A detailed comparison is made of the recommended procedures and equipment for measuring the speeds of sputter-ion pumps as proffered by: i) the ISO in DRAFT INTERNATIONAL STANDARD ISO/DIS 3556-1,2 (1992); ii) the DEUTSCHE NORM Acceptance specification for sputter-ion pumps DIN 28 429 (1985); and, iii) the AVS Recommended procedure for measuring pumping speed, no number (1987). The purpose of this work is to: highlight the concurrences and disparities between the "standards", ii) suggest reasonable criterion relating to procedures and equipment; and, iii) propose a more global template for such measurements.
