دانلود کتاب Standard Test Method for Evaluating the Effectiveness of Cleaning Agents and Processes

۵.۱ The purpose of these test methods is to define a procedure for evaluating the capability and effectiveness of cleaning agents to remove residues of a compound/product from surrogate surfaces (that is, coupons or beakers) of Materials of Construction. This test method also provides a procedure for determining the compatibility of cleaning agents with the Material of Construction prior to starting tests. Based on the outcome of the testing, suitable cleaning agents may be selected for further cleaning process development (see Guide D۶۳۶۱/D۶۳۶۱M).

۵.۲ The potential critical cleaning parameters related to the cleaning agent(s) under study may also be examined using these tests. Potentially critical cleaning parameters include cleaning agent concentration, temperature, time, pH, foaming, type and strength of ultrasonic energy or agitation (if used), and others. These parameters may be varied (for example, using Design of Experiments) to determine their potential optimal settings for actual use.
