Simple load test. 2 vices bolted down. Get some rated cord/perlon up to half that of the unit is rated at, or you wish it to be. Attach unit to vice (creativity can count here), most official testing is done in tension, a shear test on a stiff stemed cam could result in deformity. connect test cord to the other open vice and to the unit to be tested. crank the vice shut. The vice threahd will have the tourque to obtain at least enough force to break your cord if not unit. This creates a reasonable user friendly nondestructive test for these units.
The supertopo website has some other versions on home made testing with pictures under threads on CCH Aliens.

Funnily enough i grew up in Castlereagh. But it isnt there, just up the road in glorious Londonderry. Always wondered what the hell that building was used for.....

Where did they break? (the device itself).

I thought the only things in Londonderry were Bikers, Bogans and dope crops! I lived in ultra selubrious Agnes Banks in a former life. What is the govt. building there? Maybe they could be coerced to carry out a few tests...

These people may help, too - rocks are often crushed to test for hardness/mechanical 'weathering', and the Dep't Mineral Resources might advise.

another testing option is to find a rope acces worker/rigger who has a load cell

The way I plan to test them doesn't involve load cells, vices or government departments.
Actually, WW&S , if we can both manage to coordinate two days off at the same time and get over to that big crack, you will probably get to see me test em.

There is no nylon locking mecanism on most fixed hangers, yet you trust those don't you?

Yep, look like nylocks to me too - but why is that an issue? It's rough but hey, these cams aren't the purdiest anyway, are they?
Looks like beefy cable, how much do they weigh wallwombat?

The cables are beefy. They don't seem to weigh much more than a equivalent tech friend .
They aren't nylock nuts. It's a double swage with heat shrink around it .

Hi
I was already looking at those myself, but like a few others wasn't too sure. Have you used them yet, and if so how are they? Would you be happy to fall on them or just use them for aid?
|
2-Dec-2007 1:00:22 PM

Yes they are fine. I haven't fallen on one yet but would be happy to. They are beefy.

Not too far off-route - but I have some 10 plus year old cams that I have never had identified but saw
some very similar,but couldn't be sure because of poor resolution, in a photo re testing of 'Ukranian' cams
. . . whew, finally , the connection and a rest.
Anyway, I have fallen on them, and the 7'ish mm cord that I tied on to them, well and good both free
climbing and aid climbing for 10 plus years, I am sure the se new ones will be fine.
To me they look like an exact BD copy and if you copy a cam you end up with a cam.

Yeah how can you give fair dinkum feedback on gear without a fall to base it on? :P (tongue in cheek symbol).
... & the waiting crowd took up the chant "jump womby jump", ... "jump womby jump"
