ICS CCS National Standard of the People's Republic of China ‌GB/T 6011-2026 Test method for flammability characteristics of fiber reinforced plastics - Incandescent rod method 纤维增强塑料燃烧性能试验方法 炽热棒法 Issue date: 2026-01-28 Implementation date: 2027-02-01 Issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China the Standardization Administration of the People's Republic of China Contents Foreword 1 Scope 2 Normative References 3 Terms and Definitions 4 Principle 5 Testing Equipment and Instruments 6 Test Specimen 7 Test Procedure 8 Calculation 9 Test Results 10 Test Report Test method for burning behaviour of fibre reinforced plastics — Hot rod method 1 Scope This document specifies the principle, testing equipment and instruments, test specimen, test procedure, calculation, test results and test report for the determination of the burning behaviour of fibre reinforced plastics using the hot rod method. This document is applicable for assessing the burning behaviour of fibre reinforced plastics under the conditions specified in this document, but is not applicable for assessing fire hazard under actual use conditions. 2 Normative References The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition (including any amendments) applies. GB/T 1446, General principles for test methods of properties of fibre reinforced plastics 3 Terms and Definitions No terms and definitions need to be defined in this document. 4 Principle The test specimen is brought into contact with a hot rod at a constant temperature under a specified contact force. After the specified contact time, the burning time, burn length and mass change of the specimen are determined. 5 Testing Equipment and Instruments 5.1 Ventilation System The test shall be carried out in a ventilation system equipped with an observation window. 5.2 Hot Rod Test Apparatus 5.2.1 Equipment structure The hot rod test apparatus includes key components such as a specimen holder, a hot rod, an insulating support, a counterweight, a stop screw, a positioning rod and other auxiliary components. A schematic diagram of the structure is shown in Figure 1. 5.2.2 Specimen holder Mounted on a vertical, movable column to secure the test specimen. 5.2.3 Hot rod Made of silicon carbide, with a diameter of 8 mm and an effective length of 100 mm. The hot rod may be heated using alternating or direct current to stabilise it at (955 ± 10) °C. This temperature may be calibrated using 99.8 % pure silver foil (melting point 955 °C) with a thickness of 0.06 mm. 5.2.4 Insulating support Made of ceramic, asbestos or other heat-resistant insulating material to hold the hot rod. This support is mounted on a base plate and can rotate about a horizontal shaft fixed on two bearings, allowing the hot rod to move away from or into contact with the test specimen. 5.2.5 Counterweight and stop screw The counterweight shall enable the contact force between the hot rod and the end face of the test specimen to be approximately 0.3 N. The stop screw and gasket shall stop the hot rod after the test specimen has burned away 5 mm during the test. 5.2.6 Positioning rod A metal rod with a diameter of 8 mm. Used to adjust the position of the test specimen before testing in place of the hot rod. 5.3 Timer Measuring accuracy of 0.1 s. 5.4 Vernier calliper Measuring accuracy of 0.01 mm. 5.5 Analytical balance Measuring accuracy of 0.1 mg.
