ANSI Process

ANSI Process

ACCA is one of over a hundred organizations that develops standards and supports the American National Standards Institute (ANSI). ANSI approval of ACCA manuals, procedures and processes verifies that the principles of openness and due process have been followed in developing these materials, and that a consensus of those directly affected by the standards has been achieved.

ACCA’s ANSI standards activity is overseen by our Standards Task Team, which forms subcommittees as needed to oversee specific standards development. The process is open and you are encouraged to get involved; for more information, contact codes@acca.org.

CURRENT ACTIVITIES

Member Input Needed – ACCA Reviewing Several of its ANSI Recognized Standards for Potential Updates 

ACCA has begun the process to review several of its current standards that are recognized by the American National Standards Institute (ANSI).  According to ANSI’s Essential Requirements, once a standard is approved it must be reviewed every 5 years to determine whether it requires (a) additional changes or updates, (b) reaffirmation if no changes are needed, or (c) withdrawal. 

A description of each standard under review is shown below.

ANSI/ACCA 5 QI – 2015

ANSI/ACCA 5 QI – 2015, HVAC Quality Installation Specification

This standard details the nationally recognized minimum criteria for the proper installation of HVAC systems in residential and commercial applications.

ANSI/ACCA 6QR – 2015

ANSI/ACCA 6QR – 2015, Restoring the Cleanliness of an HVAC System

This standard establishes minimum requirements to restore the cleanliness of residential and commercial HVAC systems in accordance with manufacturer- or customer-specified criteria.

ANSI/ACCA 14

ANSI/ACCA 14, QMref – 2015, Quality Maintenance of Commercial Refrigeration Systems

This standard establishes a minimum maintenance program for maintaining refrigeration equipment found in supermarkets, convenience stores, food service, and warehouses, operating with saturated suction temperatures between -40°F and +40°F.

ANSI/ACCA 2 Manual J – 2016

ANSI/ACCA 2 Manual J – 2016, Residential Load Calculations

This manual produces HVAC equipment sizing loads for single-family detached homes, small multi-unit structures, condominiums, town houses, and manufactured homes.  A proper load calculation, performed in accordance with the Manual J 8th Edition procedure, is required by national building codes and most state and local jurisdictions.  Manual J8 provides detailed requirements for producing a residential load calculations per the CLF/CLTD method.

In conjunction with ACCA's review, if you have any changes or additions to offer on any of the above standards, please contact codes@acca.org.
