SECTION 12. Calibration of
Measuring Devices
It is recommended that all equipment used for timing, measuring wind,
weighing and measuring implements, and measuring performance be certified for
accuracy by an appropriate testing agency in accordance with methods specified
by the manufacturer, before the first competition each year and preferably before
each major competition, to comply with Rules 6-1.12 and 6-1.15.
Verification of the accuracy of devices used to measure distance can be
accomplished by comparison to an available surveyed distance.
