Do you have a specific question about something in the standard?

NSF/ANSI Standard 50 and the MAHC

The CDC's Model Aquatic Health Code specifies that commercial pool chemicals be NSF-50 or NSF-60 certified, or have an EPA Registration. Orenda already is.

More specifically, I'm looking for the L1, L2 and L3 water testing accuracy standards from Section O.12.

I HAVE L1, L2 and L3 for pH, FC and CYA...I'd like the rest.

 

[JamesW]

Water quality testing devices accuracy levels Section N-11.12 (formerly Section O.12).

It looks like the section is now N-11.12.

Do you need to know the accuracy of test devices for different chemicals?

 

[PoolStored]

I have the devices to the levels. I don't have the tolerance for the levels other than pH, FC and CYA...unless N changed them...Here is O.12 for pH as an example:

 

[JamesW]

Maybe ask Taylor Technologies or any test kit maker as they should know the requirements.

 

[JamesW]

Annex O.12 Accuracy Testing: Revised the accuracy level tables for pH, chlorine, and bromine and added new accuracy level tables for hardness, alkalinity, cyanuric acid, total dissolved solids and salinity as follows:
O.12.4 Accuracy levels for Hardness
O.12.5 Accuracy levels for Alkalinity
O.12.6 Accuracy levels for Cyanuric Acid
O.12.7 Accuracy levels for TDS
O.12.8 Accuracy levels for Salinity

 

[JamesW]

N-11.12.1 Accuracy levels for pH (range of operation 5 to 10).

N-11.12.2 Accuracy levels for

N-11.12.3 Accuracy levels for

N-11.12.4 Accuracy levels for Hardness

N-11.12.5 Accuracy levels for Alkalinity

N-11.12.6 Accuracy levels for cyanuric acid (range of operation 0 to 240 mg/L)

N-11.12.7 Accuracy levels for TDS

N-11.12.8 Accuracy levels for Salinity

 

[PoolStored]

Ha! Now I need the ranges...

 

[JamesW]

 

[PoolStored]

I have those!
