RULE 6 / FIELD EVENTS91
personal implement, provided it meets legal specifications. To determine this,
the games committee shall set a time and place, before the start of the event,
for inspecting, weighing and measuring all implements to be used in the meet
(warm-up and competition). Weighing and measuring devices must be capable
of certifying the implements within the allowable event specifications.
In the event an implement should become damaged during the course of the
competition, its use shall be permitted only after it has been reinspected and
approved.
A competitor may use another competitor’s implement during competition
only with the other competitor’s permission.
Competitors are not allowed in the impact area during warm-up or
competition. Implements shall be carried, not thrown, out of the sector by an
official.
Illegal Implements
ARTICLE 13. A field-event competitor shall be disqualified, and their marks
and/or points scored disallowed, if that competitor:
a. Uses an implement (shot, discus, javelin, hammer, weight or shoe) that has
been altered to become illegal after having been inspected officially;
b. Uses an implement that was not certified before competition; or
c. Brings an illegal implement into the competition or warm-up area.
Illegal Implements During Recertification
ARTICLE 14. If an implement is deemed illegal during recertification for
record purposes, marks achieved and points scored by the competitor will be
counted, even though the record will not be recognized.
Taking Measurements
ARTICLE 15. All measurements of height or distance may be made with a steel
tape, fiberglass tape, bar or electronic measuring device. Of these devices, only
the steel tape and electronic measuring device, calibrated according to Rule
2-12, are acceptable for record purposes.
When measuring the throwing events or horizontal jumps, that part of the
tape that records distance shall be read and announced by the official at the
circle, foul line or takeoff board. The tape should be pulled through the center
of the throwing circle, the radius of the throwing arc, or from a position 1
meter behind the takeoff board.
In the pole vault and high jump, measurement of the official height shall be
from a point on the same level as the takeoff to the lowest point on the upper
side of the crossbar.
