ANSI / WMA 100
World Millwork Alliance is a standards-developing organization accredited by the American National Standards Institute (ANSI). In 2009, we developed the WMA 100, a proactive and voluntary performance standard for side-hinged exterior doors (SHEDs).
What is the ANSI/WMA 100 Standard for Side-Hinged Exterior Doors?
- Approved as an American National Standard by ANSI
- Uses the ASTM E330 test method to obtain a full system design pressure rating
- Defines methods for qualifying door system components for substitution in the rated system
- Outlines slab stiffness testing procedures for use in determining component substitution
How Does the ANSI/WMA 100 Benefit My Business?
- It is fair, accurate, and reliable
- It can be used to meet testing and labeling wind load requirements in the International Residential Code (IRC)
- It provides procedures for component qualification and substitution, which makes it cost-effective for door pre-hangers as it limits the amount of testing required
As an ANSI accredited Standards Developing Organization (SDO), WMA maintains the standard pursuant to ANSI requirements as reflected in the Procedures for the Development, Revision, Withdrawal, and Discontinuance of WMA Standards.

WMA 100 Technical Interpretations: A Quick Guide
A technical interpretation is defined as a written explanation of the meaning of a specific provision of the standard as determined by either the WMA Interpretations Policy Committee (IPC) or by the WMA Director of Codes and Standards, in response to a written request. The requester shall decide whether to request an ‘official’ or ‘unofficial’ interpretation. See our Quick Guide below.
- Written request sent to email@example.com with the subject line: “Request for Unofficial Interpretation”
- Include requester phone number and email
- Result determined by WMA’s Director of Codes and Standards
- Response time: 10 days
Below are Interpretations issued by WMA’s Interpretations Policy Committee (IPC).
Please note that an interpretation shall not be used to change the content of the standard. Requests that are proposals for changes to the standard will be referred to WMA’s Industry Standards and Certification Committee (ISCC) for consideration in future standard revision cycles.
WMA 100 Revisions
WMA’s Voluntary Standard, ANSI/WMA 100-2016, “Standard Method of Determining Structural Performance Ratings of Side-Hinged Exterior Door Systems and Procedures for Component Substitution” is undergoing a 5-year revision cycle pursuant to ANSI’s periodic standard maintenance requirements.
Several revisions were proposed by WMA’s Industry Standards and Certification Committee (ISCC) and a public comment period was conducted in May/June to allow for the review and comment of the draft standard which incorporated these revisions.
In July/August, the ISCC made additional revisions to the draft standard based on comments received from the WMA Consensus Body, which is the voting committee of interested parties that also reviewed, commented, and voted on the draft in June.
These additional revisions are available for review and public comment until October 1, 2017, and they can be accessed here. Comments for this recirculation should be emailed to Jessica Ferris, Director of Codes and Standards.
