HJ/T 297-2006: PDF in English (HJT 297-2006)
Sector Standard for Environmental
Protection of the People's Republic of China
Technical requirement for environmental labeling products
Ceramics tiles
Issued on August 23, 2006 Putting into effect as of September 1, 2006
Issued by Ministry of Environmental Protection
HJ/T 297－2006
Forward
This standard is developed for the purpose of implementing the Law of the People's Republic of China
on Environmental Protection, minimizing the adverse impacts of the production, use and disposal of
ceramic tiles on the environment and human health, guiding and promoting the production and
utilization of environment-friendly products.
Referring to the environmental standard for the Building Materials for Civil Engineering and
Domestic Use of the Republic of Korea, this standard specifies the limits of soluble lead and cadmium
in ceramic tiles; identifies the friction coefficient of ceramic ground tiles according to the international
friction coefficient definition & classification, develops the radioactive specific activity limit for
ceramic tiles in line with the utilization situation of the raw materials of such tiles in China; and
identifies the recycling and reuse rate of industrial solid waste generated during the production of
ceramic tiles.
This standard is a recommendation standard and applicable to the certification of environmental
labeling products in China.
This standard is put forward by the Department of Science, Technology and Standards of the Ministry
of Environmental Protection.
Major organizations in charge of the development of this standard. Environment and Development
Center of MEP and National Building Materials Test Center.
This standard was approved by the Ministry of Environmental Protection on August 23, 2006.
This standard shall be put into effect as of September 1, 2006.
This standard shall be interpreted by the Ministry of Environmental Protection.
HJ/T 297－2006
Technical Requirement for Environmental Labeling Products
Ceramics Tiles
1. Application Scope
This standard specifies the definition, basic requirements, technical contents and determination
method for environmental labeling product ── ceramics tiles.
This standard is applicable to ceramics tiles manufactured from various technologies.
2. Standard Quotation Documents
The provisions of the following documents become the provisions of the current standard through
quotation. All quoted document with specified date and their follow-up medications (excluding
corrigenda) or revised versions shall be not applicable to the current standard. However, it is
encouraged that all stakeholders reaching an agreement according to this standard study the possibility
of utilizing the latest versions of these documents. The latest versions of all quotation documents
without any specific date are applicable to the current standard.
GB/T 4100 Ceramics tiles
GB 6566 Limit of radioactive nuclide for building materials
GB/T 15555.2－1995 Solid waste ── Determination of copper, zinc, lead and cadmium ──
Atomic absorption spectrometry
3. Terminology and Definition
3.1 Internal radiation index
It refers to the quotient of the radioactive specific activity of natural radioactive nuclide of radium-226
in ceramics tiles divided by the limit specified by the current standard.
Its formula is as the following.
IRa = CRa /200
Where IRa──Internal radiation index；
CRa ── The radioactive specific activity of natural radioactive nuclide radium -226 in ceramics
tiles, Bq/kg；
200 —— It refers to the limit for radioactive specific activity of radioactive nuclide of
radium-226 in ceramics tiles specified in this standard with the consideration of only internal
radiation with unit as Bq/kg.
3.2 External radiation index
It refers to the summary of the quotient of radioactive specific activity of natural radioactive
nuclide radium -226, thorium-232 and potassium -40 in ceramics tiles divided by the limit of
individual existence specified by the current standard.
The formula is as the following.
Where Iγ —— external radiation index;
CRa, CTh, CK ── is the radioactive specific activity of natural radioactive nuclide of radium-226,
thorium-232 and potassium-40 respectively in ceramics tiles, Bq/kg；
370, 260 and 4200 ── They refer to the specified limits for radioactive specific activity of
natural radioactive nuclide radium -226, thorium-232 and potassium -40 with
individual existence in ceramics tiles specified in the current standards under only
external radiation, Bq/kg.
3.3 Radioactive specific activity
It is the quotient of radioactive specific activity of certain radioactive nuclide in substance
divided by its mass.
The formula is as the following.
C = A/m
Where C── radioactive specific activity, Bq/kg；
A── radioactive specific activity of radioactive nuclide, Bq；
m── substance mass, kg.
4. Basic Requirements
4.1 The quality of the products shall comply with the requirements of national standard GB/T 4100.
4.2 The discharge of pollutants from the enterprises shall comply with the requirements of national or
local standards for the discharge of pollutants.
5. Technical Contents
5.1 The internal radiation index of ceramic tiles shall be no bigger than 0.9 and external radiation
index no bigger than 1.2.
5.2 The contents of soluble lead in ceramics tiles shall not exceed 20 mg/kg and soluble cadmium not
exceed 5 mg/kg.
5.3 The friction coefficient of ceramic floor tiles shall be no less than 0.5.
5.4 The recycling & reuse rate of industrial solid waste generated during the production of ceramics
tiles shall be over 70%.
6. Determination Method
6.1 Technical contents in 5.1 shall be tested according to the method specified in GB 6566.
6.2 Technical contents in 5.2 shall be tested according to the method specified in Annex A.
6.3 Technical contents in 5.3 shall be tested according to the testing process (dry method) specified in
M.4.4 of Annex M of national standard GB/T 4100 (Standard annex).
6.4 Technical contents in 5.4 shall be verified by site inspection and document review.
