Foreword
In order to implement the Environmental Protection Law of the People's Republic of
China; effectively use and save resources; reduce the impact of sanitary ceramics on
the environment and human health in the production, use and disposal process; and
guide and promote the production and use of environmentally friendly products; this
Standard is formulated.
This Standard stipulates the soluble lead and cadmium content limits of sanitary
ceramics in accordance with the environmental standards in "Civil Engineering and
Civil Building Materials" of South Korea. The radioactive specific activity index of
sanitary ceramics is formulated based on the use of raw materials for sanitary ceramics
in China. The principle of saving-water stipulates the maximum water consumption of
the toilet; meanwhile, it stipulates the recycling rate of industrial waste generated
during the production of sanitary ceramics.
This Standard has partially modified the technical contents of Certifiable Technical
Requirement for Environmental Labeling Products – Sanitary Ceramics (HBC 16-
2003).
Compared with the Certifiable Technical Requirement for Environmental Labeling
Products – Sanitary Ceramics (HBC 16-2003), the main changes of this Standard are
as follows:
--- Add the requirements for soluble lead and cadmium in sanitary ceramics, the
requirements for the maximum water consumption of urinals and squatting pans,
and the requirements for the recycling rate of industrial waste generated during
the production of sanitary ceramics;
--- Modify the radioactive specific activity index of sanitary ceramics;
--- Delete the requirements for water absorption and crack resistance of sanitary
ceramics.
This Standard is a recommended standard, applicable to the certification of
environmental labeling products in China.
This Standard was proposed by the Department of Science & Technology, and
Standards of the State Bureau of Environmental Protection.
Chief drafting organizations of this Standard: Environmental Development Center of
State Bureau of Environmental Protection; and National Research Center for Testing
Techniques for Building Materials.
This Standard was approved by the State Bureau of Environmental Protection on
August 23, 2006.
Technical Requirement for Environmental Labeling
Products – Sanitary Wares
1 Scope
This Standard specifies the definition, basic requirements, technical content and
inspection methods for the sanitary ceramics of environmental labeling products.
This Standard is applicable to sanitary ceramic products such as washbasins, toilets,
urinals, bidets, washing tanks, squatting pans, bathtubs, etc.
2 Normative References
The provisions in following documents become the provisions of this Standard through
reference in this Standard. For dated references, the subsequent amendments
(excluding corrigendum) or revisions do not apply to this Standard, however, parties
who reach an agreement based on this Standard are encouraged to study if the latest
versions of these documents are applicable. For undated references, the latest edition
of the referenced document applies.
GB 6566 Limits of Radionuclides in Building Materials
GB 6952 Sanitary Wares
GB/T 15555.2-1995 Solid Waste - Determination of Copper, Zinc, Lead, Cadmium
- Atomic Absorption Spectrometry
3 Terms and Definitions
3.1 Internal exposure index
The radioactive specific activity of the natural radionuclide radium-226 in sanitary
ceramics is divided by the limit specified in this Standard.
Expression formula:
Where:
IRa – internal exposure index;
Appendix A
(Normative)
Determination of Lead and Cadmium in Ceramic Samples
A.1 Principle
The powder samples of ceramics were treated by strong acid; and the heavy metals
of lead and cadmium in the solution were determined by flame atomic absorption
spectrometry.
A.2 Reagents
--- Nitric acid (HNO3, ρ = 1.42 g/ml), guaranteed reagent;
--- Preparation of nitric acid solution (1 + 1);
--- Deionized water or distilled water.
A.3 Apparatus
--- Atomic absorption spectrophotometer;
--- Filtering device: glass sand core filter, fiber filter membrane (pore size φ45μm);
--- Adjustable electric heating plate.
A.4 Sample preparation
The sample is cleaned, dried, smashed, shrunk, ground to pass through an 80μm (180
mesh) sieve, and stored in a clean weighing bottle for later use. The preparation
process shall avoid introducing impurities.
A.5 Preparation of test solution
Take 10 g of the sample (accurate to 0.0001 g) into a 100 ml beaker; add 25 ml of nitric
acid solution; rinse the wall of the beaker with a small amount of distilled water; stir
evenly; and cover with a watch glass. Place it on a 200°C low-temperature heating
plate to heat for 2h; cool to stand for 1h; immediately filter into a 50 ml volumetric flask,
rinse to the mark/ and shake well. This is the test solution of the sample to be tested.
A.6 Blank test solution
Use deionized water or distilled water to replace the sample; use the same procedures
and reagents as the sample; and prepare a blank test solution while processing the
