DD IEC PAS 62596 pdf download – Electrotechnical products – Determination of restricted substances – Sampling procedure – Guidelines
1Scope
This PAS provides general sampling guidelines and strategies of sampling for electrotechnicalproducts, electronic assemblies,electronic components. in order to obtain samples that canbe used for analytical testing to determine the levels of restricted substances as described inthe test methods of lEC62321.Restrictions for substances will vary between geographicregions and from time to time.This PAS describes a generic process for the sampling of anysubstance which could be restricted.
This PAS does not provide:
· Full guidance on each and every product that could be classified as electrotechnical
equipment.Since there is a huge variety of electrotechnical components，with variousstructures and processes，along with the continuous innovations in the industry，it isunrealistic to attempt to provide procedures for the disjointment of every type ofcomponent.
Analysis procedures to measure the levels of restricted substances. This is covered byother standards (for example the future lEC 62321), which are referred to as the “teststandard” in this PAs.
– Guidelines for assessment of compliance.
. Guidance regarding other routes to gather additional information on restricted substances
in a product,although the information collected has relevance to the sampling strategies inthis PAS.
– Sampling procedures for packaging and packaging materials.
. Safe disassembly and mechanical disjointment instructions related to electrotechnical
products (e.g. Hg containing switches) and the recycling industry (e.g. how to handlecRTs or the safe removal of batteries)-

3Terms, definitions and abbreviations3.1 Terms and definitions
For the purpose of this document,the following terms and definitions apply.
NOTE As this PAS is closely related to IEC 62321，terms and definitions from that standard have not beenduplicated here.
3.1.1
electronic assembly
group of components，at least one of which is an electronic device, but in which individualparts may be replaced without damage to the assembly
[Definition H.2.5.9,IEC 60730-1:1999]
EXAMPLE Group of components mounted on a printed wiring board.
3.1.2
electronic components
electrical or electronic devices that are not subject to disassembly without destruction orimpairment of design use.They are sometimes called electronic parts,or piece parts
[Definition 3.1.5,IEC 62239:2008]
EXAMPLE Resistors，capacitors，diodes，integrated circuits，hybrids，application speclic integrated circuits,wound campanents and relays.
3.1.3
composite testing
testing two or more materials as a single sample that could be mechanically disjointed ifnecessary
3.1.3
electronics
electronic assembly and/or electronic component and/or field replaceable unit
3.1.4
field replaceable unitFRU
part，component or subassembly that is easily removed (mechanically disjointed)usingordinary tools
NOTE“Easily removed” consists of using ordinary tools to perform such functions as screwing or disconnecting,and only without inreversibly destroying the unit.
[Definition 3.7，IEC Guide 114:2005]
3.1.5
disassembly
process of taking apart an electrotechnical product; possibly using simple hand tools such asa screwdriver, pliers and wrenches
NOTE A disassembled unit can, in theory, be re-assembled and be made operational.3.1.6
disjointment
process of, in principle,separating the materials by mechanical actions such as: unscrewing.cutting, grinding, scratching and abrasive processes
NOTE A disjointed part or assembly cannot be re-assembled into an operational unit.3.1.7
homogeneous material
material that cannot be mechanically disjoined into different materials
NOTE 1 The term “homogeneous”means “of uniform composition throughour”. Examples of “homogeneousmaterials”are individual types of: plastics,ceramics,glass, metals,alloys,paper,board, resins and coatings.
NOTE 2 The term “mechanically disjointed”means that the materials can，in principle，be separated bymechanical actions such as: unscrewing, cutting,crushing,grinding and abrasive processes
