Environmental Testing Organizations (USA)

• The Institute of Environmental Sciences and Technology (IEST), founded in 1953 as a not-for-profit association, is a multidisciplinary, international society whose members are internationally recognized for their contributions to the environmental sciences in the areas of contamination control in electronics manufacturing and pharmaceutical processes; design, test, and evaluation of commercial and military equipment; and product reliability issues associated with commercial and military systems.
  
  The word "environmental" in thier name refers to IEST's ongoing interest in these areas: the effects on equipment and machinery of natural, indoor, and extreme environments, which may occur under various aerospace, naval, and climatic conditions; simulating environments to better trace and predict those effects; and controlling the environments in which products are manufactured, processed, or tested.
  
  IEST is the foremost organization addressing issues connected with contamination control. Thus, IEST will contribute a significant and unique expertise to the US TAG to TC 229 Nanotechnology. IEST is the Secretariat of ISO TC 209 Cleanrooms and associated controlled environments, and Administrator of the US TAG to ISO TC 209 which is responsible for establishing worldwide standards for cleanrooms.

  ANSI/IEST/ISO 14644-1:1999 Cleanrooms and associated controlled environments—Part 1: Classification of air cleanliness and ANSI/IEST/ISO 14644-2:2000 Cleanrooms and associated controlled environments—Part 2: Specifications for testing and monitoring to prove continued compliance with ISO 14644-1, established the airborne particulate cleanliness classes for particles sizes ranging from 0.1 µm to 5 µm. IEST, therefore, is in a unique position to apply its knowledge and experience in particle classification to related nanotechnology classifications.

• Electromagnetism (Wikipedia) -- "Electromagnetism is the physics of the electromagnetic field: a field, encompassing all of space, which exerts a force on those particles that possess a property known as electric charge, and is in turn affected by the presence and motion of such particles. The term electrodynamics is sometimes used to refer to the combination of electromagnetism with mechanics, and deals with the effects of the electromagnetic field on the dynamic behavior of electrically-charged particles."

• Faraday's Law -- "Any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be "induced" in the coil. No matter how the change is produced, the voltage will be generated. The change could be produced by changing the magnetic field strength, moving a magnet toward or away from the coil, moving the coil into or out of the magnetic field, rotating the coil relative to the magnet, etc." (Hyperphysics)
