Chemical products for industrial use. Determination of the inflammation of solids ICS 13.300 A80 National Standards of People's Republic of China Chemical products for industrial use to determine the flammability of solid Posted 2008-05-12 2008-09-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis standard is equivalent to using NFT20-042. 1985 "Chemical products for industrial use flammable solid determination" (French version). Appendix A of this standard is an informative annex. This standard is managed by the National Standardization Technical Committee chemicals dangerous (SAC/TC251) and focal points. This standard is drafted by. Tianjin CIQ. Participated in the drafting of this standard. Jiangsu Exit Inspection and Quarantine, Chinese Academy of Inspection and Quarantine. The main drafters of this standard. Wangli Bing, Tang Lijun, in Yanjun, Xiongzhong Jiang, Zhou Lei, Zhou Xin. This standard is the first release. NFT Introduction This Standard on August 5, 1985 approved by the Director-General of the French Association for Standardization, on September 5, 1985 entered into force. Before publication of this standard, which no internationally relevant international standards, but it is with the 84/449/CEE directives of the Party Committee A10 Wears match. This standard is for those who engage in physical and chemical properties of chemicals (industrial use) analysis, in this case, you must write a Parts of the technical dossier, in order to provide a new set of content, or in accordance with the provisions of No. 82-950 preparation, taking into account the 79/831/CEE Terms On Sixth Amendment 67/548/CEE on the terms of the relevant provisions of hazardous substances. This standard includes determining a sample ignited at room temperature, atmospheric pressure, and the burning time was measured. International Technology Glossary. \u200b\u200bchemical products, industrial products, solid, powder products, pellets, pastes, hazardous ingredients, physical and chemical composition, Uncertainty, flammability, combustion speed calculation. Chemical products for industrial use to determine the flammability of solid Before the test methods in accordance with this standard test, the sample should be known to a potentially explosive performance information. Sample information prepared in accordance with this standard methods before the test does not mean that all suspected samples were considered flammable, but only for fast Speed \u200b\u200band combustion process dangerous combustion of the sample, which is often burning velocity exceeds a certain limit. When the sample temperature reaches a certain level of metal powder was also seen as combustibles.1 ScopeThis standard applies to determine the flammability of solid or liquid chemicals in powder form, granular or paste.2 Terms and definitionsThe following terms and definitions apply to this standard. 2.1 Under the experimental conditions in a solid sample combustion time is defined in seconds. Principle 3 The test sample to be tested is added to prepare a status of a particular mold, mold removal after firing under defined test conditions, whether the record Burning and burning time.4 Reagents and materials4.1 die Length 250mm, inner cross-sectional height 10mm, wide 20mm, as shown in Figure A. 1 FIG. Mold fixed on a metal support, metal Support slide freely in both stationary rod metal tray. 4.2 Firewood Its volume requirements can be covered with a metal mold (4.1).5 test procedure5.1 Requirements Prepare enough to fill a mold (4.1) of a representative sample of the powder or granular. If the test sample is sensitive to moisture, it needs to be tested as soon as possible. 5.2 Test A sufficient quantity of test sample (5.1) was added to the mold (4.1), the mold fell from the height 2cm hard surface metal tray, a total of three times. Lift the metal objects, spilled wipe excess sample in the mold fixing Firewood (4.2), together with the rotation and extrusion mold. Note. If the sample is a paste, then Firewood (4.2) on to a cross-sectional 1cm2, 250mm long strip to expand the test sample. Use the appropriate sources of ignition (a cluster of small flames or hot wire temperature is lower than 1000 ℃) is lit brick heaped top of the sample. When heaped like Combustion product length is 80mm, 100mm length record subsequent burning time. Test was repeated 6 times, each time using a cold Or at room temperature Firewood (4.2).6 Test Results6.1 Test Report Combustible solid samples to define the time, in seconds, to take steps based on the average of six tests carried out 5.2. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 21846-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 21846-2008_English as soon as possible, and keep you informed of the progress.
