ANSI/AWI 0622.0646–2024 - Millwork & Wood Trim
3.1 General
a) The following requirements shall govern unless a project’s contract documents require otherwise.
b) Should a conflict be discovered within this standard, the least restrictive requirement shall prevail.
c) Manufacturer/supplier shall provide drawings in accordance with AWI 100 Submittals (latest edition).
d) When applicable, manufacturer/supplier shall verify field measurements.
e) Unless otherwise indicated, requirements apply equally to all aesthetic grades.
f) Any term used herein that is defined by the AWI Glossary uses only that definition for conformance to this standard.
g) When multiple options for wood species and/or trim profiles are permitted, selection shall be at the option of the manufacturer/supplier
3.1.1 Measurements
a) This standard is written with the International System of Units (SI) followed by the United States customary system of measurement in brackets.
b) The system of measurement used in the project’s original contract documents and architectural drawings shall dictate which system of measurement within these standards is used for verification of compliance.
c) The United States customary measurement is typically a “soft” conversion of the SI measurement. In order to make the SI number more conceptually coherent and consistent, most conversions for less than 152.4 mm [6”] in dimension are “soft” converted to the nearest 0.1 mm. For measurements above 152.4 mm [6”], the “soft” value is converted to the nearest 1 mm.
d) “Inconspicuous,” when used in this standard, means not readily visible without careful inspection at a distance of:
Premium | Custom | Economy |
---|---|---|
610 mm [24”] | 1219 mm [48”] | 1829 mm [72”] |
e) Gaps and flushness between components shall be tested with a feeler gauge at points where components are required to contact as indicated within this standard.
3.1.2 Special Requirements
a) When seismic construction is required, such requirements and details shall be specified in the contract documents.
b) Requirements, such as moisture resistant or fire-retardant materials, shall be specified in the contract documents.
3.1.3 Environmental Conditions
a) Requirements of this standard are contingent upon maintaining proper interior environmental controls prior to, during, and after installation. See AWI 200 – Care and Storage (latest edition).
b) Dimensional and warp requirements, flushness and gap tolerances of this standard are contingent upon maintaining proper interior environmental controls prior to, during, and after installation.
c) This standard does not establish grade requirements for dimensional, warp, flushness, and gap tolerances of Product intended for non-climate-controlled environments.
d) At time of jobsite delivery, dimensional, warp, flushness, and gap tolerances shall meet the requirements established herein. Post-delivery, such requirements no longer apply for Product intended for non-climate-controlled environments.
3.1.4 Manufacturer/Supplier Requirements for Installation
a) Installation of Product shall be in accordance with ANSI/AWI 0620 – Finish Carpentry/ Installation (latest edition).
b) Manufacturer/supplier shall provide drawings indicating required location of blocking. See AWI 100 – Submittals (latest edition).
3.1.5 Default Performance Requirements
a) Product shall comply with the following minimum defaults:
- Custom Grade
- Unfinished closed-grain hardwood intended for an opaque finish
