ASTM E1449-92(2011) 超临界液相色谱法术语和关系指南

1.1 This guide deals primarily with the terms and relationships used in supercritical fluid chromatography. 1.2 Since many of the basic terms and definitions also apply to gas chromatography and liquid chromatography, this guide is using, whenever possible, symbols identical to Practices E355 and E682. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

ASTM E1147-92(2005) 用液体色谱法估算分配系数(N-辛醇/水)的试验方法

1.1 This test method describes a procedure for the estimation of the log of the octanol/water partition coefficient (log Kow) of chemicals over the range from 0 to 8.1.2 This test method uses an empirically derived equation to relate the octanol/water partition coefficient to an experimentally determined retention time on a liquid chromatographic column.1.3 This test method has been designed to estimate log Kow values for both non-ionizable and ionizable compounds. This is accomplished by buffering the liquid chromatographic solvent at a pH that will force the test compound into either the non-ionized or ionized form.1.4 This test method requires some knowledge of the detector response to the chemical being tested.1.5 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 safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D4993-89(2003) 为反向渗透标定二氧化硅的计算和校正

In the design and operation of reverse osmosis installations, it is important to predict the SiO2 scaling properties of the concentrate stream. Because of the increase in the concentration of SiO2 and the change in pH, the scaling property of the concentrate stream will be quite different from that of the feed solution. This practice permits the calculation of the scaling potential for the concentrate stream from the feedwater analysis and the reverse osmosis operating parameters. Scaling by SiO2 will adversely affect the reverse osmosis performance. This practice gives various procedures for the prevention of scaling. The presence of certain metals, for example, Al+3, may significantly alter the solubility of SiO2 via formation of insoluble metal silicates. This practice does not address this phenomena. 1.1 This practice covers the calculation and adjustment of silica (SiO2) for the concentrate stream of a reverse osmosis system. The calculations are used to determine the need for scale control in the operation and design of reverse osmosis installations. This practice is applicable for all types of reverse osmosis devices (tubular, spiral wound, and hollow fiber).1.2 This practice is applicable to both brackish waters and seawaters.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.

ASTM D4948-89(2012) 测定从粘性液体中分离上层的标准试验方法

1.1 This test method covers the determination of the amount of liquid separated as an upper layer in a 24-h period from viscous solutions or dispersions that contain dispersed solids such as paints, enamels, pigmented lacquers, adhesives, polishes, and other similar materials. Note 1???The amount of clear liquid that separates during this test is one of the criteria in the United Nations Recommendations on the Transportation of Dangerous Goods2 for the placement of flammable viscous liquids into packing groups related to flash points (See 4.1). 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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.

Standard Test Method for Determination of the Upper Layer Separated from a Viscous Liquid

ASTM D4948-89(2006) 测定粘性液体上层分离的试验方法

The United Nations Committee of Experts on the Transport of Dangerous Goods in their recommended regulations place materials having a flash point below 23°C (73.5°F) in Packing Group II. However, if viscous substances such as paint and related coatings, adhesives, polishes, etc., meet certain requirements, they can be placed in Group III along with materials having a flash point between 23 and 60.5°C (73.5 and 140°F). One of the requirements is that less than 3 % of clear liquid separates from the bulk of the material when subjected to this test method. At the present time most international regulatory bodies such as the International Civil Aviation Organization (ICAO) and the International Maritime Organization (IMO) use the U.N. Recommendations. It is anticipated that most national transportation regulatory bodies will adopt the U.N. Recommendations as their regulations for control of transportation of hazardous materials. At present the United States permits the transshipment of hazardous materials through the United States to other countries under regulations of the IMO and ICAO.1.1 This test method covers the determination of the amount of liquid separated as an upper layer in a 24-h period from viscous solutions or dispersions that contain dispersed solids such as paints, enamels, pigmented lacquers, adhesives, polishes, and other similar materials. Note 18212;The amount of clear liquid that separates during this test is one of the criteria in the United Nations Recommendations on the Transportation of Dangerous Goods for the placement of flammable viscous liquids into packing groups related to flash points (See ).1.2 The values stated in SI units are to be regarded as the standard.
