PT 86a: Waters under bacteriological control. In this program, laboratories perform Total viable count at 22°C & 36°C and Pseudomonas aeruginosa, on bacteriologically controlled waters.

PT 86b: Microbiology of dialysis waters (hemodiafiltration). This program proposes ultrapure water (dialysate) and laboratories will be able to analyse for Total viable count at 22°C for 7 days on medium similar to R2A or TGEA media identification of indicator microorganisms.

PT 86c: Microbiology of endoscope rinse waters. This program offers Total viable count at 22°C and identification of indicator microorganisms on an endoscope rinse water.
