4、2 Clause 1 of the Industrial Standardization Law applicable to the case of revision by the provision of Article 14. Consequently JIS G 3469 : 1992 is replaced with this Standard. Attention is drawn to the possibility that some parts of this Standard may conflict with a patent right, application for
5、a patent after opening to the public, utility model right or application for registration of utility model after opening to the public which have technical properties. The relevant Minister and the Japanese Industrial Standards Committee are not responsible for identifying the patent right, applicat
