Scope

Scope: This specification stipulates the technical requirements, quality assurance provisions, and delivery preparations for standard jet sources. This specification applies to standard jet sources with diameters of 56mm and 81mm (hereinafter referred to as 56mm standard jet sources and 81mm standard jet sources, respectively). Other specifications of standard jet sources may refer to this specification for implementation. Main technical content: 3 Requirements 3.1 Composition Standard jet sources are generally composed of an explosive column, a detonating column, a shaped charge cup, and a detonator fixing sleeve, etc. The structural schematic diagram is shown in Figure 1. The explosive column is made of JH-2 explosive (with a compacted density of 1.71 g/cm3), and the shaped charge cup is processed from GB/T 14594-2014 pure copper material. The standard jet sources are detonated by detonators provided by the purchaser. Figure 1 Structural schematic diagram of standard jet sources 3.2 Performance 3.2.1 Average penetration depth Unless otherwise specified, the average penetration depth of the standard jet sources against 45 GB/T 699 steel cylinders is required as shown in Table 1. Table 1 Requirements for average penetration depth Serial number Specification Blast height (mm) Average penetration depth (mm) 156mm standard jet sources 84 ± 5 205 ± 5 81mm standard jet sources 120 ± 10 305 ± 5 3.2.2 Relative deviation in penetration depth The relative deviation in penetration depth of the standard jet sources against 45 GB/T 699 steel cylinders shall not exceed 5%. 3.3 Transportation and vibration When subjected to transportation vibration tests in a packed state, there shall be no damage such as parts breaking, falling off, or loosening, and the standard jet sources shall function normally after the vibration. 3.4 Maintenance and safety 3.4.1 1.5m drop test When dropped from a height of 1.5m onto
