Standard Practice for Determining Surface Temperature of Molds for Plastics 确定塑料模具表面温度的标准实践
发布日期: 2021-01-01
1.1 本规程旨在确定塑料模具型腔和基座表面上一个或多个指定点的温度。通过在认为必要的多个点上确定温度,可以确定表面的整体温度条件。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 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、健康和环境实践,并确定监管限制的适用性。 注1: 没有已知的ISO等效于本标准。 1.4 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====== 3.1 模具的温度会影响模制零件的性能和制作满意试样的难易程度。希望了解实际模具温度,其可能不同于模具温度控制介质。 3.2 用户需要了解模具/热电偶接口和导线处的温差,并采取适当的预防措施,将此类温差降至最低。
1.1 This practice is intended for determining the temperature at a specified point or points on the surface of the cavity and base of a mold for plastics. By determining the temperature at as many points as deemed necessary, the overall temperature condition of the surface can be determined. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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. Note 1: There is no known ISO equivalent to this standard. 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. ====== Significance And Use ====== 3.1 The properties of molded parts and the ease of producing satisfactory specimens are influenced by the temperature of the mold. It is desirable to know the actual mold temperature, which can differ from the mold temperature control medium. 3.2 The user needs to be aware of temperature differences across the mold/thermocouple interface and at leads, and take appropriate precautions to minimize such differences.
