10、,- JAPANESE INDUSTRIAL STANDARD JIS C 6489 : 1999 Base materials for printed circuits- Epoxide non-woven/woven glass reinforced copper-clad laminated sheet of defined flammability (vertical burning test) Introduction This Japanese Industrial Standard has been prepared based on the first edition of I
11、EC 60249-2-10 Base materials for printed circuits-Part 2 : Specifi- cations-Specification No. 1 O : Epoxide non-woven I woven glass reinforced copper-clad laminated sheet of defined flammability (vertical burning test) published in 1987 without modifying the technical contents. However, a partial mo
12、dification has been given according to the actual condition in Japan and, in addition, the amendment to the said International Standard has been integrated into the text. Portions underlined with dots are the matters not stated in the original Interna- tional Standard. The IEC Standard number is bas
13、ed on the new numbering system of IEC Stan- dards put in force on January 1st 1997, and the Standard published before the said date is numbered by adding 60000 to the former number. This is only the change in the numbering system and the contents remain unchanged. 1 Scope This specification gives re
14、quirements for properties of epoxide non-woven/ woven glass reinforced copper-clad laminated sheet of defined flammability (vertical fire resistance), in thicknesses of 0.7 mm up to 3.2 mm (hereafter referred to as “copper- clad laminated sheet”). Remarks 1 To designate this material, the reference:
15、 60249-2-1 O-FVO-IEC-EP- GF+GC-Cu may be used; if there is no risk of confusion, the type designation may be abbreviated to read IEC-60249-2-10-FVO. 2 The International Standard corresponding to this Standard is given below. IEC 60249-2-10 : 1987 Base materials for printed circuits-Part 2 : Specific
16、ations-Specification No. 1 O : Epoxide non-wouen I woven glass reinforced copper-clad laminated sheet of defined flamma- bility (vertical burning test) 2 Normative references The following standards contain provisions which, through reference in this Standard, constitute provisions of this Standard.
