... 3.2 FLOW NUMBER AND FLOW TIME Fn and Ft test methods are presented in NCHRP Report 465. Test methods adapted for the simple performance tester developed in NCHRP Project 9-29, "Simple Performance Tester for Superpave Mix Design," are presented in Appendix D of NCHRP Report 513: Simple Performance Tester for Superpave Mix Design: First-Article Development and Evaluation, which is available online at http://gulliver.trb.org/ publications/nchrp/nchrp_rpt_513.pdf.

From page 7...
... Thin and fully lubricated membranes at the test specimen ends were used to warrant frictionless surface conditions. All tests were conducted within an environmentally controlled chamber throughout the testing sequence (i.e., temperature was held constant within the chamber to ±1oF throughout the entire test)
