标准简介

适用范围：

1.1 This practice describes techniques for the determination of evaporated barium yield, getter gas content, and getter carbon monoxide sorption capacity for barium flash getters used in electron devices. Test conditions are chosen to approximate use conditions.1.2 Auxiliary procedures for cleaning, for determining vacuum system leak-up rates, for flashing getters, and for determining barium content in both getter fill and films are also given.1.3 The various tests described are destructive in nature. In general the tests are semiquantitative but they can be expected to yield comparative information on a single-laboratory basis to the precision indicated. No information relative to multilaboratory reproducibility is available.1.4 List of Methods DescribedMethod SectionBarium Content, Determination of, 9Acid-Base Titration Method 9.6Complexation (Titration) Method 9.7Gravimetric Method 9.4Photometric Method 9.5Weight Difference Method 9.8Barium Yield, Determination of, 10Carbon Monoxide Sorption Characteristics, Determination of 12Cleaning Procedures 6Getter Mount 6.3Getter Test Bulb 6.4Flashing Procedures 8Gas Content, Determination of for Doped Getters: 11Hydrogen 11.7Nitrogen for Undoped Getters: 11.8Preflash Gas Content 11.5Total Gas Content 11.4Leak-Up Rates, Determination of 71.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
