GB/T 7994.3 - 2022 is the third part of the standard for the test method of Glass-lined equipment, focusing on the mechanical impact resistance test. The standard specifies the parameters of test equipment, such as special shooting devices. Clarify the sample preparation, including the selection requirements for the specimen of Glass-lined equipment. Explain the test operation process in detail, from the control of the shooting force to the selection of the Impact point and the determination of the result. Through this test, the ability of Glass-lined equipment to withstand mechanical Impact is accurately evaluated, which provides a key basis for its mass detection and ensures the safe and stable operation of the equipment in the industrial environment that may be subject to Impact.
