1.02 Testing and Performance Requirements

A.  Test Procedures and Performances

1.  Air Infiltration Test: With access door closed, test unit in accordance with ASTM E 283 at a static air pressure water column (WC) difference of 1” WC (5.2 psf) through 5” WC (26.0 psf) in increments of 1”, and a test at 10” WC (52.1 psf) and 15” WC (78.1psf).

a.  Air infiltration shall not exceed 0.10 cfm at any of the test pressures.

2.  Water Resistance Test: With access door closed, test unit in accordance with ASTM E 331 at a static air pressure difference of 2” WC (10.4 psf) and 4” WC (20.8 psf).

a.  There shall be no uncontrolled water leakage.

1.03 Warranties

A.  Total Access Door System: The responsible contractor shall assume full responsibility and warrant for one (1) year the satisfactory performance of the total access door installation.

2.01  Materials

A.  Aluminum: Extruded aluminum shall be 6063-T5 or T6 alloy and temper. All aluminum mounting frame extrusions shall have a minimum wall thickness of .080” and all door panel extrusions shall have a minimum wall thickness of .060”.

B.  Hardware: Locking handles shall be [specify handle model and manufacturer]. Manufacturer’s standard lock quantity for access door width and height shall be used. Each access door shall have [one continuous butt hinge or the manufacturer’s recommended number of 10” butt hinges] Series 304 stainless.

C.  Primary Weather Strip: All primary weather-strip shall be a continuous, 3/8” diameter, extruded Santoprene cord set into an extruded aluminum raceway.

D.  Secondary Weather Strip [only if required for improved air infiltration performance]: Factory apply an extruded Santoprene bulb with PSA on one side of a flat mounting fin to all four sides of the mounting frame.

E.  View Port: Factory install extruded aluminum view port in the specified access doors locations. View port day light opening size shall be as follows: [specify 8” x 8”, 8” x 12” or 12” x 12”]. [Insulated glazing shall be as follows: ¼” clear wire exterior / ¼” clear tempered interior. OR Single glazing shall be as follows: ¼” clear wire exterior]

G.  Door Panel Skins

1.  Interior skin: [Specify skin]

2.  Exterior skin: [Specify skin]

H.  Thermal Brake Frame [May be required for improved U value and condensation resistance]. The perimeter mounting frame and door panel thermal barrier shall be poured and debridged thermal barrier made of two-part polyurethane. The mounting frame extrusion shall have a mechanically staked system consisting of alternating aluminum cleats no more than one inch on center along the thermal barrier pocket to minimize the effects of thermal barrier dry shrinkage.

2.02 Fabrication

A.  General: Depth of access door panel from skin-to-skin shall not be less than 2”.

B.  Finish

1.  All aluminum extrusions and metal skins shall remain mill finish.

OR
