Shall not be in such condition as to impair their structural strength. Those having cracks that do not affect
their strength are acceptable. Wood will crack and check from natural causes without necessarily having
its strength impaired.
*It is impossible to provide specific standards for some items. In these cases, reliance is placed on the inspector's experience with
identical or similar equipment. His judgement must be based on willingness to accept or reject equipment in like condition for the
