436:2015+A1:2020 applies to electric dishwashers for household and similar use that are supplied with hot and/or cold water. The object is to state and define the principal performance characteristics of electric dishwashers for household and similar use and to describe the standard methods of measuring these characteristics. This standard is concerned neither with safety nor with minimum performance requirements.

This edition constitutes a technical revision and includes the following significant technical changes with respect to the previous edition:

  1. Addition of a specification of the reference dishwasher G1222, addition of the microwave oven 752C, inclusion of standby/low power modes and updated cutlery and tableware items
  2. Combined cleaning and drying: combining the cleaning and drying performance evaluations into one test, along with the energy and water consumption evaluation, prevents an opportunity for circumvention if tests were performed separately. A dishwasher can detect whether soil is present (cleaning evaluation) or not (drying evaluation) and adjust the cycle to favor performance; combining the tests addresses this.
  3. New dish load items: new dish load items were incorporated which reflect consumer use. New items are stainless pots, coffee mugs, melamine plastic items and glass bowls. The new load items provide different shapes which challenge a dishwasher water spray patterns and provide additional surfaces for soil removal assessment.
  4. Detergent: a new detergent "D" is specified which mirrors current tablet formulations available on the market. Detergent type D is phosphate-free, with percarbonate instead of perborate bleach and more active enzymes.
  5. Repeatability and reproducibility improvements
  6. Addition of annexes for the evaluation of soil-sensing programs, rinsing performance, dishwasher filtration and of an annex on the inlet water temperature influence on energy consumption

On June 4, 2020, the consolidated version of IEC 60335-2-35:2012+AMD1:2016+AMD2:2020 (Edition 5.2) was published. It deals with the safety of electric instantaneous water heaters for household and similar purposes and intended for heating water below boiling temperature, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. Instantaneous water heaters incorporating bare heating elements are within the scope of this standard. Appliances not intended for normal household use but that nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account persons (including children) whose physical, sensory or mental capabilities, or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction, or children playing with the appliance. This fifth edition cancels and replaces the fourth edition published in 2002, including its Amendment 1 (2006) and its Amendment 2 (2009). The principal changes in this edition are as follows:

  • Converted notes to normative text (7.12, 7.102, 8.1.5, 22.104, and 22.109.3)
  • Deleted notes in 19.13, 22.109, and A.101
  • Added Annex R and 22.108 for appliances with programmable electronic circuits and added requirements for water heaters (22.50, 22.51)

This publication is to be read in conjunction with IEC 60335-1:2010.

On April 29, 2020, the standard IEC 60034-5:2020 was published, and on May 26, 2020, the standard IEC 60034-3:2020 was published. IEC 60034-5:2020 applies to the classification of degrees of protection provided by enclosures for rotating electrical machines. It defines the requirements for protective enclosures that are in all other respects suitable for their intended use and which, from the point of view of materials and workmanship, ensure that the properties dealt with in this document are maintained under normal conditions of use. IEC 60034-3:2020 applies to large, three-phase synchronous generators having rated outputs of 10 MVA and above, driven by steam turbines or combustion gas turbines. This seventh edition cancels and replaces the sixth edition published in 2007.

This edition includes the following significant technical changes:

  • Title modified
  • Scope extended to synchronous compensators
  • Rotor overcurrent requirements added
  • Impact of stator harmonics on rotor unbalanced load capability introduced
  • Synchronization requirements added
  • Adjustments of temperatures or temperature rise revised for gas turbine applications
  • Requirements for auxiliaries updated
