  ISO9001 certification is one of the core standards of the quality management system, which is included in the ISO9000 group standard. ISO9000 family standards is the international organization for Standardization (ISO) in 1994 proposed the concept of "by the ISO/Tc176 (International Organization for standardization of quality management and quality assurance technical committee) to develop international standards. ISO9001 certification is used to confirm that the organization has the ability to provide products that meet customer requirements and applicable regulatory requirements. The purpose is to enhance customer satisfaction. With the commodity economy and growing internationalization, in order to improve product reputation, reduce duplication of inspection, to weaken and eliminate technical barriers to trade, safeguard the producers, distribution, user and consumer rights and interests of all parties, the certification from the economic interests of both sides to control production and marketing, notary, science. All enterprises through the ISO9001 certification, in the management system integration has reached the international standard, indicating that the enterprise can continuously and stably provide customers with expectations and satisfaction of qualified products. Standing in the consumer's point of view, the company to customers as the center, to meet customer demand, to achieve customer satisfaction, not to induce consumers.

  Sairui international certification was founded in the year 1918, with nearly 100 years of history, branches all over the world. CSC international certification is UKAS accredited testing and certification bodies, is one of the few people who also have product certification, measurement, inspection and test, quality management system certification, environmental management system certification, occupational health and safety management system and certification of personnel authority, is one of the earliest UKAS accredited certification bodies, UKAS accreditation No. 11, is the world's largest explosion proof product certification bodies, is the British government designated global only MCERTS certification and personnel ability certification institutions. The official certification Commission has Sairui international certification bodies approved for Chinese recognition. Approval number: CNCA-RF-2003-29.

  "CE" logo is a safety certification mark, is regarded as the manufacturer to open and enter the European market passport." CE "represents the European unity (EUROPEENNE CONFORMITE).

  In the EU market "CE mark is mandatory attestation mark, whether the EU enterprises produced products, or products of other countries in the production, in order to the free circulation in the EU market, we must with" CE "label, to indicate that the products comply with the essential requirements of the technical standard and coordination of directives. This is a mandatory requirement of EU law for the product.

  Explosion proof certification is mandatory national certification. National Instruments and meters explosion-proof safety inspection station (nepsi) is authorized by the state, professional engaged in explosion-proof basic technology research and explosion proof test, product certification and project explosion-proof safety inspection, evaluation of technical institutions nepsi is the International Electrotechnical Commission IECEx organization recognized international explosion proof laboratory; is authorized by the State Administration of production safety supervision and management of national safety production Shanghai explosion-proof electrical inspection center (national safety test for Grade A qualification), is approved by the General Administration of quality supervision, inspection and Quarantine (AQSIQ), the establishment of a national industrial products production license office explosion-proof electrical equipment review Department of explosion-proof instrument workstation.

  In accordance with relevant laws and regulations of China, usually explosion-proof products and products for explosion proof occasion must advance by China's official explosion safety supervision and inspection station inspection and issue the explosionproof qualification certificate "before production and sales.

  The EC Council adopted the resolution on the new approach to technical coordination and standardization in May 7, 1985 (by the 98/34/EC directive instead). With technical regulations and standards as a means, only when related to product safety, industrial safety, human health, consumer protection and the protection of the environment in terms of technical requirements, to formulate the relevant technical regulations (i.e. instruction), and the cross by the relevant technical standards to regulate the specific technical details. Since 1985, implementation of the "new approach" since the promulgation of the new technical regulations instructions 32 (including for use in potentially explosive atmospheres equipment equipment for of atmospheres -ATEX instruction, where these directives relating to the products and shall be affixed with a CE mark, the party can be in the European market circulation, in addition to 4 does not specify the CE marking instructions. These are collectively referred to as the "New Approach Directives".

  In March 23, 1994, the European Commission adopted the "equipment and protection system for potential explosive environment" (94/9/EC) directive. It includes mechanical equipment and electrical equipment, the potential explosion hazard environment is extended to dust and combustible gas in the air, flammable vapor and mist. The directive is commonly referred to as the ATEX100A's "new method" directive, i.e., the current ATEX explosion-proof instruction. It provides technical requirements for equipment intended to be used in potentially explosive environments - the basic health and safety requirements and the conformity assessment procedures that must be applied before the equipment is put into the European market.

  ATEX directive enforced from July 1, 2003. The products covered by the ATEX directive are divided into different groups. According to the time and frequency division of explosive gas. Regions of different grades have different levels of safety requirements for the product.

  The utility model patent, also known as the object of the patent right, is the object of the patent law, and the utility model is a practical new type of patent right. China's "patent law" clearly the utility model as one of the objects of patent protection, the provisions of the utility model patents refer to: product shape, structure, or the combination of the proposed new technical solutions for practical. The technical level of the technical level is lower than the invention patent.
