ASTM F1227 Standard Test Method for Total Mass Loss of Materials and Condensation of Outgassed Volatiles on Microelectronics-Related Substrates
ASTM F1227材料总质量损失和脱气挥发物冷凝的标准试验方法

ASTM F1227适用范围

1.1 This test method covers various thermoplastics and thermosets routinely used in the microelectronics industry. This test method covers a screening technique to determine volatile content of these materials when exposed to a vacuum environment. Two parameters are measured: total mass loss (TML) and collected volatile condensable materials (CVCM).

1.2 This test method describes the test apparatus and related operating procedures for evaluating the mass loss of materials being subjected to 25, 70, or 125°C at less than 5 Pa (0.05 mbars) for 24 h. The lowest temperature simulates storage conditions, while the middle and upper temperatures simulate soft bake and hard bake conditions encountered during micro-electronics manufacturing. The overall mass loss can be classified into noncondensables and condensables. The latter are characterized herein as being capable of condensing on a silicon wafer, glass plate, aluminum disk or other substrate, maintained at a temperature of 18°C.

NOTE 1--Unless otherwise noted, the tolerances are 18°C ± 3°C, 25°C ± 1°C, 70°C ± 1°C, and 125°C ± 1°C.

1.3 Any thermoplastic or thermoset can be tested. The materials may be tested in the "as-received" condition or prepared for test after various curing or manufacturing steps.

1.4 This test method is primarily a screening technique for materials and is not necessarily valid for computing actual contamination on a system or component because of possible differences in configuration, temperatures, and material processing. The three temperatures allow testing with respect to maximum expected service temperature. Also, many polymers cannot be tested at 125°C as they melt or undergo glass transition above 70°C.

1.5 The use of materials that are deemed acceptable in accordance with this test method does not ensure that the system or component will remain uncontaminated. Therefore, subsequent functional, developmental, and qualification tests should be used, as necessary, to ensure that material performance is satisfactory.

1.6 No data is yet available to evaluate minimum sample sizes. Sample sizes as small as 130 mg have been used.

1.7 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.8 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.

美标ASTM E595除气测试/Outgassing
ASTM E 595 outgassing test除气测试最新版本为ASTM E 595-15，已取代ASTM E 595-07版本。ASTM E595除气测试，使用筛选技术来确定的材料在真空状态下的挥发物含量。主要测试两个参数：总质量亏损（TML）和挥发物质冷凝量（CVCM）。另一个参数水汽量(WVR), 也可以在完成对TML和CVCM的测试后获得。

ASTM E595除气测试-测试项目和要求：
TML （total mass loss）总质量亏损,要求≤1%
CVCM （collected volatile condensable materials）挥发物质冷凝量, 要求≤0.1%
WVR （the amount of water vapor regained）水汽量
