3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Hazardous substances harmfulsubstances
Furniture product contains can cause disease or make declining health substances.
3.2
Volatile hazardous substances volatileharmfulsubstances
Furniture products released into the air of harmful substances.
3.3
Contact hazardous substances contactharmfulsubstances
Direct contact with human furniture and the harmful substances.
4 types of hazardous substances
Furniture kind of harmful substances include.
a) harmful elements;
b) harmful compounds;
c) radionuclides;
d) other hazardous substances.
Identifying harmful substances
Furniture of harmful substances, mainly from furniture, raw and auxiliary materials and furniture production process, therefore, the identification of harmful substances furniture should
According furniture raw materials used in its production process categories to be judged. Furniture type and source of harmful substances in Table 1.
Table 1 furniture type and source of harmful substances
Source kinds of harmful substances and hazardous substances
Harmful elements paint, wood, plywood, plastic, textile, leather, metal plating, printing ink, etc.
harmful
Compound
Volatile organic compounds (formaldehyde, TVOC) paint, wood, plywood, plastic, textile, leather, printing ink, etc.
Preservatives (pentachlorophenol, 16 PAHs, etc.) wood, textiles, leather, adhesives, rubber, etc.
Aromatic amines (4-aminobiphenyl, benzidine other 24 kinds) textiles, leather, etc.
Fungicides (dimethyl fumarate, etc.) textiles, leather, etc.
Flame retardants (PBBs, PentaBDE octa Union
Benzene, ether, etc.)
Textiles, plastics, leather, etc.
Plasticizers (phthalates) paints, plastics, textiles, etc.
Radionuclides (radon, radium, potassium, thorium) of natural stone, artificial stone, ceramic components, etc.
Other harmful substances can be referred to the above-described method for identifying
6 samples of packaging, transportation and storage
6.1 Samples containing organic volatile harmful substances testing program, should be packaged.
6.2 sample transport and storage process should avoid chemical contamination and minimize storage time prior to the test sample.
6.3 samples before testing should be stored properly.
Select 7 detection method
7.1 detection method detection method if there are two or more of the same project, according to the equipment and technical conditions, choose to use.
7.2 If the same detection method according to the scope of a project set up several parallel method, should select the appropriate method based on detection range.
8 formulated reagents and solutions
8.1 Water detection method used, it does not indicate when additional requirements should be consistent with the three water GB/T 6682 regulations. It did not specify the solution
When formulated solvents, refers to water as the solvent.
Reagents 8.2 detection method used, it does not indicate when additional requirements were of analytical grade reagents.
Standard Solution 8.3 detection method used, should be GB/T 601 provisions of formulation and calibration.
8.4 preparations and products used in the detection method, preparation should be GB/T 603's.
8.5 Calibration Standards Standard should be used with the certificate, or the certificate with the use of standard reference material prepared according to standard methods.
9 Equipment
9.1 Equipment used in the detection method, there is traceability requirements according to relevant national regulations for checking and calibration.
9.2 Glass Container detection method used should be based on precision detection method requires a reasonable choice.
9.3 detection method when collecting gas samples in parallel, use the same model specifications of the sampling tube.
Pretreatment of the sample 10
10.1 volatile hazardous substances before the test project, should be pretreated samples, sample preparation methods should be standard products into
Row. Product standards are not prescribed, after unpacking the sample should be temperature (20 ± 5) ℃, relative humidity (50 ± 10)% of the environment, quenched and tempered at
Li least 72h.
10.2 pretreatment ambient air samples of volatile background concentrations of harmful substances shall not affect the measurement results of the sample principle.
11 test
11.1 should be strictly in accordance with the analysis step detection method prescribed inspection, the inspection process insecurity (poisoning, corrosion, burns
Etc.) should be protective measures.
11.2 of the same sample, volatile hazardous substances should be given priority item test.
11.3 sample contact hazardous substances in the product programs should use the human body can reach the site of sampling. In normal use of furniture products,
The reach or infrequent contact with the site, do not test.
The amount of the sample does not satisfy the amount of the sample 11.4 sample detection method requirements, do not test.
12 Data processing and analysis of results presentation
Operations and significant figures rounded 12.1 measured values should be consistent with GB T 8170, JJF1027 provisions /.
12.2 Expression of results. the results of the report of parallel determination of the arithmetic mean, calculated results are expressed to one decimal digit or digits shall be valid
Specified test methods of execution.
12.3 If the analysis results in a detection limit or less, you can use "not detected" expression analysis, but it should indicate the detection limit value.
