ANSI ASC A14.5-2007
American National Standards for Ladders - Portable Reinforced Plastic - Safety Requirements
This standard prescribes rules governing the safe construction, design, testing, care and use of portable reinforced plastic ladders of various Types and styles. Ladder Types included are:
| Duty Rating | Ladder Type | Working Load (pounds) |
| Special Duty | IAA | 375 |
| Extra Heavy-Duty | IA | 300 |
| Heavy-Duty | I | 250 |
| Medium-Duty | II | 225 |

Note: Ladder type step stools are covered by A14.5. It is recognized that a step stool standard is under development. When the step stool standard is approved, A14.5 will no longer cover ladder type step stools.
These requirements are also intended to prescribe rules and criteria for labeling/marking of the kinds of portable ladders cited in this standard, but exclusive of furniture type step stools and special purpose ladders. These labeling/marking requirements do not apply to those situations where training, supervision, or documented safety procedures would be in conflict, or serve in lieu of, these labeling/marking requirements.
