American National Standard (ASC) Safety Requirements for Ladder Accessories
This standard is for accessories used on individual
ladders only and prescribes rules for governing the safe
design, construction, and testing of accessories used in
conjunction with a portable wood, metal or reinforced
plastic ladder. This standard is limited to those
accessories specifically defined.
Devices which may or may not be an integral part of the
ladder, and without which the portable ladder cannot
function in its intended manner such as hinges and hinge
brackets, rung or step braces, locks and lock brackets,
spreaders and top caps are not included in this standard.
Replacement parts of essentially the same design and
construction as the component being replaced are not
included in this standard unless they are a component of
the accessory itself.
It is intended that all ladders employing accessories covered
by this standard comply with the requirements of the most
current applicable American National Standard Safety
Requirements For Portable Wood, Metal or Reinforced
Plastic, ANSI A14.1, A14.2, and A14.5 respectively.
