Document record
The file is the guide specification for the PAC-3000 CS and PAC-3000 RS aluminum composite panels, dated October 2019 and supplied as a Word document. It is written as Section 07420 for aluminum composite material building panels and follows the usual specification order: summary, related documents, related work, performance requirements, quality assurance and references.
The performance section lists the tests the panel system must meet. These include ASTM E330 structural testing at a design pressure of 60 psf with a maximum span deflection of L/60, ASTM E283 air infiltration of no more than 0.06 cfm per square foot at 1.57 psf, ASTM E331 static water penetration between 6.24 psf and 12.0 psf, and AAMA 501 dynamic water penetration at 10.00 psf. It also sets a temperature change range of 120 deg F ambient and 180 deg F at material surfaces, and a substructure tolerance of +0 to -1/8 inch.
The quality assurance section covers manufacturer and installer experience, a recommended single source for fabrication and installation, and a maximum alignment deviation of 1/4 inch in 20 feet. It also recommends shop-installed aluminum stiffeners on all panels of 20 square feet or larger. The reference list names ASTM E330, E283, E331, E84, D1781, D3363, D2794, D3359 and D2247.
