GJB 5309 Test methods of initiating explosive devices consists of the following 38 parts: —Part 1: General principles; —Part 2: Leak test——Bubble method; —Part 3: Leak test——Helium gas method; —Part 4: Measurement of bridge circuit DC resistance; —Part 5: Measurement of bridge circuit open resistance subsequent to actuation; —Part 6: Measurement of insulation resistance; —Part 7: Dielectric withstanding voltage test; —Part 8: Stab sensitivity test; —Part 9: Electric-fire sensitivity test; —Part 10: No-fire verification test for electric initiating explosive devices; —Part 11: 1A1W5min No-fire test; —Part 12: Measurement of radio-frequency impedance; —Part 13: Radio-frequency sensitivity test; —Part 14: Electrostatic discharge test; —Part 15: Stray current test; —Part 16: Steel dent test; —Part 17: Aluminum dent test; —Part 18: Lead disc test; —Part 19: Measurement of axial shockwave pattern generated by electric detonator detonating; —Part 20: Lucite bulkhead test; —Part 21: Measurement for function time of detonator; —Part 22: Measurement of function alsynchronization Probe method; —Part 23: Measurement of function alsynchronization Electron-optical method; —Part 24: Measurement of firing pressure-time curve; —Part 25: Measurement of flame length and flame duration of primer; —Part 26: Determination of bridge wire meltdown time; —Part 27: Temperature shock test; —Part 28: High temperature exposure test; —Part 29: Cook-off test; —Part 30: Temperature and humidity test; —Part 31: Immersion test; —Part 32: High frequency vibration test; —Part 33: Jolt test; —Part 34: Vibration test; —Part 35: 12 meter drop test; —Part 36: 2 meter drop test; —Part 37: Hammering test; —Part 38: Shock test. This is Part 32 of GJB 5309. This part was proposed by China North Industries Group Corporation Limited. This part is under the jurisdiction of China Ordnance Industrial Standardization Research Institute. Test methods of initiating explosive devices—Part 32:High frequency vibration test 1 Scope This part specifies the instruments, equipment and devices, test conditions, test procedures, result evaluation and precautions for high frequency vibration test of initiating explosive device. This part is applicable to high frequency vibration test of initiating explosive device. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part. For dated references, subsequent amendments (excluding corrections), or revisions, of any of these publications do not apply to this part. However, parties to agreements based on this part are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest editions apply to this part. GJB 5309.1 Test methods of initiating explosive devices—Part 1: General principles 3 Purpose Simulate the high-frequency vibration environment of initiating explosive device during transportation and use, and evaluate the safety and reliability of initiating explosive device after vibration. 4 Principle The sample is installed on the vibration test stand surface directly or firmly with a fixture, and an acceleration sensor is installed on the vibration test stand surface (or fixture). During the test, the vibration signal received by the acceleration sensor is converted and amplified into voltage signal by charge amplifier, and then transmitted to the vibration controller. The vibration controller compares, analyzes and equalizes the input value of the vibration test condition before the test with the received voltage signal to generate electrical signal. After that, the electrical signal is amplified by the power amplifier to drive the vibration test stand to vibrate according to specified vibration conditions. See Figure 1 for typical vibration testing system composition and test schematic diagram. 1-Vibration test stand; 2-Sample; 3-Sensor; 4-Charge amplifier; 5-Vibration controller; 6-Power amplifier; 7-Draught fan Figure 1 5 General requirements Application of this part shall comply with the relevant regulations of GJB 5309.1. 6 Instruments, equipment and devices 6.1 Vibration test stand The basic motion of the vibration test stand shall be a sinusoidal function of time, and each fixed point of the sample shall basically move in phase and along a parallel straight line; The magnetic leakage at 16cm above the vibration test stand surface shall be less than 10 gauss. 6.2 Vibration test system Within the entire test frequency range, the tolerance of vibration values at the control points shall meet the following requirements: ——Scanning time: ±3%; ——Vibration frequency: ±45% below 25Hz; ±2% at other frequencies; ——Vibration amplitude: ±10%. 6.3 Vibration fixture 6.3.1 Vibration fixture shall be able to ensure that the sample vibrates in the specified axial direction. 6.3.2 The vibration fixture shall be able to simulate the actual installation situation. If not, it shall have enough rigidity to ensure that the motion of vibration test stand is correctly transmitted to the sample. 6.3.3 The vibration fixture shall be designed to be symmetrical in mass distribution after loading the sample, so as to minimize the unbalanced load. 6.3.4 The natural frequency of the vibration fixture shall be at least three times the highest frequency of the test.
