Foreword
This standard is the integration of the following criteria after revising.
--- GB/T 6626.1-1986 "mercury releasing getter Performance Test Method Test Method of mercury releasing getter mercury release characteristics";
--- GB/T 9506.6-1988 "nitrogen-doped barium getter film distribution test methods";
--- GB/T 9506.2-1988 "barium evaporable getter barium test method too."
This standard compared with the original standard main changes are as follows.
--- Cancel the test method mercury releasing getter mercury release characteristics of the terminology in the normative references in the new GB/T 4314
"Getter term";
--- The GB/T 6626.1-1986 "Test Method for mercury releasing getter performance test method mercury releasing getter mercury release characteristics" and
GB/T 9506.2-1988 "barium evaporable getter barium test method was" in the test system, method of consolidation;
--- Cancel test equipment fat-free ball;
--- The size of the test chamber test according to the intended use classification by metal emission classification;
--- The release amount of mercury, barium obtained after weighing the amount of heating time by a change within 5min 15min;
--- Mercury releasing characteristic tested by 400 ℃ began to raise to the start 500 ℃;
--- Cancel mean, standard deviation calculation method;
--- The amount of barium was canceled conformance testing;
--- Cancel the test report format;
--- The GB/T 9506.2-1988 "barium evaporable getter barium test method was" in evapotranspiration curve drawing methods from steam
Time Control statements be revised;
--- According to GB/T 1.1-2000 requirements were revised format.
This standard replaces the following criteria.
--- GB/T 6626.1-1986 "mercury releasing getter Performance Test Method Test Method of mercury releasing getter mercury release characteristics";

Getter metal release characteristics of test methods
1 Scope
This standard specifies the characteristics of getter metal release test methods, such as the total amount of mercury releasing mercury releasing getter, the standard amount of mercury release, mercury release characteristic curve
Test Method for wire and thermal stability, barium evaporable getter method was tested a barium amount of nitrogen-doped barium getter film distribution test methods.
This standard applies to devices with a vacuum getter.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.
GB/T 4314 getter term
GB/T 25494-2010 getter composition analysis test methods
3 Terms
GB/T 4314 as determined by the terms and definitions apply to this standard.
Test Method 4 release of metal
4.1 Principle
Getter metal emission tests, such as the total amount of mercury releasing mercury releasing getter, the standard interpretation of the amount of mercury, barium evaporable getter yield of barium, etc., were collected
Determination of the amount of metal released by "poor weight method."
4.2 Test equipment and conditions
When evaporable getter tested, recommended the sample chamber and the high frequency induction coil size are shown in Table 1. The specimen shall be in cylindrical specimens
Rooms, and high-frequency induction coil center. Typically, the sample is placed on top of the sample chamber can be directed towards the evapotranspiration horizontal position, using coaxial
Evapotranspiration. For antenna type pallet color picture tube getter, for the ET direction towards the opposite glass wall, at least with the sample specimen support frame
Chamber axis angle of 30 °; the sample in order to prevent displacement occurs during evapotranspiration, evapotranspiration should be tangential. see picture 1.
