Introduction

Code Corner by Patrick J. WelchThis column is intended to discuss new or existing rules and interpretations that may affect the operations or planning of your vertical transportation systems. The rules within the A17.1 Code are intended to be clear and unambiguous, but there are sometimes unintended consequences to the rules that leave the reader confused as to the intention of the Code.

Each subcommittee of A17.1 addresses interpretations at their regular meetings to help assure a prompt and responsive clarification. This is particularly important when new rules come out each year; it is not unheard of for a rule to confuse either a designer or an inspector within a jurisdiction trying to figure out what the intent of a new rule was.

I encourage anyone with a question to a particular requirement's meaning to contact me directly, or write to ASME A17.1 requesting a formal interpretation. The format for the inquiry is clearly stated in the first section of A17.1.

There are a few important issues to understand:

  1. A new rule is always intended to be clear and precise, but can fall short.
  2. The subcommittee gets the request for interpretation from the Standards Committee and is charged with investigation and to propose a response.
  3. The Standards Committee makes the ultimate decision, not the subcommittee.
  4. Check previous interpretations for potential resolutions brought by others before you.
  5. Finally, request an interpretation yourself if you cannot determine the intent of a particular rule.
