Appendices
A Information to be supplied by purchaser
B Method of measuring operating temperature
Specifies fixed and adjustable capacitors for railways signalling track-circuits, and contains performance and dimensional requirements and includes sections giving routine and type tests. The capacitances (overall and intermediate values) are specified together with tolerances. Appendices give guidance on the method of measuring operating temperature and on the information that should accompany an order.
