ANS Process: Key Steps and Quick References

ANSI’s “ANS Key Steps” document (www.ansi.org/anskeysteps) provides a rundown of the major steps involved in the approval of voluntary consensus standards as American National Standards (ANS). The document includes helpful embedded links that provide immediate access to relevant forms and additional information.

ANSI facilitates ANS development through its accreditation of the procedures of participating standards developing organizations (SDOs). To qualify for ANSI accreditation, organizations must meet the Institute’s requirements for openness, balance, due process, and consensus in their standards development processes as set-forth in the ANSI Essential Requirements (www.ansi.org/essentialrequirements).

Organizations must undergo an application process, which includes a public review of procedures and be designated as ANSI-Accredited Standards Developers by the ANSI Executive Standards Council (ExSC) before any of their voluntary consensus standards can be considered for ANS status.

 List of ANSI-Accredited Standards Developers.


Major parts of the ANS process include:

  • Consensus by a group that is open to all interested parties
  • Broad-based public review, including via ANSI Standards Action (www.ansi.org/standardsaction)
  • Incorporation of proposed changes that meet consensus requirements into a draft standard
  • The availability of a procedural appeals process

Once approved as an ANS, a standard must be maintained on a regular basis and is subject to the ANSI audit process.
