1.1 本试验方法涵盖了对用于热处理钢制品的炉进行温度均匀性调查的程序。该方法用于确定熔炉满足适用产品规范中规定的或经买方和热处理服务供应商同意的允许温度变化的能力。本试验方法中定义了测量文件要求以及随后用于建立熔炉工作区的程序。 1.2 本试验方法涵盖以下任何类别的热处理炉: 1.2.1 连续或半连续输送炉， 1.2.2 间歇炉，以及 1.2.3 盐或液体浴和流化床。 1.3 本试验方法仅适用于产品规范或采购订单中规定的情况。 1.4 使用连接到每个负载末端的热电偶控制钢制品的热处理是执行炉调查的替代方法。生产商应遵守 附件A1 . 1.5 通过买方和热处理服务供应商之间的相互协议，可以规定更严格和/或附加的要求。任何此类附加要求的接受应取决于与供应商的谈判，并且必须包含在买方和供应商商定的订单中。 1.6 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值； 因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.7 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 1.8 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 钢制品热处理炉在许多行业以多种方式使用。无论热处理炉类型或加工周期如何，用户都可能需要了解炉内的温度均匀性，以及材料是否在炉内能够满足适用允许温度变化要求的区域内加工。 4.2 本试验方法中的程序可供用于加工钢产品的热处理炉的使用、制造和提供校准服务的人员使用。

1.1 This test method covers the procedures used to conduct a temperature uniformity survey on a furnace used to heat treat steel products. This method is used to determine the capability of the furnace to meet the permissible temperature variation specified in the applicable product specification, or as agreed to by the purchaser and supplier of heat treat services. Survey documentation requirements, and the procedure used to subsequently establish the furnace working zone, are defined in this test method. 1.2 This test method covers heat treat furnaces in any of the following categories: 1.2.1 Continuous or semi-continuous conveyance furnaces, 1.2.2 Batch furnaces, and 1.2.3 Salt or liquid baths and fluidized beds. 1.3 This test method only applies when specified in the product specification or the purchase order. 1.4 Controlling a heat treatment of steel products using thermocouples attached to the extremities of each load is an alternative to performing a furnace survey. The producer shall adhere to Annex A1 . 1.5 By mutual agreement between the purchaser and the supplier of heat treat services, more stringent and/or additional requirements may be specified. The acceptance of any such additional requirements shall be dependent on negotiations with the supplier and must be included in the order as agreed upon by the purchaser and supplier. 1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.7 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. 1.8 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. ====== Significance And Use ====== 4.1 Furnaces for heat treatment of steel products are used in many industries, in many ways. Regardless of heat treat furnace type, or processing cycle, it may be necessary for users to know the temperature uniformity in the furnace and whether the material is processed in a zone within the furnace that is capable of meeting the applicable permissible temperature variation requirements. 4.2 The procedures in this test method may be used by those using, manufacturing, and providing calibration service for, heat treat furnaces used to process steel products.
