ANNEX A
    
   1.0 DEFINITIONS
    
   Crazing: Cracks in the glaze of an insulator
 
 Dunt: A fracture extending through the  body, or the body and the glaze, caused by strains set up in the process of manufacture.
  
 Speck: A discoloured portion having a dimension larger than 0.062 inches
 (1.575 mm)
 
 MANUFACTURING DETAILS                     MINIMUM  REQUIREMENTS

a) BISCUIT FIRING TEMPERATURES:            1050  °C

b) KILN FIRING TEMPERATURES:                 1250  °C

c) SAMPLE SIZE TO BE TESTED                   10 %

 
BODY PREPARATION
Manufacturers must ensure that the Entropy of mixing is achieved in order to ensure all the constant materials making the body are properly mixed
 
MATERIAL
The porcelain shall be sound, thoroughly vitrified, smoothly glazed and shall be free from dunts, projections and exposed body. There shall be not more than five specks on the insulator. The glazing shall not be relied upon for the insulating properties of the insulator.
GLAZING
The glaze, which shall show no signs of crazing, shall be leadless and shall cover the insulator entirely except for kiln support marks, screw threads.
 
MECHANICAL DESIGN
The design shall be such that stresses due to expansion and contraction in any part of the insulator do not lead to deterioration.
