  3.2 Test Values for Silicone Fluid as Received (Prior to
      Filling Equipments)
  3.3 Filling with Silicone Fluid
4 Testing and Evaluation of Fluid in Equipment
  4.1 Periodic Fluid Inspection and Testing
  4.2 Test Limits for Silicone Fluid in New Equipment
  4.3 Treatment of Contaminated Silicone Fluid
5 Storage, Handling, and Safety Instructions
  5.1 Storage
  5.2 Handling
  5.3 Safety Instructions

Specifies standard tests and evaluation procedures for silicone transformer fluid. Criteria for maintenance and methods of reconditioning of silicone fluid are described. It is not the intent of this guide to cover the subject of retrofilling transformers with silicone fluids.
