ASTM C289-2003集料的碱性硅酸盐潜在活性的标准试验方法(化学方法)

When this test method is used to evaluate the potential reactivity of siliceous components in the aggregate with alkalies in hydraulic-cement concrete, it must be used in combination with other methods. Do not use the results of tests by this test method as the sole basis for acceptance or rejection for sources with regard to ASR. Reactions between a sodium hydroxide solution and siliceous components in the aggregate have been shown to correlate with the performance of some aggregates in concrete structures. The results from this test method can be obtained quickly, and, while not completely reliable in all cases, they can provide useful data. This test method can be employed as a quality control tool to periodically check samples from an existing source with an acceptable service history.1.1 This test method covers chemical determination of the potential reactivity of an aggregate with alkalies in portland-cement concrete as indicated by the amount of reaction during 24 h at 80176C between 1 N sodium hydroxide solution and aggregate that has been crushed and sieved to pass a 300-956;m sieve and be retained on a 150-956;m sieve. 1.2 The values stated in SI units are to be regarded as standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. A specific precautionary statement is given in 5.7.1.

DIN EN 16602-70-21-2015航天产品保证.航天材料筛选用易燃性试验;英文版本 EN 16602-70-21-2014

This Standard defines a multi-test procedure for the determination of the flammability characteristics of non-metallic materials under a set of closely controlled conditions. The test procedure covers both individual materials and materials used in configuration. This Standard describes a series of tests to provide data for aid in the evaluation of the suitability of materials for use in a space vehicle crew compartment. The data obtained are in respect to the ease of ignition and the flame propagation characteristics of materials. All non-metallic materials are inherently flammable, the degree to which this is true is dependant on the chemical nature of the material itself and the environment to which the material is exposed. In the closed environment of a manned spacecraft this can lead to a potentially dangerous situation and close control is therefore required. This standard may be tailored for the specific characteristics and constrains of a space project in conformance with ECSS-S-ST-00.

DIN EN ISO 16264-2004水质.用流动分析(FIA和CFA)法和光度检测法测定可溶性硅酸盐

This International Standard specifies two methods, i.e. flow injection analysis (FIA) and continuous flow analysis (CFA), for the determination of soluble silicate ions in various types of water (such as ground, drinking, surface, leachate and waste water). Both methods are applicable to the determination of a mass concentration of silicate (SiO(Index2)) ranging from 0,2 mg/l to 20 mg/l (with working ranges 0,2 mg/l to 2,0 mg/l and 2 mg/l to 20 mg/l). Other mass concentration ranges are applicable, provided they cover exactly one decade of concentration units (e. g. 0,02 mg/l to 0,2 mg/l in SiO(Index2)). These methods can be made applicable to seawater by changing the sensitivity and by adapting the reagent and calibration solutions to the salinity of the samples.#,,#
