BS EN 16465:2015规定了黑色标准温度计(BST)的可追溯校准方法,
白色标准温度计(WST)、黑色面板温度计(BPT)和白色面板温度计
(WPT)用于自然和人工风化:方法A,接触法,使用可追溯的校准电阻标准温度计;方法B是一种非接触式方法,使用可追踪的校准高温计。EN ISO 4892-1中描述了温度计类型的基本设计。注1:历史上,方法A已用于风化应用多年:
方法B已被采用
最近发展起来的。这两种方法都适用于风化应用。它们可能提供不同的服务
不可互换的校准结果。注2:附录A给出了BST/WST和BPT/WPT的特性信息。交叉引用:EN ISO 291ISO 291EN ISO 4892-1ISO 4892-1ASTM G179购买本文件时可获得的所有现行修订均包含在购买本文件中。
BS EN 16465:2015 specifies traceable calibration methods of black-standard thermometers (BST),
white-standard thermometers (WST), black-panel thermometers (BPT) and white-panel thermometers
(WPT) for use in natural and artificial weathering:method A, a contact method, uses a traceable calibrated resistance standard thermometer;method B, a contactless method, uses a traceable calibrated pyrometer.A basic design of types of the thermometers is described in EN ISO 4892-1.NOTE 1 Historically method A has been used for weathering applications for many years: Method B has been
developed recently. Both methods are qualified for weathering applications. They may provide different
calibration results that are not interchangeable.NOTE 2 Annex A gives information on the characteristics of BST/WST and BPT/WPT.Cross References:EN ISO 291ISO 291EN ISO 4892-1ISO 4892-1ASTM G179All current amendments available at time of purchase are included with the purchase of this document.
