15.2. Batten Seam Roof Panel Test

Report Number: C.C.L. Performance Test Report #91-9218

Report Date: 26 September 1991

Introduction

A Mock-Up Test Specimen consisted of a 16 oz. copper, cold rolled temper, 1 ½" high batten seam roof section, sloped to a 4" in 12" pitch. The specimen was tested in accordance with SMACNA Roof Panel Test clarifications at the direction of SMACNA. The following text is an abbreviated description of the testing procedures, refer to original document for a complete report.

Test Date: 28 August 1991

Preload - Prior to testing, the specimen was subjected to a positive static pressure differential of 26.0 p.s.f., 50% of the assumed design load. The load was maintained for 10 seconds then released. No visible deformation or damage was observed in the specimen after the load was released.

Test Date: 23 September 1991

Air Infiltration Test Similar to ASTM E283-84 - The exterior face of the specimen was covered with an impervious visqueen material and sealed at the edges and corners. The complete perimeter joint (specimen to chamber) was taped over to eliminate this joint from the test specimen. A positive static pressure differential of 5.20 p.s.f. was applied to the face of the specimen and chamber. The measured amount of air infiltration through the chamber was 52.0 c.f.m. The impervious material was removed and the same test was performed and measured for gross air infiltration at the rate of 66.5 c.f.m. The net amount of air infiltration through the specimen was the difference between the specimen with the impervious material (chamber only) and the specimen without it.

Net Air Infiltration: 14.5 c.f.m.

Air Exfiltration Test Similar E283-84 - The exterior face of the specimen was covered with an impervious visqueen material and sealed at the edges and corners. The complete perimeter joint (specimen and chamber) was taped over to eliminate this joint from the test specimen. A negative static pressure differential of 5.20 p.s.f. was applied to the face of the specimen. Upon achieving a negative pressure of 5.0 p.s.f. the tape covering the perimeter joint lost adhesion.

Net Air Exfiltration: No results.

Static Water Penetration Test Similar to ASTM E331-86 - Water was applied with complete and continuous coverage to the exterior face panel of the test specimen, at a minimum rate of five gallons per hour, per square foot. Simultaneously, a negative static pressure differential of 10.4 p.s.f. (from below the roof) was applied against the face. The combined application of water and pressure was maintained for a period of 15 minutes.

RESULTS: Specimen passed the test. No "uncontrolled" water penetration was observed during or at the conclusion of test.

Dynamic Water Penetration Test Similar to AAMA 501.1-83 - Water was applied with complete and continuous coverage to the exterior face panel of the test specimen, at a minimum rate of five gallons per hour, per square foot. Simultaneously, the panel was subjected to an 80-85 m.p.h. slipstream airflow generated by a device situated approximately 20 feet away from the eave in front of the specimen. The combined application of water and wind was maintained for a period of 15 minutes.

RESULTS: Specimen passed the test. No water penetration was observed during or at the conclusion of test.

Uniform Structural Deflection Test - Dial indicator gauges were installed to measure deflection and residual deformation of the metal roof panel. The test was performed for both negative and positive static pressure of 26.0 p.s.f., equal to 50% of assumed design load. The load was held for ten seconds then released. The same test was performed for both conditions with a static pressure of 40 p.s.f., 60 p.s.f., and 90 p.s.f. Additional tests were performed in the positive mode for 90p.s.f., 125.0 p.s.f., and 150.0 p.s.f. Dial indicators were set to zero before each new load was applied.

RESULTS: Specimen passed the test. No deformation or damage was observed.
