In 1998, the ASBC, EBC, IoB (now IGB) and BCOJ began working together toward the creation and international adoption of a single set of HPLC standards for use in the quantitative determination of isomerized and reducedisomerized α-acids in hop products and in beers . The resultant International Calibration Standards (ICS) were produced, analyzed, and verified for the benefit of the brewing industry by the International Sub-committee for Isomerized Hop α-Acids Standards and first released in 2001, since which time the standards have been superseded by new preparations.
