【英文标准名称】: Standard Specification for Tungsten-Rhenium Alloy Thermocouple Wire 【原文标准名称】: 钨-铼合金热电偶丝的标准规范 【标准号】: ASTM E696-2007 【标准状态】: 现行 【国别】: 【发布日期】: 2007 【实施或试行日期】: 【发布单位】: 美国材料与试验协会(US-ASTM)【起草单位】: E20.04【标准类型】: (Specification)【标准水平】: ()【中文主题词】: 合金;铼;温度测量;热电偶;钨;热电偶丝【英文主题词】: rhenium alloy; thermocouples; thermodilatometry; tungsten【摘要】: 1.1 This specification covers the requirements for bare, solid conductor, tungsten and rhenium alloy thermoelements having diameters of 0.127 mm (0.005 in.) to 0.508 mm (0.020 in.) supplied in matched pairs. These thermoelements shall be suitable for use either in bead-insulated, bare-wire thermocouples, or in compacted metal-sheathed, ceramic insulated thermocouple material or assemblies.1.2 This specification covers the thermocouple combinations of tungsten-3 % rhenium versus tungsten-25 % rhenium (W3Re/W25Re) and tungsten-5 % rhenium versus tungsten-26 % rhenium (W5Re/W26Re; Type C). All information applies to both combinations unless otherwise noted.1.3 It is recognized that the alloys described are refractory and are not suitable for use at high temperatures in oxidizing atmospheres. All tests and processes described herein must be performed under conditions that are non-reactive to tungsten-rhenium alloys. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.【中国标准分类号】: N11【国际标准分类号】: 17_200_20【页数】: 3P.;A4【正文语种】: 作者: 0502 时间: 2014-5-20 16:15:49
