SAE AMS-2750E 高温测定法(中英文对照版)介绍

航空航天材料规范SAE AMS 2750D1. 范围：该规范描述了对热处理设备的温度要求。

包括温度传感器、仪器、热处理设备、系统精确度测试和温度均匀性测试。

这些对确保零件或原材料按照适用规范进行热处理，是必要的。

除非材质或过程规范特别规定，否则该规范不适用于加热或中间热处理，。

该规范适用于实验炉，参见第3.6节。

2. 适用文件：以下文件从订单发布之日起生效，并构成了该规范的一部分。

除非对使用的文件版本有专门的规定，否则供应商要使用最新版本的文件。

当参考文件取消，而且没有文件替代时，使用最新发行的那版文件。

ASTM文件可以从ASTM, 100 Barr Harbor Drive, 邮箱C700，West Conshohocken，PA19428-2959或获得。

ASTME 207，ASTM E 220，ASTM E 230，ASTM E 608，ASTM E 1129，ASTM MNL 7，ASTM MNL 12。

3. 技术要求温度传感器：温度传感器必须符合表1要求和如下要求。

一些例外情况在下文中有提到。

温度应该用此规范中规定的热电偶来测量，或用其他的精度相同或更高的热电偶或温度传感器来测。

热电偶用裸线或涂装线或MIMS线(矿物绝缘，金属铠装的)制成。

没有特殊说明的话，要求适用于所有温度传感器材料。

此规范中的“传感器”即指“温度传感器”。

从传感器首次校准或后来校准所得到的修正系数可以用来提高温度的精确度，且在此规范要求下要被使用。

校准：传感器应该有合格证明，注明校准数据的来源、理论测试温度，实际测试温度读数、校准方法和每个可追溯到NIST或其他认可的国家标准的校准温度的修正系数。

校准方法应符合ASTM E 220，ASTM E 207或其他国家标准的要求。

从毫伏到度或从度到毫伏的转化，应该遵守ASTM E 230或其他国家标准。

温度传感器必须在使用的温度范围内校准。

所有热电偶的校准点间隔不能超过250 o F(140 o C) ，不包括那些按照ASTM MNL 12或其他国家标准要求，在固定点上校准的热电偶。

A M S2750E高温测定法5年一次的更新，复查并重审了该规范以提高其使用量，技术革新导致了使用的变化。

变化范围较大并且没有做标记。

AMS2750E标准在真空炉中的应用张红梅【摘要】AMS2750E标准规定了各类真空炉型的温度校准精度和均匀性的要求,以及各类仪器、仪表的校准精度.目前各行业都在借鉴和使用该标准,而普通的真空炉不能满足AMS2750E标准要求.通过对其关键技术的解决和实施,研制了能够满足AMS2750E标准的真空炉,并且已经在航空、航天以及各行业领域内广泛使用.【期刊名称】《电子工业专用设备》【年(卷),期】2014(000)005【总页数】5页(P47-51)【关键词】AMS2750E标准;真空炉;温度校准;温度均匀性;传感器【作者】张红梅【作者单位】中国电子科技集团公司第二研究所,山西太原030024【正文语种】中文【中图分类】TB942AMS2750（航空材料性能）标准是SAE（汽车工程师学会）在1980年公布的。

在2005年推出了修订版AMS2750D，在2012年又推出了修订版AMS2750E。

AMS2750E标准规定了各类真空炉型的温度校准精度和均匀性的要求，以及各类仪器、仪表的校准精度。

而在Nadcap(国家航空和国防承包商认证程序的缩写)的构架下，主要的航空设备制造商的目的是提高技术，要求承包商（转包商）提高产品质量。

一些承包商（转包商）为获得Nadcap认证，对于真空炉的要求就是能够满足AMS2750E标准。

因此，在AMS2750E标准的严格要求下，对真空炉的设计要求就更加严格。

AMS2750E标准中规定了各类级别真空炉用传感器及其校准见表1。

表1 各类级别真空炉用传感器及其校准注：表中t表示温度AMS2750E标准中规定了各类级别真空炉炉温均匀性的要求见表2。

表2 各类级别真空炉炉温均匀性符合AMS2750E标准的真空炉，其关键技术在于真空炉的工艺温度控制、温度均匀性的保证、各类温度传感器以及各类控制仪表的选用与检测。

目前，随着各行各业的生产中都在使用或者借鉴AMS2750E标准，普通的真空炉已经不能满足各行业用户的使用要求。

基于AMS2750E标准的低温真空焊接设备温度均匀性的实现王成君;杨兆建【摘要】针对低温真空焊接设备在150～350℃范围内的温度均匀性差的问题,采用真空焊接设备热场分析理论,结合设备的温度场特征,通过在热电偶的测量端增加具有较高黑度的装置,实现了AMS2750E标准下,真空炉对于炉温均匀性±3℃的要求,并且在升温、保温阶段设备均温区内没有出现超温情况.【期刊名称】《电子工业专用设备》【年(卷),期】2015(044)010【总页数】5页(P42-45,65)【关键词】AMS2750E;温度均匀性;温度场;真空焊接【作者】王成君;杨兆建【作者单位】太原理工大学,山西太原030024;太原理工大学,山西太原030024【正文语种】中文【中图分类】TG439.1随着钎焊技术的不断发展，为了确保热处理过程中其设备的高温控制精度和温度场均匀性，国内很多企业对温度范围为150～350℃热处理设备提出使用AMS2750E的测试标准的要求。

在该温度范围内，由于辐射具有加热缓慢、温差小、吸热快、散热慢的特点，使得真空设备内的温度场很难达到热平衡，难以实现AMS2750E的测试标准的要求。

本文介绍了通过在真空焊接设备的设计中，考虑温度场因素，实现AMS2750E（温度范围150～350℃）标准下真空炉炉温均匀性的要求。

1.1 基本概念温度均匀性：在鉴定合格的真空焊接设备的工作区内，各测试点的温度相对于控制设定点温度的偏差（通常以±℃来表示）。

温度均匀性指标主要反应热处理设备在温度设定点，在设备工作区内温度一致性问题。

温度均匀性测试（TUS）：在热平衡前后，用校验过的仪器装置及传感器对热处理炉工作区温度变化量进行的一个或一系列测试。

1.2 AMS2750E对温度均匀性要求（1）温度传感器必须符合要求。

控温热电偶、报警热电偶、均匀性测试热电偶校准值必须在允许误差范围以内，可参照AMS2750E具体要求。

AMS 2750E高温测定法5 年一次的更新，复查并重审了该规范以提高其使用量，技术革新导致了使用的变化。
