ANSI/AWI 1232-2022 - Manufactured Wood Casework
3.3.1 Product Performance Requirements
a) /supplier’s documented fabrication methodologies shall include joinery, material, and component details that have been tested in conformance with AWI Test Methodologies referenced within this standard. Testing shall be conducted by laboratories holding ISO 17025 accreditation or operating under an equivalent quality management system recognized by AWI.
b) In the absence of testing, manufacturer/supplier may defer to AWI’s Tested and Approved Methods and Materials for Casework Construction, available at www.awinet.org/standards
c) Load values expressed within this standard are specific to referenced laboratory tests conducted in accordance with AWI Test Methodologies. These load values do not suggest service loads nor shall they be construed as suggesting normal casework usage loads.
d) Construction methods and materials shall be consistent throughout the project.
e) s which will receive sinks or appliances may be modified as needed, provided structural integrity is retained.
3.2.4 Shelves
a) Manufacturer/supplier shall provide documented instructions for Product installation. In the absence of documented instructions, casework installation shall defer to AWI’s Casework Installation Guidelines (available for download at Click Here ).
b) Installation of Product shall be in accordance with ANSI/AWI 0620 – Finish Carpentry/Installation (latest edition).
c) Manufacturer/supplier shall provide drawings indicating location of blocking. See AWI 100 – Submittals (latest edition).
d) Manufacturer/supplier shall provide documented instructions for the fastening methods of adjacent cabinets. Documented instructions shall include fastener details.
3.3.2 Determination of Product Performance Duty Level
a) Product Performance Duty Level is determined by the lowest tested value derived from AWI Test Methodologies referenced within this standard for joinery methods and materials or components. (Example: A Product may include a construction meeting Performance Duty Level 2 and may also include an adjustable shelf meeting Performance Duty Level 1. The assembled casework unit would then meet Performance Duty Level 1 as the lowest tested value.)
