1. Rationale
Specifying the time constant for the furnace thermocouples is not a practical requirement for most testing laboratories and they are often use the (Note 2) as the guide for their own thermocouple design. Note 2 also, specifies standard weight nominal in. iron, steel, or Inconel but without specifying either the pipe thickness or sealed end thickness. The pipe outside diameter and wall thickness as well as the thickness of the sealed end are important factors in harmonization of furnace temperature measurements. In the ISO 834 and Canadian CAN/ULC-S101 standards on fire resistance, the specification for the thermocouples or thermometers is clearly defined. It is proposed in this ballot to drop the reference to time constant in subsection 6, as well as Note 2 and its reference in subsection 6 in standard E119 on fire resistance.
