Doplňujúce informácie
| Significance and Use |
|
3.1?Nonvolatile matter in solvents can adversely affect their cleaning properties. These test methods can be used to control soil contamination in the boiling solvent, which if allowed to become too high, can decrease the stability of the solvent. 3.2?These test methods can be used to establish manufacturing and purchasing specifications. |
| 1. Scope |
|
1.1?These test methods cover the determination of nonvolatile matter in halogenated organic solvents and admixtures. 1.2?Five test methods are covered, as follows: 1.2.1?Test Method AFor halogenated organic solvents or admixtures having less than 50 ppm nonvolatile matter; or where precision better than ?10 ppm is required. 1.2.2?Test Method BFor halogenated organic solvents or admixtures having more than 50 ppm nonvolatile matter or where precision of ?0.001 % (10 ppm) is satisfactory. 1.2.3?Test Method CFor low-boiling halogenated organic solvents or their admixtures (for example, methylene chloride, trichlorotrifluoroethane) that may superheat and cause bumping while evaporating to dryness with steam. A precision of greater than ?10 ppm can be attained. 1.2.4?Test Method DFor rapid measurement of nonvolatile matter in halogenated organic solvents and their admixtures and where precision better than ?10 ppm is required. 1.2.5?Test Method EFor halogenated organic solvents or admixtures and where precision better than ?10 ppm is required. 1.3?The values stated in SI units are to be regarded as 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, 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. |
