ADC Flexible Duct Performance & Installation Standards
The ADC has produced the 5th Edition of the
Flexible Duct Performance & Installation Standards
(a 28-page manual) for use and reference by designers, architects, engineers, contractors, installers and users for evaluating, selecting, specifying and properly installing flexible duct in heating and air conditioning systems.
Features covered in depth include: descriptions of typical styles, characteristics and requirements, testing, listing, reporting, certifying, packaging and product marking.
Guidelines for proper installation are treated and illustrated in depth, featuring connections, splices and proper support methods for flexible duct. A single and uniform method of making end connections and splices is graphically presented for both non-metallic and metallic with plain ends.
ADC Flexible Duct Test Code – FD 72-R1
This ADC 44-page
sets forth the specific methods of testing flexible air ducts used for indoor comfort heating, ventilating and air conditioning applications.
The scope of the code establishes the requirements for the determination and presentation of data on air friction loss, sound, leakage, heat transfer properties and static pressure-temperature behavior for flexible air ducting used as a means of conveying conditioned air in HVAC systems.
Requirements are established for the selection and preparation of test equipment and procedures to be used, the installation of test specimens and accumulation of test data and the format of presentation of the results.
