Compliance overview
Scope and applicability
This standard applies to the manufacturing and acceptance of launch barrels (mortars) specifically designed for firing display shells in fireworks. It covers barrels made from various materials, including paper, fiberglass, and metal (such as steel or aluminum). It is important to note that paper barrels are strictly prohibited for shells Size 5 and above. This standard is essential for manufacturers and quality inspectors involved in the production of professional fireworks display equipment.
Technical requirements
The standard specifies comprehensive technical requirements for launch barrels, focusing on appearance, dimensional specifications, and pressure resistance. Visually, the barrel body must be free from deformation, and the inner cavity must be smooth and perpendicular to the base. Fiberglass and metal barrels are required to have reinforcement rings at both the muzzle and base. Dimensionally, the inner diameter must align with the corresponding shell sizes defined in GB 19594-2004. The standard dictates strict parameters for wall thickness, inner barrel height, and base thickness across different size categories (from Size 3 to Size 16). Manufacturers must ensure that all dimensional tolerances strictly adhere to the defined limits to prevent launching failures. Regarding performance, the barrel structure must be robust enough to withstand specific internal pressure limits without experiencing structural failures. The standard explicitly defines criteria for failure modes such as base blowout (冲底), barrel rupture (炸筒), perforation, leakage, and deformation.
Testing methods
The standard outlines several key testing methodologies to validate compliance. Visual inspection is used to assess surface quality and markings. Dimensional verifications are conducted using calipers and thickness gauges, measuring the inner diameter, wall thickness, and overall height at multiple points. For performance evaluation, a drop test is specified to verify the structural integrity of the base and body. Furthermore, a critical hydrostatic pressure test is conducted using a specialized pressure testing machine. This test subjects the sealed barrel to specific internal pressure for 15 minutes to ensure no cracking, leakage, or rupture occurs.
FAQs
What products are regulated under GB 20208-2006?
The standard regulates launch barrels (mortars) used for firing display shells in fireworks. It covers barrels made of paper, fiberglass, and metal materials.
Are there material restrictions for specific shell sizes?
Yes, the standard explicitly prohibits the use of paper barrels for Size 5 and larger shells due to safety and pressure resistance concerns. Only fiberglass or metal barrels are permitted for these sizes.
How does GB 20208-2006 relate to other fireworks standards?
The standard references GB 19594-2004 for the inner diameter specifications of the shells. The barrels must strictly match these dimensional requirements to ensure safe and proper launching.
