This document deals with the assessment of the proportion of reused components in products on a horizontal level, which can be applied at any point in the life of the product.

It applies primarily to electrical and electronic products, but could be also applied to other product types.

This document is intended to be used in the assessment of the proportion of reused components in products. It can be also used by technical committees when developing assessment methods dedicated to their product or product-group publications.

Aspects like performance, validation, verification and suitability of reused components are not in the scope of this document. It is the responsibility of the user of this document to address these aspects.

This part of IEC 62822 applies to equipment for resistance welding and allied processes designed for occupational use by professionals and for use by laymen.

More generally, this document covers equipment for which the welding current flows in an electrical circuit whose geometry cannot be changed and regardless of the technology of the current generator (for example LF-AC, MF-DC for spot or seam welding or capacitive discharge used for stud welding).

NOTE 1 Allied processes as resistance hard and soft soldering or resistance heating achieved by means comparable to resistance welding equipment are included as well.

This document specifies procedures for the assessment of human exposure to magnetic fields produced by resistance welding equipment. It covers non-thermal biological effects in the frequency range from 0 Hz to 10 MHz and defines standardized test scenarios.

NOTE 2 The general term “field” is used throughout this document for “magnetic field”.

NOTE 3 For the assessment of exposure to electric fields and thermal effects, the methods specified in the Generic Standard IEC 62311 or relevant basic standards apply.

This document aims to propose methods for providing EMF exposure data that can be used to assist in the assessment of the workplace, especially when the conditions of use of the equipment are not known. When these are technically constrained (for example, a double hand control imposes the position and posture of the user), the data can be directly exploitable if they fall within the scope specified by the manufacturer or the integrator.

Other standards can apply to products covered by this document. In particular this document cannot be used to demonstrate electromagnetic compatibility with other equipment. It does not specify any product safety requirements other than those specifically related to human exposure to electromagnetic fields.

This document proposed several methods to assess the exposure to EMF from simple to sophisticate. In return, the last is also the most precise.

This part of IEC 62321 specifies procedures for the screening of di-isobutyl phthalate (DIBP), di-n-butyl phthalate (DBP), benzyl butyl phthalate (BBP), di-(2-ethylhexyl) phthalate (DEHP) in polymers of electrotechnical products by using high performance liquid chromatography with ultraviolet detector (HPLC-UV), thin layer chromatography (TLC) and thermal desorption mass spectrometry (TD-MS).

High performance liquid chromatography with ultraviolet detector (HPLC-UV), thin layer chromatography (TLC) and thermal desorption mass spectrometry (TD-MS) techniques are described in the normative part of this document. Fourier transform infrared spectroscopy (FT-IR) is described in the informative Annex of this document.

The HPLC-UV and TLC technique is suitable for screening and semi-quantitative analysis of DIBP, DBP, BBP and DEHP in polymers that are used as parts of the electrotechnical products upper than 300 mg/kg.

The TD-MS techniques are suitable for screening and semi-quantitative analysis of DIBP, DBP, BBP and DEHP in polymers that are used as parts of the electrotechnical products upper than 300 mg/kg.

The FT-IR technique in Annex A is suitable for preliminary screening of total phthalates (DIBP, DBP, BBP, DEHP and so forth) in polymers that are used as parts of the electrotechnical products upper than 50 000 mg/kg.

These test methods have been evaluated by testing PE (polyethylene), PVC (polyvinyl chloride) materials containing individual phthalates between 500 mg/kg to 3 000 mg/kg as depicted in the normative and informative parts of this document. The use of the methods described in this document for other polymer types, phthalate compounds or concentration ranges other than those specified above has not been specifically evaluated.

Annex E shows a flow chart as an example of how each method included in this document can be used for screening. Test methods in this document differs from IEC62321-8 in that all phthalates in this scope are not separated to each phthalate. Detectable combinations are DIBP + DBP + BBP and DEHP for HPLC-UV technique, DIBP + DBP, BBP and DEHP for TLC technique and TD-MS technique, total phthalates for FT-IR technique. FT-IR is a suitable analytical technique for preliminary screening in the first step of phthalates screening. Be aware how to judge in the achieved results (positive – doubtful – negative results). These test methods are characterized by a shorter measuring time compared with IEC62321-8 because all phthalates in this scope are not separated to each phthalate.

NOTE See Annex F for commonly used phthalates in products.

This document provides guidance on:

the meaning and significance of dependability from a business, technical and financial perspective;

achieving dependability through suitable adaptation of organizational management systems such as those described in the ISO 9000 series (Quality management), ISO 26000 (Guidance on social responsibility) and the ISO 55000 series (Asset management);

the activities that need to be integrated into management systems and life cycle processes in order to achieve dependable systems, products and services;

planning and implementing dependability activities throughout the life cycle to achieve and assure required outcomes, taking into account factors such as costs, safety, the environment, customer goodwill, brand and reputation.

This document is applicable to any type of system, both new and existing, to mass produced industrial or consumer products, to components and to services. This document addresses all elements of systems, products and services including hardware, software, data, processes, procedures, facilities, materials, and personnel required for operations and support.

This part of IEC 60068 provides the necessary information to assist in preparing relevant specifications, such as standards for components or equipment, in order to select appropriate tests and test severities for specific products and, in some cases, specific types of application.

The object of damp heat tests is to determine the ability of products to withstand the stresses occurring in a high relative humidity environment, with or without condensation, and with special regard to variations of electrical and mechanical characteristics. Damp heat tests may also be utilized to check the resistance of a specimen to some forms of corrosion attack.

This document / This part of IEC 60626 contains the definitions related to and the general requirements to be fulfilled by combined flexible materials for electrical insulation. This standard does not include mica papers used as a primary component, which are covered by IEC 60371, but insulation materials based on mica paper may be used as component of a combined flexible material. Materials which conform to this specification meet established levels of performance. However, the selection of material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.
