JB/T 1544-1999 Rapid test procedure for thermal endurance of electrical insulating impregnating varnishes and varnished fabrics-thermogravameric point slope(Tps) method (English Version)
Rapid test procedure for thermal endurance of electrical insulating impregnating varnishes and varnished fabrics-thermogravameric point slope(Tps) method
1 Scope
This standard is applicable to the rapid test for thermal endurance of electrical insulating impregnating varnishes and varnished fabrics with soft film, which is expressed as the formula of temperature index (td) versus thermal endurance.
This standard can't supersede the conventional test procedure for thermal endurance.
