E.4.2 Place the sample in a 3 L glass container, seal it and place it in an (80 ± 2) °C incubator for (120 ± 10) min; E.4.3 Remove the container with the sample from the incubator and cool to (60 ± 5) °C for odor determination. E.4.4 After being measured by 3 inspectors, return the container with the sample back to the (80 ± 2) °C incubator, and then other test personnel The measurement is carried out in accordance with E.4.3. E.4.5 At least 5 testers are required to participate in the determination and determine the level of odour according to Table E.1, if testing between testers The result gap is more than two grades and should be re-measured. E.4.6 The arithmetic mean of each scoring result is used to describe the odor characteristics. If the rating is between the two, the closest half is four. Round off. Table E.1 Odour level Grade odor characteristics Level 1 is not easy to feel Level 2 can be felt, but not pungent Level 3 can be noticeably felt, but not pungent Level 4 pungent Level 5 is very pungent Level 6 is intolerable

Appendix F

(normative appendix) Determination of volatile organic compounds (VOC) content F.1 principle In a constant temperature closed container, the volatile organic compounds in the sample are distributed between the gas and solid phases to achieve equilibrium, and the solid phase gas sample is taken. The gas chromatograph (GC/MSD) with mass selective detector was used for the determination, confirmed by selective ion detection, and quantified by external standard method. F.2 Instruments and reagents The reagents used were of analytical grade unless otherwise stated. F.2.1 Gas Chromatography-Mass Spectrometer F.2.2 Automatic Headspace Sampler F.2.3 Headspace sample bottle with Teflon-sealed silicone rubber mat F.2.4 10 μl airtight syringe F.2.5 Acetone F.2.6 toluene F.2.7 Correcting working solution Toluene is prepared at a concentration of 0.5 mg/ml, 1.0 mg/ml, 5.0 mg/ml, 10.0 mg/ml, respectively, using acetone or other suitable solvent. 50.0 mg/ml toluene/acetone solution (freshly prepared). F.3 Analysis steps F.3.1 Sample preparation The sample was tested after 7 days from the date of production. Take a representative sample, cut it to 5 mm × 5 mm or less and mix. Weigh 2.00 g of the sample from the mixture to the nearest 0.01 g. Place in the headspace sample bottle (F.2.3), cover with silicone rubber pad and aluminum cover, seal with sealing tool, put into the automatic headspace sampler to be tested set. F.3.2 Determination Gas chromatography-mass spectrometry conditions. Since the test results depend on the instrument used, it is not possible to give a universal parameter for chromatographic analysis. The following parameters have been proven It is suitable for testing. The headspace vial has a heating temperature of 120 ° C and a heating equilibration time of 45 min. a) Column. HP-5 MS 30 m × 0.25 mm × 0.5 μm or equivalent; b) Column temperature. 50 ° C (3 min) → 12/min.200 ° C ° C (4 min); c) inlet temperature..200 ° C; d) injection method. split ratio 1.20; e) carrier gas. helium, purity ≥ 99.999%, 1.0 ml/min; f) chromatography-mass spectrometry interface temperature. 250 ° C; g) Ionization mode. EI. F.3.3 Calculation of results F.3.3.1 Determination of correction factor 4 μl ± 0.04 μl calibration working solution (F.2.7), 10 μl micro-injector into 5 headspace sample bottles, quickly seal The mouth tool is sealed and placed in an automatic headspace sampler (F.2.2). After heating at 120 °C for 5 min, it is analyzed by gas chromatography-mass spectrometry. The correction factor (KG) was determined using the peak area and the corresponding concentration. F.3.3.2 Volatile organic compounds The correction factor corrected by the total peak area and acetone is calculated according to formula (1). AA K m Σ −= ×× (1) Where. EG - the content of volatile organic compounds in the sample, mg/kg; ∑A--the total chromatographic peak area in the sample; A0--blank chromatographic peak area; KG--correction factor; M--the mass of the sample, g; V--the injection volume of the standard solution, ml. Note. When taking 2 g sample, the volume is 20 ml of the headspace bottle, V is 4 μl; when taking 1 g sample, the volume is 10 ml of the headspace bottle, V is 2 μl, according to this analogy.
