TAM PANEL CLEANING PROCEDURE Probably the most important step of Penetrant Inspection is precleaning the part. This rule certainly applies to the test panels you use. If your parts aren’t clean, you won’t find the cracks, and if your test panels aren’t clean, you will not find the indications. Many times we get Tam panels back from a customer who says they are not finding the number of indications they should. The first thing we do, before even questioning their processing steps, is clean the panel and test it. The majority of the time, after proper cleaning, all indications are visible. Below is the cleaning procedure we have found that works the best for cleaning Tam panels. A. Prepare 20% concentration (3 units on Refractometer) solution of Magna-Vu and heat to 140°F. in the ultrasonic unit B. Place panel face down (chrome plated side down) in basket. Clean panels for at least 30 min. with the Magna-Vu solution at 140°F. C. Rinse panels for 90 sec. with a water spray at a pressure of 25psi. (5psi. tolerance), approximately 18” from the panels, and the water temperature at 75°F (10°F tolerance). (For heavy duty cleaning go to step E below) D. Dry panels in drying oven for 20 min. at 140°F (10°F tolerance). For heavy duty cleaning use a lime removal product such as CLR . E. Immerse panels for 5 min. in a solution of 100% CLR. F. Rinse panels for 90 sec. with a water spray at a pressure of 25psi. (5psi. tolerance), approximately 18” from the panels, and the water temperature at 75°F (10°F tolerance). G. Dry panel in drying oven for 2 min. at 140F. March 2004

TAM PANEL CLEANING PROCEDURE

Probably the most important step of Penetrant Inspection is precleaning the part. This rule certainly applies to the test panels you use. If your parts aren’t clean, you won’t find the cracks, and if your test panels aren’t clean, you will not find the indications. Many times we get Tam panels back from a customer who says they are not finding the number of indications they should. The first thing we do, before even questioning their processing steps, is clean the panel and test it. The majority of the time, after proper cleaning, all indications are visible. Below is the cleaning procedure we have found that works the best for cleaning Tam panels.

A. Prepare 20% concentration (3 units on Refractometer) solution of Magna-Vu and heat to 140°F. in the ultrasonic unit

B. Place panel face down (chrome plated side down) in basket. Clean panels for at least 30 min. with the Magna-Vu solution at 140°F.

C. Rinse panels for 90 sec. with a water spray at a pressure of 25psi. (5psi. tolerance), approximately 18” from the panels, and the water temperature at 75°F (10°F tolerance).

(For heavy duty cleaning go to step E below)

D. Dry panels in drying oven for 20 min. at 140°F (10°F tolerance).

For heavy duty cleaning use a lime removal product such as CLR.

E. Immerse panels for 5 min. in a solution of 100% CLR.

F. Rinse panels for 90 sec. with a water spray at a pressure of 25psi. (5psi. tolerance), approximately 18” from the panels, and the water temperature at 75°F (10°F tolerance).
