NAC590.010. Adoption by reference of specifications for antifreeze; additional specifications.

Except as otherwise provided in NAC 590.030:

     1. The specifications for antifreeze based on ethylene glycol and the specifications for antifreeze based on propylene glycol contained in Volume 15.05, “Engine Coolants,” of the 2001 Annual Book of ASTM Standards, ASTM designation D3306-00a, are hereby adopted by reference.

     2. The chemical and physical properties of any antifreeze other than those classified in subsection 1 must be:

Water, mass %.............................................	5 max
Specific gravity 60°F/60°F..........................	1.11 to 1.15
pH (33% by volume) 7.5 to 11...................	7.5 to 11
Equilibrium boiling point............................	300°F min
Freezing point, 50% by volume..................	-34°F max
Foaming test
Increase in volume at 5 minutes.............	150 ml max
Break time...................................................	5 sec max

     3. In addition to the properties listed in subsection 2, any antifreeze other than those classified in subsection 1 must meet the following specifications for corrosion (loss of weight per specimen):

Copper.........................................................	10 mg max
Solder..........................................................	20 mg max
Brass............................................................	10 mg max
Steel.............................................................	10 mg max
Cast iron......................................................	10 mg max
Aluminum....................................................	30 mg max

     4. Any other test method may be used if the State Sealer of Consumer Equitability determines that another method produces results equivalent to the results of the specified method. A method approved by ASTM International that has not yet been published shall be deemed to meet the appropriate criteria.
