1 Scope
This technical guiding document provides the general guidelines of determining the
environment-friendly use period of electronic information products that contain toxic
and hazardous substances or elements.
The content of this technical guiding document applies to the electronic information
products within the adjustment range of "Pollution Control and Management Methods
of Electronic Information Products", and in which the content of toxic and hazardous
substances or elements exceeds the limit requirements specified in SJ/T 11363-2006.
2 Normative references
The provisions in following documents become the provisions of this guiding
document through the reference in this guiding document. For dated references, the
subsequent amendments (excluding corrections) or revisions do not apply to this
Standard, however, parties who reach an agreement based on this guiding document
are encouraged to study if the latest versions of these documents are applicable. For
undated references, the latest edition of the referenced document applies.
SJ/T 11364 Marking for control of pollution caused by electronic information
products
3 Terms and definitions
The terms and definitions defied in SJ/T 11364 AND the following terms and
definitions apply to this technical guiding document.
3.1 technical environment-friendly use period
The environment-friendly use period determined by practice OR scientific methods
and testing techniques.
3.2 notional environment-friendly use period
The environment-friendly use period determined by the method of combining with
other use period concepts of the products.
3.3 techno-life
The expected average product lifespan determined according to the design.
4 General rules
4.1 Numerical range
The electronic information products of which the environment-friendly use period is
less than or equal to 10a [Noted by Translator. 10a = 10 years. See SJ/T 11364],
should select an integer between 1 and 10 as the product's environment-friendly use
period. The electronic information products of which the environment-friendly use
period is greater than 10a, should select an integer multiple of 5 as the product's
environment-friendly use period. When the environment-friendly use period of
electronic information products is not an integer multiple of 5, it should select a similar
and smaller integer multiple of 5 as the product's environment-friendly use period.
4.2 Method selection process
The manufacturer or importer of electronic information products should select an
appropriate method to determine the product's environment-friendly use period
according to the order shown in Figure 1.According to the method selection process
diagram, enterprises shall in-priority consider to use practice method and test method
to determine the technical environment-friendly use period of the products. If the
technical methods are not applicable, then it can choose one of the four kinds of
determination methods of notional environment-friendly use period, regardless of the
order, to determine the environment-friendly use period of the products.
5 Determination methods of environment-friendly use period
Figure 1 Method selection process diagram of environment-friendly
use period of electronic information products
5.1 Technical environment-friendly use period method
5.1.1 General rules
When the manufacturer or importer of electronic information products has enough
practice experience or scientific test technical means, it should select the technical
environment-friendly use period as the environment-friendly use period of the
Electronic information products ofwhich the environment-friendly useperiod is to be determinedIs
there a practice experience.
5.1.2 Practice method
Electronic information products under normal use conditions, if the toxic and
hazardous substances or elements in products occur the cases of leaking or mutation
for 5 set · times or more, the rounded shortest age limit of the occurrence of cases is
determined as the technical environment-friendly use period of the products.
5.1.3 Test method
When electronic information products occur no the cases of leaking or mutation of
toxic or hazardous substances or elements under normal use conditions, the technical
environment-friendly use period obtained according to the experimental techniques of
Chapter 7 is determined as the technical environment-friendly use period of the
products.
5.2 Notional environment-friendly use period method
5.2.1 General rules
When manufacturer or importer of electronic information products can not determine
the technical environment-friendly use period of electronic information products under
existing practices and technical conditions, it should use notional environment-friendly
use period as the environment-friendly use period of the products.
5.2.2 Safe-use period method
If the products have safe-use period, it should use the safe-use period as the
environment-friendly use period of the products.
5.2.4 Analogy method
The new electronic information products, of which the technical-environment use
period and safe-use period of the products have not been determined, should use the
environment-friendly use period of the products with same or similar production
technology and raw materials as their own environment-friendly use period.
5.2.5 Check-table method
For some electronic information products, their environment-friendly use period can
be determined according to Annex B.
7 Test techniques
It should use the internationally accepted test techniques to determine the technical
environment-friendly use period of the products.
Annex A
(Informative)
Participating drafting organizations of this instructive technical document
(It is listed in the sequence of the first letter of Chinese PINYIN. There is no
preference in the sequence)
Emerson Electric (China) Investment Co., Ltd.
Annex B
(Normative)
Average environment-friendly use period of some electronic information
products
This annex was jointly studied and made by the industrial representatives of Pollution
Control Standard on Electronic Information Products Working Group. It lists out the
average environment-friendly use period of some electronic information products at
current technical level. The purpose is to provide the industry community with the
basis for determining the environment-friendly use period of electronic information
products, and to avoid exaggerating identifications or inaccurate identifications that
may cause market confusion.
