What is ASTM D6210?
ASTM D6210 includes all of the testing required for D3306, as well as additional testing that evaluates the performance of the coolant for heavy duty applications.
What is ASTM D3306?
ASTM D3306 and ASTM D6210 are today’s most commonly referred to industry standards for coolants. ASTM D3306 contains several tests that define requirements for light duty coolants. The specification measures key physical properties of the coolant like freezing and boiling points.
What percentage of antifreeze is propylene glycol?
Propylene Glycol – Water 33% V/V Water ASTM-D 3306 Max. The results above are an average change in weight of coupons in mg. A negative number indicates an increase in weight due to the formation of a stable protective layer on the metal’s surface.
Is propylene glycol a good coolant?
Propylene glycol is added to food and beverages to improve taste and texture. It is not antifreeze. It is considered safe to use in the amount present in foods.
What is ASTM D4985?
ASTM D4985 : Standard Specification for Low Silicate Ethylene Glycol Base Engine Coolant for Heavy Duty Engines Requiring a Pre-Charge of Supplemental Coolant Additive (SCA) IHS Markit Standards Store. by S&P Global. Item.
What is JIS k2234?
JIS K 2234:2018 specifies the antifreeze coolants (hereafter referred to as antifreeze coolants) mainly composed of ethylene glycol, which are employed for prevention of freezing of cooling liquid used in a liquid-cooled internal combustion engine (hereafter referred to as cooling liquid) and for corrosion prevention …
Are there different types of propylene glycol?
There are four main types of propylene glycols. They are Propylene Glycol , Propylene Glycol USP , Inhibited Propylene Glycol , Reclaimed Propylene Glycol and Dowfrost Glycol .
What antifreeze uses propylene glycol?
The addition of glycol antifreeze (such as Dowfrost HD™ propylene glycol, Dowfrost™ food grade propylene glycol or Dowtherm SR-1™ ethylene glycol) to water in hydronic heating and cooling systems, lowers the freezing point of your heat transfer fluid mixture.
What are the grades of propylene glycol?
Typical names are propylene glycol (PG) and monopropylene glycol (MPG). The propylene glycol can be manufactured in different grades. The most controlled grade is called propylene glycol-USP/EP and is manufactured and distributed according to high industry standards. The normal PG grade is called industrial grade.
What is another name for propylene glycol?
Other names for propylene glycol are 1,2-dihydroxypropane, 1,2-propanediol, methyl glycol, and trimethyl glycol. Propylene glycol is clear, colorless, slightly syrupy liquid at room temperature.
Is red antifreeze propylene glycol?
The purpose of using an antifreeze is to lower the freezing point and increase the boiling point of the coolant. The key difference between red and green antifreeze is that red antifreeze lasts longer than green antifreeze. An antifreeze contains ethylene glycol and propylene glycol as the bases.
