Rock Salt and Glauber's Salt Chemical Analysis Part 4: Determination of Iron Phthalene Spectrophotometric Method

ASTM D7980-15(2023) 半导体工业中超纯水（UPW）抓斗样品中阴离子的离子色谱分析标准指南

1.1 This guide applies to ultrapure water that is thought to contain low ppt (parts-per-trillion, weight/weight) levels of anionic contaminants (for example, bromide, chloride, fluoride, nitrate, nitrite, phosphate, and sulfate). To minimize carry-over problems between analyses, it is best to limit the concentration of any one contaminant to approximately 200 ppt (although this limit is only an approximation and may vary, depending on the user’s application). 1.2 This guide is intended to help analysts avoid contamination of ultrapure-water samples, since contamination control is the primary challenge when quantifying ppt-level anions in grab samples. 1.3 This guide does not include recommendations for collecting samples from the water source. 1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM E300-03(2022) 工业化学品取样的标准实施规程

1.1 This practice covers procedures for sampling several classes of industrial chemicals. It also includes recommendations for determining the number and location of such samples, to ensure their being representative of the lot in accordance with accepted probability sampling principles. 1.2 Although this practice describes specific procedures for sampling various liquids, solids, and slurries, in bulk or in packages, these recommendations only outline the principles to be observed. They should not take precedence over specific sampling instructions contained in other ASTM product or method standards. 1.3 These procedures are covered as follows: Sections Statistical Considerations 7 – 11 Simple Liquids 12 – 27 Solids 28 – 35 Slurries 36 – 41 1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Sections 6, 19, 20, 30, 34 and 37. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D5196-06(2018) 生物应用级水标准指南

1.1 This guide is intended to describe the chemical and biological characteristics of water to be used whenever critical purity is essential to the use intended in laboratory bioapplications, for example, clinical, pharmaceutical, and biomedical. The importance of such a reagent is often underestimated despite the impact that it can have. 1.2 This guide is not intended to be used as a reference in preparing water for injectables. Generally, the appropriate use of this guide may include experiments involving tissue culture, chromatography, mass spectrometry, polymerase chain reaction (PCR), deoxyribonucleic acid (DNA) sequencing, DNA hybridization, electrophoresis, molecular biology or analyses where molecular concentrations of impurities may be important. 1.3 For all the other applications linked to an ASTM method and not bio-sensitive that require purified water, it is recommended that Specification D1193 or Guide D5127 be consulted. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM D3505-18 纯液体化学品密度或相对密度的标准试验方法

1.1 This test method describes a simplified procedure for the measurement of density or relative density of pure liquid chemicals for which accurate temperature expansion functions are known. It is restricted to liquids having vapor pressures not exceeding 79 993 Pascal (0.800 bar, 600 mm Hg (0.789 atm) at the equilibration temperature, and having viscosities not exceeding 15 cSt at 20°C. 1.2 Means are provided for reporting results in the following units: Density g/cm3 at 20°C Density g/mL at 20°C Relative density 20°C/4°C Relative density 15.56°C/15.56°C NOTE 1—This test method is based on the old definition of 1 L = 1.000028 dm3 (1 mL = 1.000028 cm3 ). In 1964 the General Conference on Weights and Measures withdrew this definition of the litre and declared that the word “litre” was a special name for the cubic decimetre, thus making 1 mL = 1 cm3 exactly. NOTE 2—An alternative method for determining relative density of pure liquid chemicals is Test Method D4052. 1.3 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 8, Hazards. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM E499/E499M-11(2017) 检测器探头模式下使用质谱检漏仪的泄漏标准实践

1.1 This practice covers procedures for testing and locating the sources of gas leaking at the rate of 1 × 10−7 Pa m3 /s (1 × 10 −8 Std cm3 /s)3 or greater. The test may be conducted on any device or component across which a pressure differential of helium or other suitable tracer gas may be created, and on which the effluent side of the leak to be tested is accessible for probing with the mass spectrometer sampling probe. 1.2 Two test methods are described: 1.2.1 Test Method A—Direct probing, and 1.2.2 Test Method B—Accumulation. 1.3 Units—The values stated in either SI or std-cc/sec units are to be regarded separately as standard. The values stated in each system may not be exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.4 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. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
