ISC posts test data

gtzavelas · 27th March 2008, 12:44

ISC Information

great to see that ISC just posted A LOT of test data
including testing at 50m and 100m for 5 canister types
some APECS 2.5 Compliance Testing
and much more (including GOLEM BOV, HH electronics)

its great to see more and more data published
expect long discussions to start now...
I will strart:
how is it possible for the CISLunar radial canister to perform worse than the standard axial scrubber?
on the contrary the ExtendAir seems to be doing OK (better than the axial, worse than radial)

Its also important to note that the standars were a bit diferant than other testing. (75 RMV, 25bpm) so comparissions are not easy to make.
Question: doesnt EN specify RMV and BMM? Why each manufacturer is testing at diferant specs???

For GOLEM BOV owners (like me): I was surprised to see that it seems that the BOV fails the max WOB limit of 1,37

Bit defensive aren't they?

Dont think theres many (any?) make of BOV that does have a good WOB - this is why for me its only a step to OC bail (sanity breath)

Its good to see any test results.

Ive just read the one about the hammerhead so far.

I wonder whats behind this?

Is it that they intend to 3rd part test any aftermarket 'add ons' that are available for the Meg???

added: ok just read the golem bov test.

I wonder if Ron will be calling ISC 'traitors' for trying to put Golem/Juregeson Marine out of business

All joking aside good info being reported though, although Im sorely tempted to say they should maybe get their own house in order first

If I was a Rebreather mnf and people were commonly using aftermarket upgrades in my unit I too would want to test them to make sure they work as any death would be seen as a unit issue. Doubt Golem or JM will really appreciate the publicity though, although Im very sure they will take the issues highlighted on board and will if needed improve their products accordingly so it is in the long run a positive thing.

I like test results - whos next?

I imagine the resistance caused by the hydrophobic membrane...

Same here for me Mike. Sanity breath, then to OC.

This ranking is contrary to what they reported in their rebreather comparison brochure under different test conditions.

Look at pg 2.

I like the ide of the ISC Tall Gas Plenum Canister on

http://www.customrebreathers.com/News.html

This Gas Plenum Canister is designed specifically for the ISC 8.0 pound radial scrubber. Like the radial scrubbers, the tall can is an option. The taller plenum allows for a large water trap area below the radial canister. The taller can also allows for divers desiring better seating platform easing back strain while waiting to enter the water from a boat. The taller can may not allow for easier travel due to the longer length and the addtional size adds to weight. The taller can was requested by our New Jersey/New York divers wanting the 8.0 radial and features the taller can provides. This can is approximately 3 3/8 inches longer (21 1/8 inches) than the standard Meg canister.

Tall Gas Plenum Canister

Anyone out there in Rebreather World using one of these already and does it make a difference?

It's a great idea but will not be able to put this canister onto carry on, that's all.

interesting
the 75 RMV testing document (http://www.customrebreathers.com/75_RMV_can_testing.pdf) states that at 75 RMV both at 50m and 100m the Cis Lunar Radial has the highest WOB
so for lower RMV the Cis is better than the Axial and then for highier RMV the Cis is worse !
(not surprisingly WOB at 100m using 10/70 is lower than that of air at 50m)
