When undergoing ASTM E283 testing, you can expect the process to involve a thorough evaluation of your fenestration product’s air leakage performance under controlled pressure conditions. Initially, the testing team will ensure the specimen—such as a window, door, or curtain wall—is properly sealed and prepared according to standard guidelines. Specialized equipment will then apply specific positive and negative air pressures across the specimen while precisely measuring airflow rates. During testing, technicians carefully monitor the procedure to record accurate data, documenting any observed leaks or air infiltration points. Upon completion, you’ll receive a detailed report outlining the test results, highlighting whether the product complies with the required performance standards, and providing valuable insights for potential product improvements or certification purposes.
