Scope: This standard specifies the terminology and definitions, basic requirements, technical requirements, testing methods, inspection rules, marking, packaging, storage, preservation, and quality commitments for the spray-coding (hereinafter referred to as "wiring harness weaving") of engineering machinery wiring harnesses. This standard applies to the spray-coding of engineering machinery wiring harnesses; Main technical content: The engineering machinery industry is an important component of China's equipment industry. Its product categories include excavators, earthmoving and transport machinery, engineering lifting machinery, and more than eighteen other categories. It can be said that as long as there is engineering construction, engineering machinery is indispensable. Since the emergence of engineering machinery, with technological progress and continuous changes in business models, the industry has moved from the start-up period and formation period to the development period. Especially in recent years, the global engineering machinery industry has been in a state of steady growth, and the industry's pattern will not change fundamentally in the short term. The industry scale of the engineering machinery industry increased from 457.0 billion yuan at the end of the "Twelfth Five-Year Plan" (2015) to more than 700.0 billion yuan in 2020, with an average annual growth of about 8.96%. During the "Thirteenth Five-Year Plan" period, the engineering machinery industry deeply implemented the innovation-driven development strategy, continuously made new breakthroughs in the research and development and application promotion of core technologies for high-end and intelligent products, fully meeting the needs of major national economic construction projects, and emerging a large number of scientific research achievements, which has become an important driving force for the sustained growth of the industry. The "Going Global" of engineering machinery, on the one hand, e
