International annealed copper standard, a value for conductivity agreed in 1913 with copper being given the value of 100%, equivalent to 58MS/m or a mass resistivity of 0.15176 Ωg/m2. Advances in refining mean that high conductivity copper is now frequently of 103% conductivity.

(Integrated Administrative Control System) The method used to control the amount of crops grown on farms by the EU. Finacial penalties apply to those who do not follow the rules to the letter.It has been superceded by an even more complex and bureaucratic system (2005) called the SFP (Single Farm Payment).

International Annealed Copper Standard - a measure of electrical conductivity agreed in 1913 with “pure” Copper set as 100%. Advances in copper refining mean that now the pure Copper can attain 103% IACS. The minimum requirement for High Conductivity Copper now is 101% IACS.
