SECTION 165:16-5-2. Testing of methanol type antifreeze

  The American Society for Testing and Materials (ASTM) standards shall be used to make the following tests of antifreeze.

(1)   Boiling point test. The boiling point of an antifreeze shall be determined by the ASTM designation D-1120 (2016) test. The boiling point of a concentrated antifreeze when added to the cooling system of a motor vehicle at atmospheric pressure shall not be below 133° F or 56° C.

(2)   pH test. The pH of an antifreeze shall be determined by the ASTM designation D-1287 (2011) test. The pH of an antifreeze shall not be below 7.5. The pH of an antifreeze shall be run by using a solution composed of 50% concentrated antifreeze and 50% water, by volume.

(3)   Reserve alkalinity test. The reserve alkalinity of an antifreeze shall be determined by the ASTM designation D-1121 (2011) test. The reserve alkalinity shall not be below 10.0.

(4)   Freezing point test. The freezing point of an antifreeze shall be determined by the ASTM designation D-1177 (2016) test. The freezing point of the various water antifreeze solutions shall be such as to protect according to the chart in Appendix B of this Chapter.
