ASTM E1066-95(2006) 氨比色泄漏检验的测试方法

This method is useful for locating and measuring the size of gas leaks either as a quality-control test or as a field-inspection procedure. It can be used to test critical parts or containers that will hold toxic or explosive gases or liquids or as a quick test for other containers. 1.1 This test method covers the testing of large single- and double-walled tanks, pressure and vacuum vessels, laminated, lined- or double-walled parts, complex piping systems, flexible containers (such as aircraft fuel tanks), glass-to-metal seals in hybrid packages, and systems that inherently contain or will contain ammonia (such as large tonnage refrigeration systems and fertilizer storage systems).1.2 This method can be used on piping, valves and containers with welded, fitted, or laminated sections that can be sealed at their ends or between their outer and inner walls and that are designed for internal pressures of 34.5 kPa (5 psig) or greater.1.3 Basic procedures are described based on the type of inspection used. These procedures should be limited to finding leakage indications of 4.5 x 10-12 mol/s (1 x 10-7 Std cm 3/s) or larger.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. (For more specific safety precautionary information see 7.4, 8.2, 9.4.1, and ) 103.1.

This International Standard specifies a titrimetric method for the determination of the total and alkali-soluble calcium and magnesium contents of crude sodium borates for industrial use. Modified procedures are described for special cases for the determination of total calcium content to eliminate interference by silica, iron or aluminium. The method is applicable to products in which the calcium con-tent, expressed as calcium, is not lower than 0,01 % (m/m) and not greater than 1,0 % (m/m), and in which the magnesium content, expressed as magnesium, is not lower than 0,01 % (m/m) and not greater than 0,2 % (m/m).

British Standard Methods of test for Orthoboric acid (boric acid), diboron trioxide (boric oxide), disodium tetraborates, sodium perborates and crude sodium borates for industrial use Part 0. General introduction This Part of BS 5688 has been prepared under the direction of the Chemicals Standards Committee. BS 5688 provides a comprehensive series of test methods for orthoboric acid, diboron trioxide, disodium tetraborates, sodium perborates and crude sodium borates for industrial use. This Part of BS 5688 is a revision of BS 5688 : Part 0 : 1979, which is withdrawn. In this revision the list of methods in table 1 has been brought up to date. The recommended names, in accordance with BS 2474 'Recommendations for names for chemicals used in industry', for the chemicals having the formulae H3BO3 and B2O3 are, respectively, 'orthoboric acid' and 'diboron trioxide'. The names 'boric acid' and 'boric oxide' are now non-preferred but may still appear in place of the recommended names in earlier parts of BS 5688 and in other British Standards. The titles of new Parts of this standard have been altered to incorporate the recommended terms.
