[27] You will discover standards often known as 'release technical specs' that samples tested need to satisfy statistically, both as person values and as ordinary of The entire.[28][29] Just one these criteria is the parameter "Q", which is a percentage price denoting the quantity of dissolved Energetic component throughout the monograph of the sample Option. If your Original sample Evaluation, known as S1 or stage 1 testing fails to fulfill the acceptable price for Q, then supplemental testing referred get more info to as phase 2 and three testing is necessary. S3 testing is executed provided that S2 testing nonetheless fails the Q parameter.
