This Part replaces GB/T 7702.15-1997 "granular activated carbon coal quality test methods - Determination of ash." This section compared with the GB/T 7702.15-1997, main differences are as follows. a) according to the standard structure GB/T 1.1-2000 "Standardization Guide Part 1. Structure and rules are written standard" and GB/T 20001.4-2001 "work of standardization Part 4. Chemical analysis methods" have been adjusted; b) The rectangular gray ceramic dish to ash pan; c) Weigh the sample was adjusted to 1g ± 0.1g; d) require the sample is evenly distributed gray dish; e) burning time is reduced to 1h; f) The amount of the unit according to uniform regulations to be modified. This section proposed and managed by China North Industries Group Corporation. This section is drafted. Shanxi Xinhua Chemical Co., Ltd. The main drafters of this section. Hirohide late, Zhao Jijun, to Dong Yuan, Li Bing, Zhao Honghai, Zhang Xu, Li Ruomei. This part of the standard replaces the previous editions are. --- GB/T 7702.15-1987, GB/T 7702.15-1997. Test method for granular activated carbon coal quality Determination of ash1 ScopeThis section sets out the principles of granular activated carbon ash coal quality determination, procedures and results of calculation content determination. This section applies to granular activated carbon from coal - Determination of ash, is also applicable to the determination of other activated carbon ash.2 Normative referencesThe following documents contain provisions which, through GB/T reference in this 7702 constitute provisions of this part. For dated reference documents Member, all subsequent amendments (not including errata content) or revisions do not apply to this section, however, encouraged to reach under this section Parties to research agreement to use the latest versions of these documents. For undated reference documents, the latest versions apply to this section. Determination of GB/T 7702.1 Test method for granular activated carbon from coal quality water Principle 3 A certain quality of the sample after burning, the resulting residue representing the original sample mass fraction is ash.4 instruments and equipment4.1 balance, sense of volume 0.0001g. 4.2 electric oven, 0 ℃ ~ 300 ℃. 4.3 dryer, built-in color gel or anhydrous calcium chloride. 4.4 cupel, porcelain, rectangular, base length 45mm, bottom width 22mm, height 14mm. 4.5 muffle furnace. Preparation 5 samples 5.1 by quartering to take 5g ~ 10g sample, the sample was crushed and all through the 1.00mm sieve test. 5.2 The sample was placed in 150 ℃ ± 5 ℃ electric oven, and dried in a desiccator 2h, cooled to room temperature before use.6 measuring step6.1 cupel placed in a muffle furnace at 800 ℃ ± 25 ℃ burning about 1h, taken out into the dryer, cooled to room temperature and weigh (fine Indeed to 0.0001g), repeat until constant burning. 6.2 Weigh 1g ± 0.1g sample (accurate to 0.0001g), evenly distributed in the gray dish. 6.3 cupel placed about 300 ℃ muffle furnace, shut the door, open the vents (such as not leaving the door vents can be left 15mm Right gap), in less than 30min time the furnace temperature was slowly raised to 500 deg.] C, and maintained at this temperature for 30min, warmed to continue 800 ℃ ± 25 ℃, and at this temperature burning 1h. 6.4 cupel removed from the furnace and placed on a heat resistant porcelain or asbestos, cooling the air around 5min, cooled to room temperature in a desiccator (About 20min) after weighing. Burning 6.5 per 20min after weighing once, until the change in mass of not more than 0.0010g so far. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 7702.15-2008_English be delivered?Answer: Upon your order, we will start to translate GB/T 7702.15-2008_English as soon as possible, and keep you informed of the progress.
