ISO 5796-2000橡胶配合剂天然碳酸钙试验方法

1 This International Standard specifies the methods to be used for the evaluation of natural calcium carbonate (chalk or limestone) ground to a dry powder for use in the rubber industry.\nNOTE 1 Classification of natural calcium carbonate according to fineness and chemical purity and typical physical and\nchemical properties for use in the rubber industry are given in informative annex D.\nNOTE 2 This International Standard does not cover calcium carbonates prepared by precipitation from solution.\n2 There are two sets of analytical methods listed in this International Standard. In the body of the text (4.8.2 to 4.8.4), the traditional spectrophotometric methods are given; these are obsolescent, time-consuming and use a chlorinated solvent. It is recommended that these methods be phased out and replaced by the atomic absorption methods listed in annexes A, B and C.

BS 6463-101-1996生石灰、熟石灰与天然碳酸钙.试验用试样的制备方法

Sampling powdered, granular and lump limes, milk of lime and lime putty.

BS 6463-102-2001生石灰、熟石灰与天然碳酸钙.化学分析方法

This part of BS 6463 describes methods for the chemical analysis of quicklime, hydrated lime and natural calcium carbonate. It describes both classical methods and methods which use atomic absorption spectrometry (AAS).\nIt gives classical chemical methods for:\n—fluorine, matter insoluble in acetic acid, matter insoluble in hydrochloric acid;\n—loss on ignition, neutralizing value;\n—free water in hydrated lime and also in lime putty;\n—total sulfur;\n—carbon dioxide in carbonate.\nIt gives flame atomic absorption spectrometric (AAS) methods for aluminium, cadmium, chromium, cobalt, copper, iron, lead, magnesium, manganese, nickel, silicon, silver and zinc.

BS 6463-103-1999生石灰、熟石灰与天然碳酸钙.物理试验方法

This part of BS 6463 describes methods for physical testing which have been found to be useful in the UK and which are outside the scope of BS EN 459-2.

BS PD 6682-9-2003集料.欧洲试验方法标准的使用导则

This part of PD 6682 gives guidance on the use of each of the European test method standards foraggregates, BS EN 932, BS EN 933, BS EN 1097, BS EN 1367, BS EN 1744 and BS EN 13179. Thesespecify tests for the following properties of aggregates:a) general;b) geometrical;c) mechanical and physical;d) thermal and weathering;e) chemical;f) filler aggregate used in bituminous mixtures.Additional test methods, specific to particular end uses, are not discussed in this part of PD 6682. Thesetests are specified in BS EN 13055-1:2002, Annex A and Annex B, for lightweight aggregates for concrete,mortar and grout; BS EN 13055-2:20002), Annex A and Annex B, for lightweight aggregates for unboundand bound applications; BS EN 13383-2 for armourstone and BS EN 13450:2002, Annex A, Annex C,Annex D, Annex E, Annex F and Annex G for railway ballast.
