what does CA mean here?

Question

The abbreviation of CA appears in the description of contents of the petroleum coke which go as follows:

Moisture: 9% max.
Sulfur: 2% max.
Volatile content: CA. 8-12%
Hardgrove Grindability Index: CA. 36-46
Gross Calorific Value: CA. 14,000 BTU/LB TYP.

I guess that CA might indicate that the content may vary within a range. But I have no idea specifically as to what CA stands for.

Shall appreciate your kind input.

Thanks,

Vincent

ca

Means approximately. It should be written in low case, maybe that was confusing

The only word I could imagine would be "circa".

Here is the definition from Dictionary.com:

–preposition, adverb about: (used esp. in) approximate dates: The Venerable Bede was born circa 673. Abbreviation: ca, ca., c., c, cir., circ.

Lakshwadeep · Answer

I also think it is "circa", and it would have been better if the wrote it as "ca." instead of "CA." since the capital letters are not needed.
