ASTM F1087-02(2023) 衬垫材料对水分线性尺寸稳定性的标准试验方法

1.1 This test method covers a procedure to determine the stability of a gasket material to linear dimensional change due to hygroscopic expansion and contraction. It subjects a sample to extremes, that is, oven drying and complete immersion in water, that have shown good correlation to low and high relative humidities.2 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 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. 1.4 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.

Standard Test Method for Linear Dimensional Stability of a Gasket Material to Moisture

ASTM F336-02(2023) 腐蚀性环境用非金属包覆垫片的设计和施工标准实施规程

1.1 This practice covers the designs, sizes, classifications, and construction of enveloped gaskets for severe corrosive applications. The envelope serves as the corrosion resistant member of the composite gasket and is a nonmetallic material such as polytetrafluoroethylene, PTFE, or related materials. The inserts are nonmetallic gasketing materials with or without metal reinforcement. Other types of composite gaskets are covered in Classification F868. 1.2 This standard is based directly upon ANSI B16.21–2011; for that reason units are as ANSI stated in inches. 1.3 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. 1.4 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.

Standard Practice for Design and Construction of Nonmetallic Enveloped Gaskets for Corrosive Service

ASTM F2378-05(2023) 薄板、复合材料和固体形式原位垫圈材料密封性的标准试验方法

1.1 This test method covers a means of evaluating the sealing properties of sheet, composite, and solid form-in-place gasket materials (see Classification F104 or F868) at room temperature, and may be used for fluid (gas or liquid) leak rate measurements. It utilizes relatively short hold times and is not intended to predict long-term performance in application. 1.2 This test method is suitable for evaluating the sealing characteristics of a gasket material under different press loads by measuring the leakage rate. This test method may be used as an acceptance test when the producer and user have agreed to specific test conditions for the following parameters: (1) test medium, (2) internal pressure of the medium, (3) press load on the gasket specimen, and (4) the surface finish of the platens. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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.

1.1 This test method provides a means of measuring the amount of creep relaxation of a laminated composite gasket material at a predetermined time after a compressive stress has been applied. 1.2 Creep relaxation is measured by means of a calibrated bolt with dial indicator. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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.

T/ICMTIA CM0035-2023 半导体硅材料制程装置用密封垫片

半导体材料提纯作为发展半导体器件的重要基础。由于大规模和超大规模集成电路的工艺要求,为得到N12级高纯度的硅材料，原料和中间体的高纯度和生产环境的高洁净度成为影响产品质量的一个突出问题。极微量的杂质混入对半导体的特性和芯片的良率均会造成极其严重的影响。因而在半导体材料和元件生产过程中对杂质必须进行严格控制。 垫片作为螺栓法兰密封组合装置中重要的组成部分，它的密封性能、可靠性和清洁度也同样影响着制程的稳定性和产品质量。密封垫片是半导体硅材料行业得到广泛应用且不可或缺的基础件，但国内外一直没有对用于制造半导体硅材料工艺装置和管道上的密封垫片作出明确的技术要求规范，如密封垫片的类型、质量要求、性能参数、清洁度要求等。 为了与现行行业相适应，也避免因垫片质量影响成品质量，特编制本文件。 本文件旨在确立半导体硅材料制程装置用密封垫片设计、制造、性能、选用所必须的要求。
