39、 COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULappliance becomes unstable and begins to overturn. By repeating this process with the deep fryer,cooker/fryer, large item deep fryer, large item cooker/fryer, or oil fondue appliance rotated in var
40、iouspositions against the low stop, the position that is least stable is to be determined. This minimum angle tocause tipover is to be recorded as Alpha 1 (1). See A of Figure 38.1.38.4 The deep fryer, cooker/fryer, large item deep fryer, large item cooker/fryer, or oil fondue appliance isto be rota
41、ted 180 degrees on the inclined plane and the angle increased until the deep fryer, cooker/fryer,large item deep fryer, large item cooker/fryer, or oil fondue appliance becomes unstable and begins totip-over. This angle is to be recorded as Beta 1 (1). See B of Figure 38.1.38.5 The deep fryer, cooke
