Properties

Adherence and flexibility	Single or Double with underlying film: no cracks visible in the film insulation after 20% elongation. Examine with normal vision and without removing the glass fiber covering.Double without underlying film: not less than 75 V/mil (2950 V/mm) of minimum thickness of the glass fiber covering on one side.  NOTE—The minimum thickness of the glass fiber covering is 35% of the maxi- mum increase in dimensions calculated from: Square 0.203mm-0.330mm
Elongation	Not less than 32% for a thickness of 0.049 in. (1.25 mm) and greater, or 30% for a thickness less than 0.049 in. (1.25 mm)
Springback	Glass fiber covered bare: not greater than 5ºGlass fiber covered Heavy film-insulated: not greater than 5.5º
Dielectric breakdown	Not less than 90 V/mil (3543 V/mm) of the minimum thickness of the glass fiber covering on one side plus the minimum breakdown given in the film-insulated wire(Heavy 500-1500；Quad 900-2500), if applicable.  NOTE—The minimum thickness of the glass fiber covering is 35% of the maxi-mum increase in dimensions calculated from:Single: 1.628mm-8.252mmDouble: 1.956mm-8.788mm
