1EC Foreword
1) International Conference on Technology (IFC) Resolutions and agreements on technical issues are formulated by technical committees attended by representatives of national committees that are particularly interested in the issue. They express the international consensus on the issue as much as possible. 2! These resolutions or agreements are in the form of recommended standards. 3) In order to promote international unification, IEC hopes that national members will adopt the contents of IFC standards as their national standards within the scope of their agreement. Any inconsistencies between IFC standards and corresponding national standards should be pointed out in the national standards. This standard is prepared by the Technical Committee for Fire Hazard Tests. The following documents are used as the basis for the text of the standard. Draft International Standard

This standard adopts the following definitions:
Standardized test Flame conforms to this standard and meets all the requirements of Section 4. 4 Requirements
1: Standard water ignition is also produced in the following way:
Use the same as shown in Figures 1 to 3;
- Supply the internal gas with a purity greater than at a flow rate of 650mI./min±8nml./min at 23℃, 0.1MPa, and supply the air at a flow rate of 10mL/min±0.5mL/min at 23℃, 0.1MPa. The flame should be sufficiently symmetrical and stable, and the verification test results of 43 to 5s specified in 5.21 can be obtained. Note: The approximate size of the flame is: Approved by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China on July 12, 2001 and implemented on November 2, 2001. 5 Generation and verification of test flame 5.1 Generation GH/T5169.14—2001 173 cn--150 mo.
Use the burner gas supply device shown in Figure 7. Care should be taken to ensure that there is no leakage during operation: ignite the burner and adjust the gas and air flow rates to the specified values. The flame is symmetrical and stable when measured. 5.2 Verification
5.2.1 Quality
When the flame test device shown in Figure 8 is stopped, the time required for the temperature to rise from 0 to M as shown in the figure should be 455.
5.2.2 Procedure
In a ventilation environment, connect the device according to the figure to ensure that there is no gas and air leakage at the connection. When adjusting the gas and air flow rates, move the combustion group to avoid the flame snake. Ignite the gas and adjust the gas and air flow rates to the specified values. Ensure that the estimated height and total height of the blue flame center of the flame are within the specified range, and observe the flame growth under soft light. Wait for 5 minutes for the device to reach the effective condition. Make the temperature/time display/record set in operation and re-ignite the burner position under the copper block. Make 3 measurements to determine the time for the temperature to rise from 100°C ± 2T to 70°C ± 3°C. After each measurement, let the block cool to below 0°C in the air. If the block has never been used, run it first and then run it again, ignite the result. 5.2.3 Calculate the average time in seconds as the result. 5.2. If the flame is recognized and can be used for the test within 45a ± 55, 5.3 Gas and fuel 5.3.1 Burner The burner shall be manufactured according to Figures 1 to 5. In order to facilitate the clearing of the total combustible gas quality and the flame, it is necessary to disassemble it. 5.3.2 Flow rate: The flow meter should be:
suitable for measuring 23 (0.1M) gas with a flow rate of 650ml/min under the condition of 0.7m and an accuracy of -2%; suitable for measuring 2]c: 0.1MFa air with a downstream flow rate of 10L/min and an accuracy of -2%; 5.3.3 Long and small gauges
Two pressure gauges suitable for measuring 10~.7.5) kPa. A water pressure gauge can also be used, but the standard should be +10 (0-.7.) kPa. 5.3.4 Control nets
Two control gas and air flows are limited to the specified tolerance. 5.3.5 Block
In the case of complete machining but no drilling, the block diameter is Sm and the measurement is 10.09g (.g net) 5.9.6 Thermoelectric Regulator
The thermoelectric dummy has a sheathed pin (K) fine (NiCNiA) and the diameter is ma suitable for working at temperatures above 0.5.
The preferred method of fixing the thermocouple to the steel block is to use a squeeze block (see 3) on the thermoelectric block. , but the actual measurement is not available, 2
5.3.7 The time display/recording and timing device is suitable for the time of heating the block from 1UU±2 to 700℃ and the time measurement error is ±0.53:5.3.8 The instrument for measuring the atmospheric temperature and pressure is also required. 5.3.9 Gas - 98℃ 5.3.10 Air - Herbal and water-free.
6 Recommended equipment for using test flame
The principles for selecting suitable test equipment are given in GB/T516S.7. The test equipment example in Appendix 4 gives the distance between the test tube and the sample surface. The distance between the test tube and the sample surface is 109mm. The method is to select the flame tip of the test tube and the test sample according to the method of the test chamber. The test instrument should be properly calibrated and the test sample should be properly calibrated. The test sample and the residual method under the test condition will not burn the test sample. The instrument can be named as 1k nominal test flame in accordance with the technical requirements of this standard. It is in accordance with GB/T5169.14. Note: 1.231, 1 in the loan vehicle, if the single need, special rate parts, 5 Figures are kept together, with the group of gas-free products: pregnancy, and 5 overall manufacturing to use a common method to fix together, and no gas will occur.
