1. The issuing authority is different: the national standard is a standard adopted and publicly issued by national institutions. Industry standard refers to the technical requirements that need to be unified in an industry without recommended national standards. Enterprise standard is the standard of technical requirements, management requirements and work requirements that need to be coordinated and unified within the enterprise.
2, the authority is different: the national standard is generally mandatory and the most authoritative. If the enterprise standard is higher than the industry standard or the national standard, the enterprise standard for filing may also be implemented. Otherwise, national standards, industry standards and enterprise standards should be implemented in this order.
3. Formulate different standards: national standards, banking standards and enterprise standards are allowed to coexist, but the prerequisite is that when formulating standards, enterprise standards should be superior (higher) to bank standards and bank standards should be superior (higher) to national standards.
