A few days ago, the "Notice of the First Batch of National Standards Revision Plans for 2013" was announced. In 2013, a total of 96 project plans were arranged. Among them, 90 items were formulated, 6 items were revised, 80 items of product standards, 14 items of engineering construction standards, and 2 items of safety production standards. Including "Non-destructive testing equipment sampling factory inspection requirements", "Non-destructive testing equipment industrial X-ray digital imaging device performance testing rules", "NDT equipment industrial electronic endoscopy detector", "NDT equipment industrial fiber optic endoscopy detector "Technical Requirements for Non-destructive Testing Instruments, Infrared Thermal Imaging Systems and Equipment," "Nondestructive Testing Instruments," "Non-Destructive Testing Instruments, Automotive Hub X-Ray Real-Time Imaging Detectors," "Non-Destructive Testing Instruments, Eddy-Current Magnetic Flux Leak Detectors," †and several other criteria were drafted.
The revision of the industry standards is based on the current situation in the development of the industrial sector and the needs of industrial development, formulating standards for new technologies, new products, and new materials that have a major impact on promoting the adjustment and optimization of industrial structure; improving the energy conservation and emission reduction standard system and setting key industries Energy-saving and consumption-reducing products and resources comprehensive utilization standards; revision of low-level standards and upgrading of standard technology levels to meet the needs of industrial development.
"Non-destructive testing is not a new technology. In the early 1930s, people began to use magnetic powder to detect flaws in aviation steel parts." Xi'an Jinbo Testing Instrument Co., Ltd. is a non-destructive testing company with international advanced technology in our city. The general manager of the company, Dr. Xiaojun Liu, said that with the continuous development of industry and science and technology, the use of hammer, light, magnetic and electrical characteristics of the instrument after the use of hammerhead, ear hearing detection "soil method" gradually out of date The "modernized non-destructive testing technology" of inspection has become one of the most important and most widely used technologies in modern quality management systems.
"In the non-destructive testing process, regardless of the use of traditional ultrasonic non-destructive testing technology, or the use of visual ultrasound non-destructive testing methods that are compared to the "B-ultrasound" technology, human factors are crucial, even as high as 70%." Dr. Liu Xiaojun thinks No matter whether it is aerospace, aviation, or nuclear power, petroleum, petrochemical equipment, we must rely on non-destructive testing personnel to carry out professional inspections. Only under the premise of ensuring reliable quality can we achieve smooth construction of engineering construction and large-scale equipment. Otherwise, any equipment inside the micro Defects can cause unimaginable consequences.
