WDMA issues Technical Bulletins to address formal requests relating to the content of or compliance with existing standards. Technical Interpretations apply to specific editions of standards, and are intended to be incorporated into the next revision of the standard when it is developed. WDMA Technical Interpretations undergo formal review and approval following procedures established within the WDMA Technical Committee Handbook, and may also be issued jointly in cooperation with other sponsoring organizations.
Below are the current Technical Interpretations that apply to WDMA standards:
