# 3300.7 General.

Testing of equipment according to the ATP is basically done in two phases:

(a) Measurement of the insulating capacity, that is, the K-coefficient, of the insulated body.

(b) Determination of the efficiency of the thermal appliance as installed in the insulated body. In the case of mechanically refrigerated equipment, the mechanical refrigerating appliance may be tested separate from the body.
