I am still running the efficiency capacity for you. That is not changing. Just the cold sim fluid Pressure vs flow is not going to be run.

It's not the test, but rather changing the fluid. I have another project that requires the same fluid that is currently in the test rig so I want to get it done for them ASAP in hopes for return business. I can ask a current customer if they will allow me to private message you data on another...

I'm sorry 53 Stude, I will not be doing the cold weather simulation. Finished the hot sim last night however, and I think you will like it. I am new to filming and had a little trouble getting the camera to auto focus on the pressure gauge display. I will have it to you as soon as I can...

I finished the 5 warm simulation Pressure Vs Flow Tests (ISO 4548-1) and filmed them. Will start editing the video when I get more time. One exhibited a strange behavior and was noticeably more restrictive than the others. Due to my current work load, unfortunately I will not be running the cold...

You switched your temps here, but yes exactly. It's easier to heat a fluid up then to cool it down to reach a target viscosity. I also don't like to get fluids to hot. Around 40C is where I don't like to go beyond if I can help it. Nice graphs and homework on this equivalency!

The cold sim fluid is... pardon my French some really nasty **** to work with.

Great to hear from you Z! I use 2 separate fluids. Hot simulation has a kinematic viscosity of 13.5 mm^2/s at 40 deg C, and cold simulation has a kinematic Viscosity of 500 mm^2/s at 38 deg C.

I pressure tested the filter base with my welded threads. Everything checks out. Please bear with me while I get the Pressure vs Flow test ready for you guys. I am debating on doing only a warm weather simulation, or changing the fluid out and doing a cold weather simulation as well. Please let...

I really appreciate it thank you! Perhaps we can get enough exposure to talk to Purolator and run some testing for them. I ordered a half dozen thread adapters and none fit the filter and the filter base, only one of each. If I didn't come up with a thread that fit to run the other tests, these...

Thanks Farnsworth! The isopropyl is commonly used for bubble point/integrity testing due to it being very easy to get a completely wetted media very quickly after it is submerged. Also the surface tension is not subject to variation as other fluids. It evaporates quickly to reduce time for...

Wow thanks Mainia!! I really appreciate it! It sure would be something if my small filter testing labs name got out there!

We will be testing a second set of new filters for the next tests. I do not have a housing for those elements to run further tests on.

I used to wear gloves years ago, I am impervious to all fluids now.

I just turned on the comments for the video so please let me know what you all think (2) Bubble Point Testing Oil Filters - YouTube

No more mystery thread. Just cut and welded 2 thread adaptors into one that works for this filter and filter base. Nobody has the correct adaptor I got tired of looking.
