The secondary standard of Emf is the unsaturated Weston cell. Unsaturated Weston Cell Construction and Characteristics. The construction of an unsaturated cell is shown in fig. The unsaturated cell is similar to a saturated cell except that it does not have the cadmium sulphate crystals (CdSO4). It has the same electrodes but the solution is

The primary standard of luminous intensity in a full radiator (black body or Planckian radiator) at the temperature of solidification of platinum (2.042°k approximately) under a pressure of 101.325 kN/m². The “candela” is then defined as one sixtieth of luminous intensity per square metre of one full radiator. Secondary standards of luminous intensity are special
