ASTM-E 1399 is a relatively new code that stipulates that all expansion and seismic joint cover systems be tested through 500 movement cycles and remain functional. Since these covers are intended to move in this way, specifying ASTM-E 1399 is simply a quality assurance for your client. In the case of fire barrier testing, UL 2079 stipulates that the assembly must be cycled 500 times prior to testing. A critical quality assurance factor ensuring peace of mind for your client.
