ISO9001 is one of the core standards of quality management systems included in the ISO9000 family of standards. The ISO9000 family of standards is a concept put forward by the International Organization for Standardization (ISO) in 1994,

referring to the international standards formulated by ISO/TC176 (Technical Committee for Quality Management and Quality Assurance of the International Organization for Standardization).

ISO9001 is used to demonstrate an organization's ability to consistently provide products that meet customer requirements and applicable statutory and regulatory requirements, aiming to enhance customer satisfaction. With the continuous expansion and increasing internationalization of commodity economy,

to improve product reputation, reduce repeated inspections, weaken and eliminate technical barriers to trade, and safeguard the rights and interests of producers, distributors, users and consumers, such third-party certification bodies are not subject to the economic interests of producers and sellers.

Impartial and scientific, certification serves as a passport for all countries to evaluate and supervise the quality of products and enterprises; it acts as the basis for customers to audit suppliers' quality systems,

verifying enterprises' capability to meet the technical requirements of ordered products. Enterprises that have obtained certification have met international standards in the integration of various management systems, which indicates that they can continuously and stably

supply expected and satisfactory qualified products to customers. From consumers' perspective, certified enterprises take customers as the focus, satisfy customer demands, achieve customer satisfaction and refrain from misleading consumers.

In response to the needs of international trade development and problems emerging during standard implementation, especially the growing proportion of service industry in the global economy. Absorbing advanced international quality management

philosophies and adopting the PDCA cycle philosophy of quality, the standard is highly practical and instructive for both suppliers and buyers of products and services. Therefore, upon its release, the standard has been widely recognized worldwide.

So far, more than 70 countries around the world have directly adopted or equivalently transformed it into corresponding national standards, and over 50 countries have established quality system certification/registration bodies,

creating a global upsurge of standard implementation and certification. At present, hundreds of thousands of manufacturing enterprises, government agencies, service organizations and other types of organizations worldwide have adopted ISO9000 and obtained third-party

certification.

ISO9001:2015 was officially released in September 2015. This major revision incorporates changes formulated based on feedback from global users and experts.
