Standardization is a key indicator of an industry's maturity, and the field of folding machines has developed a multi-layered standard system. Basic safety standards, such as ISO 12100 (Safety of machinery — Basic concepts and general principles for design), apply to all folding machines, ensuring fundamental safety requirements. In terms of performance standards, two-fold machines primarily reference general industry standards, focusing on production efficiency, precision ranges, reliability indicators, and more. Although these standards are relatively lenient, leading manufacturers typically establish enterprise standards that exceed industry norms.

The standard system for three-fold machines is more comprehensive. In addition to safety standards, there are specialized performance testing standards, such as methods for testing folding accuracy, measuring changeover time, and evaluating energy consumption. Recommended standards established by industry organizations provide benchmarks for equipment comparison. In terms of quality certification, three-fold machines typically require market access certifications such as CE (European Union) and UL (North America), with some industries also requiring special certifications like EHEDG for food machinery.

As high-end equipment, four-fold machines are subject to the most stringent standard requirements. Precision standards reach the micrometer level, and stability standards require performance maintenance during long-term operation. International organizations such as ISO and national standard bodies have developed standards specifically for high-precision packaging equipment. Beyond mandatory safety certifications, four-fold machines also pursue voluntary quality certifications, such as TÜV certification, as proof of quality assurance. In specific industries like pharmaceutical packaging, compliance with specialized standards such as GMP and FDA is also required.

The standard system not only regulates equipment manufacturing but also guides users in procurement and usage. Procurement technical specifications are typically formulated based on relevant standards to ensure equipment meets basic requirements. Acceptance testing procedures refer to standardized methods, reducing disputes between suppliers and buyers. Operation and maintenance manuals are written in standardized formats to enhance usability.

The challenge of standardization lies in balancing uniformity with innovation space. Excessively strict standards may stifle technological innovation, while overly lenient standards fail to guarantee basic quality. The development trend is to maintain strict uniformity for core safety standards while offering multiple levels of performance standards for selection, encouraging enterprises to innovate and compete while meeting basic requirements.

The improvement of certification systems provides third-party verification of equipment quality. From safety assessments during the design phase to quality control during manufacturing and periodic inspections during usage, a complete certification system ensures the safety and reliability of equipment throughout its lifecycle. With the development of globalization, the convergence of international standards and mutual recognition of certifications have become important trends, reducing technical barriers to trade and promoting the exchange of equipment and technology.
