GB 16914—2003
This standard adopts the European Community's /306/E directive (English version) containing the French and English versions of the standards of various countries on gas appliances. According to the European Community's SC/3/FFC directive, the draft is revised. Appendix A lists the comparison table between the terminal numbers of this standard and the European Community's 90/396/EEC directive article numbers. Taking into account my country's national conditions, this standard has made some subsequent changes when adopting the European Community's 90/396/EEC directive. The relevant technical differences are indented in the text and marked with a vertical single line in the blanks where the clauses involved are covered. The appendix lists the technical differences between the two standards and the 90/96/EEC directive.
To make the standard more suitable for the European Community SLR/EFC Directive, the following changes have been made to this standard: "This Directive" is changed to "This Standard"; the preface of this standard is the same as that of the European Community SLR/EFC Directive. This standard replaces GB16914-1937 General Test Method for Safety Technology of Gas Combustion Equipment. The main changes of this standard compared with G16914-1997 are as follows: 1) The detailed and specific safety technical provisions are changed to general safety technical provisions, and the requirements of this standard are all informative annexes. The main body of this standard is the Ministry of Construction of the People's Republic of China, the Ministry of Construction of the People's Republic of China, the North China Design Institute of the Ministry of Construction of the People's Republic of China, and the units of this standard are: North China Design Institute of the People's Republic of China, Ningbo Fangtai Mother Soldiers Co., Ltd.

All countries have the responsibility to protect the safety and security of people, animals and plants, and prevent accidents and hazards that may occur in gas combustion appliances (simple gas appliances) during use and aging. Countries around the world have determined safety levels and mandatory clauses through technical regulations, standards and consultation and assessment procedures. These levels and clauses should not become a risk between countries. It is up to the parties to help appliance sellers legislate continuously, and under the premise of ensuring safety and environmental protection, they should try their best to reduce barriers to sales and ensure Self-disclosure.
In order to strengthen the management of fuel, develop the socialist market economy and benefit the international trade, according to the provisions of relevant domestic and foreign standards and technical regulations, a practical standard is formulated.
The standard is based on the scientific research of fuel quality, and is based on the quality of fuel. This standard cannot be closely matched with the relevant standards to provide a practical basis for market access. Features of this standard:
This standard is based on the basic requirements it is intended to meet. It has no binding force on the way and method of achieving the basic six requirements. Any product that meets the fuel standard can be presumed to meet the requirements of this standard, so it can be filtered on the market. The conformity assessment procedure ensures the effective implementation of this standard. The form of acceptance assessment shall be carried out in accordance with relevant regulations of my country. c) The main business department of the country shall designate an institution to carry out conformity assessment in accordance with the relevant regulations and procedures to ensure that the product meets the requirements of the relevant standards before it is put on the market.
