Determination of Certain Substances in Electrical and
Electronic Products – Part 1: Introduction and Overview
WARNING – Persons using this Part should be familiar with normal laboratory practice.
This Part does not purport to address all of the safety problems, if any, associated with its
use. It is the responsibility of the user to establish appropriate safety and health practices
and to ensure compliance with any national regulatory conditions.
1 Scope
This Part of GB/T 39560 refers to the sample as the object to be processed and measured. The
nature of the sample and the manner in which it is acquired is defined by the entity carrying out
the tests.
It is noted that the selection of the sample may affect the interpretation of the test results.
While this standard provides guidance on the disassembly procedure employed for obtaining a
sample, it does not determine or specify:
• the level of the disassembly procedure required for obtaining a sample;
• the definition of a “unit” or “homogenous material” as the sample;
• conformity assessment procedures.
NOTE: Further guidance on assessment procedures of the conformity may be found in GB/Z 30374-
2013[2].

4 Test Methods - Overview
4.1 Field of application
The contents of the test methods to determine the levels of certain substances are grouped into
important steps:
a) analytical test methods;
b) laboratory implementation.
Analytical test methods were developed and validated to ensure their suitability to the task. The
structure of each of the test methods are generally aligned in accordance with ISO 78-2:1999
where applicable, i.e.:
hexavalent chromium, etc.) in electrical and electronic equipment is widely used in reference
to analytical testing methods. Screening methods provide the analyst a convenient approach to
evaluate for the presence or quantity of certain substance(s) in samples. Screening may employ
qualitative or semi-quantitative methods. In some cases, a quantitative method may be used for
screening purposes if the actual targeted substance(s) are difficult to analyze directly (e.g.,
hexavalent Cr).
Depending on the screening results however, additional analysis methods may need to be
employed to definitively verify the presence or quantity of certain substances. These definitive
analysis methods are referred to as verification methods.
While X-ray fluorescence spectrometry (XRF) is the tool most commonly associated with the
screening approach, it is not limited to this analytical measurement technique. Users of this
family of standards will understand that multiple measurement techniques can be employed for
the purpose of “screening”.
Screening for hexavalent chromium [Cr(VI)] for example, can be accomplished by a total
chromium measurement using a non-destructive XRF analysis method. Similarly, total
chromium analysis could be performed by a destructive analysis using an inductively coupled
plasma measurement method. Either measurement can be effectively employed to evaluate for
the presence or quantity of hexavalent chromium since the concentration of the hexavalent
species can be no greater than the total chromium concentration value.
Likewise, a total bromine measurement using a non-destructive XRF analysis method or C-IC
method can be used in the same fashion. Either measurement can be effectively employed to
evaluate for the presence or quantity (PBBs) or (PBDEs) in a sample when relating the total
bromine content to the composition of these compounds.
In both examples however, the detection of elevated total element levels requires additional
verification method analysis (e.g., U...
