Has anyone taken this EPA lately or anyone know the evacuation table?

Here is my dilema, I have the Mainstream, epatest dot com 2008 study material and interactive CD.

I am doing almost 100% correct on over 400 questions for the Core and Type I II and III.

There is a table in there for Evacuation Requirements that the EPA changed in 2004. The Very High Pressure and Low Pressure Refrigerants has not changed.

Its the High and Medium. The High is Formerly Higher and the Medium is formerly High.

The Examine floating around has not been updated since 1999 according to the representative I spoke to in Washington.

So what it comes down to I have memorized the current table but the exam will be targeted for the table before 2004 change.

My Question is, the current High category is R-410A, R-22, R-401B, R-402A/B, R-404A, R-407A/B/C, R-408, R-409, R-411A/B, R-502 and R-507A.

These would have an evacuation of 0 Inches of Mercury before or after Nov. 15 1993 by the current table. If over 200 Pounds of Refrigerant then its 4 inches before Nov 15 1993 and 10 inches after Nov 15 1993.

The Medium Pressure Refrigerants formerly ( High-Pressure), R-12, R-114, R-124, R-134A, R-401C, R-406A and R-500 would still have the same Evacuation Requirements on the test from what I read? Under 200 Pounds of Ref. and before Nov 15 1993 its 4 inches of Mercury and if Over 200 pounds its 10 inches of Mercury. After Nov 15 1993 its 4 inches of Mercury if under 200 pounds and 15 inches of Mercury if over 200 pounds.


From what my understanding is all the Refrigerants I listed the Current High catergory (Formerly Higher Pressure), would all those refrigerants go by the Medium ( Formerly High) Category EXCEPT for R-22 correct?

R-22 would have the exact same requirements before 2004 and now.

All the other refrigerants I listed with R-22 would fall under the Medium (Formerly High) Category.

Anyone know about this that can help me out?

I see some other tables in other study guides that say R-22 category and the other category is all others so I am assuming I am correct that R-22 has the same requirements as today's current table and all other refrigerant will fall under Medium (formerly High) Category. Except for Very high and Low those have remained unchanged as far as I know.

I am hoping someone here knows the answer to this because neither my Proctor who I will be taking the exam with, EPA department in Washington nor Mainstream really know the answer to this.

There are at least 5 questions on the EPA test that will refer to this table and I can see now I will get them wrong unless I straighten this out.

Thanks for taking the time to read my Post. Hope you can help?
