1 Scope

This standard specifies the requirements for lighters to ensure reasonable security under the user during normal use or foreseeable misuse situations degree. This standard applies to all consumers commonly known cigarette lighters, cigar lighters and pipe lighters. This standard does not match or other ignition means for igniting other than cigarettes, cigars, pipe material. As a tool to produce lighter flame, flame and other sources as potentially harmful to the user. This standard does not exclude all Harm, but try to minimize the potential harm to the user to a minimum.

2 Terms and Definitions
