Does it pass or fail? A Conversation about Quality Control Testing Criteria
February 4, 2021 @ 1:00 PM - 2:00 PM
The material is applied, the air barrier is complete, and now all you need is to pass the field quality assurance testing. The air barrier adhesion test is performed and then comes the question: what is the pass/fail criteria? Is it the published number under “material properties” on the manufacturer’s data sheet? Is the ABAA required minimum? Is there a different standard written in the specification? Does a 1 psi difference really matter? This discussion can frequently become a point of contention on the job site at a point when a “fix” is expensive and time consuming for many. This session will be a conversation between a manufacturer and a consultant (with additional input from a contractor and auditor) about what really should be the prevailing criteria. It will include a discussion about what the published data means, how lab data compares to that found by testing in the field and what is required during an ABAA audit. Field application parameters based on the material testing criteria that are critical to the air barrier performance will be discussed. Insights from ABAA auditors will be shared about how to avoid this fight in the field and lessons will be shared. The entire conversation will be had around the premise of ensuring a well-installed, durable air barrier system without putting undo pressure onto installers by requiring them to meet unrealistic requirements.
- Describe the ABAA air barrier quality control requirements.
- Asses the difference between field testing data and what may be published on a manufacturers’ data sheet.
- Contrast differences between material testing standards and actual field installation conditions and the impact to air barrier performance.
- Evaluate what will be acceptable pass/fail criteria for a given product before it is tested.
