[0002] Product explosion testing is crucial in a wide range of fields, including power grids, fire protection, railways, power plants, petroleum, petrochemicals, large enterprises, and the military. When testing a product for explosion-proof testing, a potential failure can cause a propagation explosion, leading to excessive pressure inside the test chamber. Disposable pressure relief plates are typically used to provide this pressure relief. However, these plates require frequent replacement, resulting in high testing and labor costs and low efficiency.
