Lays down detailed specifications for the instrumentation and procedure to be used for fixed temperature sensitivity testing. Applies to rectilinear pick-ups. Is applicable for the following parameters: frequency range: 20 Hz to 1250 Hz; dynamic range: 0,1 µm to 10 mm (frequency-dependent), 1 mm/s to 1 m/s (frequency-dependent), 10 m/s^2 to 1000 m/s^2 (frequency-dependent); temperature range: - 45 °C to + 800 °C. The uncertainty applicable is ± 10 % of reading.
