2.4 Order of precedence. In the event of a conflict between the text of this document and the references cited
herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws
and regulations unless a specific exemption has been obtained.
3. REQUIREMENTS
3.1 First article. When specified (see 6.2), a sample shall be subjected to first article inspection in accordance
with 4.2.
3.2 Materials. Cast iron shall not be used in the fan-coil unit nor shall cast iron be used in motors, which are
components of the fan. Gray cast iron may be used for the fan and motor sheaves. Materials for fan-coil units shall
be corrosion resisting or material shall be protected against corrosion after fabrication. Material degraded during the
fabrication process shall be normalized to restore those properties before assembled in any fan-coil unit. Selected
materials shall be capable of meeting all of the operational and environmental requirements specified herein.
3.2.1 Hazardous material. Materials for use in the construction of fan-coil units shall have no effect on the
health of personnel when the materials are used for intended purpose. Regardless of other requirements, materials
and parts containing asbestos, cadmium, lithium, mercury, or radioactive material shall not be used.
3.2.2 Fasteners. Material for all bolts, nuts, studs, screws and similar fasteners shall be corrosion-resistant
passivated or of a material rendered resistant to corrosion and meet requirements of ASTM A307. Sheet metal
screws shall not be used. Galling shall be prevented. Tapped holes shall be reinforced where shearing of thread can
occur.
