ASTM 2170-11

RE: ASTM 2170-11
This is awesome. Not only am I improving my professional knowledge on slab testing, I am getting a fix of hardcore military weapons goss from ex-army personnel! All I need now is to direct the conversation to NASCAR and I'll be in Utopia.

Sorry to get back on topic:
Jason said the sleeve must be the entire depth of the hole. He did not say if the sleeve can be two piece.
ASTM 2170-11 / 6 (apparatus) says
"The liner shall have a solid sidewall that is only open at the bottom and top. Slots, holes or other penetrations in the sidewall...are not permitted. The liner shall...extend from the bottom diameter of the hole to the surface of the concrete"

So, reading into this; does that preclude a telescopic-type sleeve, as per JD's tank-buster analogy, to adjust for 40% of different slab thicknesses? I would think it doesn't.

Ah, this reminds me of my motorsport days, in what you folks would call "shifter karts". Our team developed our own karts, and we would push the regulations to the limits, taking advantage of any ambiguous wording. It would frustrate the rulemakers no end, because they had to keep going back and re-writing the rules. It happens at all levels.

RE: ASTM 2170-11
Well, to be honest, ours technically weren't "shifter", they were non-gearbox, but we raced with the shifter karts, i.e. on long circuits not kart tracks. The generic name we use for the whole range of road-race karts is "superkarts".

Our little NGB 125's would do 180km/h, and a bit, at places like Phillip Island. But then the 250cc (Shifters) would blow past like we were stationary. It was a great reminder that you were alive.

I understand these shenanigans go on a bit at Laguna Seca among other places.

Anyhoo, back to my point: The standards have to be specific. When it gets to mediation, ambiguous wording will be punished. In motorsport, it was the competitors who got punished!

RE: ASTM 2170-11
Wow, that's 112 mph in the states.... Way too fast on something with a 4 foot wheel base... Exclamation

We have a lot of lawyers here that make a good living due to ambiguity. If the standards are different than the manufacturer's specs, who do you follow? Say a manufacturer demands 75% RH or their glue will be damaged, and the spec says 80% is fine. Of course you will follow the manufacturer's spec right?

Now you guys are starting to talk my language--KARTS!! I know I shouldn't fuel this fire but I have 2 of the smaller 80cc gearbox's. Yes they are way toooo fun. I have also run some 100cc direct drives. You can't beat the rush for the money. Ok, now will you all get back on topic!!! Big Grin

error "I was told that the astm reference equipment is vaisala."

Was told that when ASTM does standards the equipment testing is based on is the vaisala. But I view that stuff as more lab equiopment. Damn sensors cost like $300 each.

You can see in the other thread with like to Craig's presentation lots of vaisala equipment in the lab.

RE: ASTM 2170-11
While they may use some fancy pants French equipment to verify testing methods while creating the ASTM, I would not hesitate to put my Wagner Rapid RH probes up against them where the rubber meets the road.

In fact, in the field, I would much rather have my Wagner's!
