ASME Code question 1

[rmw]

I don't know if this question is proper for this forum or if it should be asked in Pat's Pub. But here goes.

For our code guru peers, I have this question.

Upon entering the men's room of a restaurant this evening, to do what will be obvious in a second, I noticed a tag on the urinal that stated "this device conforms to ASME Code A112.something.19.2something or so.

What part of the ASME Code does this refer to? And, when did we (I have been an ASME member for over 30 years) start doing codes and standards on urinals?

What is the design pressure and test pressure for a porcelain urinal?

rmw,
I would suppose the Design pressure will be based on the tallest person using the urinal as it would give the maximum "head". The test pressure I would suggest would just be a "service" test rather than a full proof test.

 

[panduru]

Just in case rmw was indeed serious. My guess is that

either:
the "U" Stamp pertains to the flush cistern,
or:
the tag which actually belonged to a certain user, [user's equipment, rather] dropped on the cistern. Of course, he didn't want to pick it up from there.

Other possibilities may exist.

If the somethings are filled in, it should be possible to identify the type of equipment.

Look up the standards on the web. ASME includes many pluming standards. The following are all A112.19.xx

Enameled Cast Iron Plumbing Fixtures-Errata - November 1996; Supplement 2 - June 2000

Vitreous China Plumbing Fixtures and Hydraulic Requirements for Water Closets and Urinals-Revision and Consolidation of ASME A112.19.2M and ASME A112.19.6

Stainless Steel Plumbing Fixtures (Designed for Residential Use)-Supplement: September 2002

Porcelain Enameled Formed Steel Plumbing Fixtures-Errata - November 1996; Supplement 1 - 1998; Supplement 2 - June 2000

Trim for Water-Closet Bowls, Tanks, and Urinals

Non-Vitreous Ceramic Plumbing Fixtures-Supplement 1: 2002

Dual Flush Devices for Water Closets

Wall Mounted and Pedestal Mounted, Adjustable and Pivoting Lavatory and Sink Carrier Systems

Electrohydraulic Water Closets

Six-Liter Water Closets Equipped with Dual Flushing Device-Supplement 1: 2003

That's a relief to know and use.

 

[metengr]

rmw;
Do you think one needs to have a stamp similar to an R stamp to repair it??????? (LOL)

 

[jte]

That's "R" for Restroom, right? Or would it be a "relief" valve? I don't often rest near urinals but I do experience "pressure relieving events".

Obviously, more Codes and Standards are needed in this application. In the "facility" provided by the company for which I work (located on the 4th floor of the building) the (pressurized) supply piping for the urinals is NPS 3 and the (atmospheric pressure at "facility" elevation) drain piping is NPS 2. Wanting the latest technology (of course) the valves are the "automatic" type that sense the presence of a "customer" and upon the departure of said "customer" effect a flush. The problem (obviously caused by lack of appropriate Standards) is that on occasion the automatic valves malfunction and do not close. When this occurs, in short order the supply overwhelms the drain capacity and the urinal soon overflows and from the 4th floor to 3rd floor to .....well, you get the picture. As we all know, stuff flows down-hill.

Obviously, ANSI should charter ASME to address the deficience of an appropriate regulatory document (please).

On another but similar issue, Kathy Kidder Jones has been trying for at least 15 years to have her invention of a female urinal adopted by the managers of buildings that include public facilities.

http://www.personal.psu.edu/students/p/h/phc12/toilet/female_urinals.htm

There is much complaint from the distaff attendees of functions held at public arenas regarding long line at facilities, but so far the obvious solution to the problem has been ignored. One can only hope that the offended females will either get behind (so to speak) Ms. Jones invention or will cease their shrill, albeit incessant, complaint.

Just a thought.

Regards, John.

Metengr,

I don't know, but is a "U" stamp necessary to use it.

Panduru, JLseagull has confirmed that I was indeed serious and given the correct references. Just a little out of my league, what with having dealt with things like "N", "U", "R" etc stamps all my career, I wasn't prepared to see an ASME tag on a urinal.

Thought the code guys would enjoy a moment of mirth pertaining to another aspect of our profession. I'm glad the ASME is out there for us code stamping toilets too. I can rest easy tonight.

Sooooo rmw,

Does your posting of 4/22/06 indicate that you are going to simply disregard the efforts of Ms. Kathy Kidder Jones to "level the playing field" in favor of sleeping well tonight? For SHAME. Get behind the inventor; Ms. Jonse obviously needs all the help she can get in establishing "potty parity" in the public facilities of the world. I certainly hope her efforts do not pi** off the ladies standing in line.

Maybe the ladies will revolt and simply (without invitation) abandon the lines and flood (so to speak) into the "Gents" for relief. What would a lady say under these circumstances - "I just wanted to come in and hang out with the gentlemen"...?

With tongue planted firmly in cheek, regards, John.

Typo Guys,

It was a "P" stamp.

 

[EdStainless]

I was expecting the "P" stamp comment a lot sooner in this thread.
