4 Fire Test 4.1 General 4.1.1 Procedures The supplier/manufacturer shall develop procedures for conducting the fire test. These procedures shall be documented and included in the final report of the results. The procedures shall include pre- and post-test inspection activities and identify critical areas to be inspected. The supplier/manufacturer shall document all test parameters and results of the evaluations that demonstrate conformance to this document. Fire testing shall be discontinued if the product or system fails to perform within the limits specified, except when such failure is determined to be the result of a failure within the test facility or test fixture and that failure and its correction do not affect the validity of the test results. 4.1.2 Personnel A qualified person shall conduct preparation, testing, and approval of results. 4.1.3 Measuring and Monitoring Equipment Measuring and monitoring equipment used during the testing process shall be calibrated in accordance with the requirements of the supplier/manufacturer or test facility. Measuring and monitoring equipment shall be used within its calibrated range. All pressures are defined as gauge pressure unless otherwise specified and shall be recorded on time-based equipment. Leakage rates shall be in milliliters per inch of nominal valve size per minute (milliliters per millimeter of nominal valve size per minute), averaged over the duration of the particular test period.4.1.4 Test Report A test report shall be prepared for each test. It shall be approved by a qualified person and retained as part of the design validation records for the product. The report shall include, at a minimum, the following information: — validation test performed, — description of the tested item, including size, type, model, unique identifier, and metallic and nonmetallic materials, — data perAnnexA, if applicable, — test facility name, location, and person performing the testing, — date of testing conducted, — test schematic or photos, — procedures used, records of results, and discussion of those results, — results of specific pre- and post-test evaluations, — summary of results, including a discussion of whether the test was successful, — approvals and date of the report.NOTE Records may be electronic or hardcopy. 4.1.5 Previous Fire tests Fire testing that has been completed and documented in accordance with requirements of previous editions of API 6FA and 6FD during their validity shall be acceptable in meeting the requirements of this standard. 4.2 Test Valve 4.2.1 General The test valve shall conform to the applicable API product specification prior to the start of this fire test. Except for check valves, the test valve shall include a port for the exclusive use of the relief valve (item 15 in Figure 1) to relieve the center cavity pressure to the atmosphere to protect against potential rupture of the valve. For check valves, a bypass line shall be included (item 21 in Figure 1). NOTE Any integral external pressure relief is in addition to the test port described above. 4.2.2 Symmetry Limitation Valves with asymmetric seat or body sealing systems intended for bidirectional installation shall be qualified by testing in both directions.NOTE The same valve may be refurbished and retested, or another, identical, valve may be tested in the other direction.API Std 6FA pdf download.
