Trial Number 1

Client Number 142

Project Number 1

Trial Purpose:

To evaluate the effective cleaner at higher temperature and longer cleaning times.

Date Run:

09/07/2000

Experiment Procedure:

One chemistry, listed in Table 1, was selected based on the previous test 00-8142-01-2. The aqueous product was diluted to 5% in a VWR Scientific Products Aquasonic 150 HT ultrasonic tank using tap water at 115 F. One dirty part was cleaned in the solutions for 15 minutes, followed by a 30 second tap water spray at 120 F. The clean parts were then dried using a Master Appliance Corp, Hot-air gun model HG-301A at 500 F for one minute. Parts were then visually compared to the supplied cleaned parts and the other cleaners. The solution was then heated to 140 F and parts were cleaned for 5, 10 and 15 minutes. Each part was rinsed, dried and analyzed as mentioned previously.

SUBSTRATE MATERIAL: Steel
CONTAMINANTS: Oil, dirt, smut

Trial Results:

The part cleaned at 115 F was comparable in cleanliness to the part cleaned at 140 F at 5 minutes. The part cleaned for 15 minutes at 140 F was looked the cleanest of all the parts followed by the 10 minute cleaning. Table 2 lists the ranking of the parts and any observations made.

Table 2. Observations

Temp F Time (min) Observations
115 15 good
140 5 good
140 10 good/excellent
140 15 excellent

Excellent > Good > Okay > Fair > Poor

Success Rating:

A follow up test, usually based on company input.
