BS 3231 is an International Standard that discusses the technical specifications for thermographs (Bimetallic type).
BS 3231 relates to thermographs of the bimetallic type, for general and marine which are used in obtaining a continuous record of air temperatures within the range 0 °F to 140 °F (– 20 °C to 60 °C).
The instrument described in BS 3231 comprises a bimetallic element, the response of which to temperature changes controls the movement of a pen, and a clock-driven drum that carries a chart on which the pen movement records against a temperature scale.
BS 3231 on specification for thermographs is useful for:
Thermograph is an instrument that produces a trace or image representing a record of the varying temperature or infrared radiation over an area or during a period, protection, insulation and lifetime.
BS 3231 discusses materials, design and construction that depict a user-friendly idea of thermographs. BS 3231 also provides you with test methods to verify the performance characteristics of thermographs which ensures their reliability.
BS 3231 discusses the specifications for marking and packaging details about the thermographs that help users to manufacture good quality products.
