can any tell me what IMC table 1202.4 shows?

I Googled "International Mechanical Code Table 1202.4". That returned a pdf taking me to the text and the table. I assume you are interested in PE pipe; for it there are listed 8 ASTM standards for the pipe. I'd paste them here but the PC I'm on now doesn't support the selection tool normally available when viewing a pdf.

ASTM.org supports searches on their various standards.

My guess is you'd want pipe and tools to work with it to be compliant with the relevant underlying ASTM standards.

State codes incorporate by reference international codes, international codes incorporate by reference ASTM standards.

Hope this helps...

Thanks, Curt. You pointed me in the right direction

It's one of those code passages that tells you nothing except where to look for the code.
It covers not only HDPE test methods and required burst and tensile strengths but fusion methods, tools and the requirement that the pipe be made of "virgin plastic".
Much of this is covered in igshpa training, though not necessarily cited by name.
Most inspectors are not even aware of this section of the code, so what the heck brought it up?

A new engineer included in on the plans for the job that we are currently drilling.

Thanks for the summary

Engineers sometimes add needless complexity.

With any luck, your pipe and tool suppliers will be able to certify relevant ASTM standard compliance, sending the offending engineer back to his / her cubicle.

"A new engineer included in on the plans for the job that we are currently drilling."

Gotta love boiler plates (for those unfamiliar it is an extra page on the blueprints that essentially says to do everything you're supposed to do). I can't imagine where you'd find non-complying HDPE.

You are a rarity among engineers to admit this.

Thanks for the time you spend on the forums.

Thanks Joe

I have been guilty, upon occasion, of injecting needless complexity.

Nowadays, whenever tempted to do so, I try to ensure I'm the sole victim of the results, that is, I'm experimenting and will face the consequences alone.

As for admitting guilt, I came cross a quote, possibly by Samuel Clemens AKA Mark Twain: something along the lines of:

"Always admit mistakes, quickly and without reservation. It confounds your adversaries and clears you to make more mistakes"

I must concurr. It has allways been my position to face my mistake or oversight head on. It has left more than one engineer, and general contractor with that look of utter dis belief. It also serves to diffuse potentially explosive meetings in that white job trailer.

Looking at the issue from another angle - the alternative to admitting mistakes, making them right and moving on is defending a stance and position that you know, deep down, is untenable.

That's what we have come to expect of politicians, lawyers, and marketers, none of whom garner much respect these days. What team do you want to be on? What story would you rather tell your friends, neighbors, relatives and kids - the foulup that taught you something or the loud but hollow defense of an action or shortcut you knew to be wrong?

Eating a bit of crow and spending a few bucks or hours (or days) to fix an error lets you sleep well and hold your head high.
