Project Number 1

Test Objective:

Identify a replacement for TCE.

Product Use:

medical devices
Trial Number Date Run Purpose Success Rating
0 07/31/2019 To evaluate cleaners on their effectiveness at the removal of J2 oil using unheated immersion on titanium substrates. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
1 08/14/2019 To evaluate the effectiveness of solvent and aqueous based cleaners at the removal of J2 on titanium substrates. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
2 08/14/2019 To evaluate the effectiveness of solvent and aqueous based cleaners at the removal of J2 on titanium substrates. Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
3 12/31/1969 Five sets of 26-28 titanium parts were provided pre-contaminated with J2. Cleaners were heated to vendor recommended temperatures before immersing the parts into an ultrasonic tank for 15 minutes. Visual observations were recorded overall with notes and a set of three parts per cleaner were evaluated by three lab technicians, labelled A-C in Table 1, for cleaner and contaminant residue according using the rating key below. Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.
4 10/21/2019 To evaluate the dry time of two solvent products used to remove J2 oil from titanium parts. Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.
