RATIO PROCEDURE
RATIO PROCEDURE:
1. Insure the mix tube is not attached to the mix cartridge. Open both the ISO (A) and
POLYOL (B) ball valves, take a “short shot” (2–3 seconds) to clear the lines. Reset Timer.
2. Close the POLYOL (B) ball valves and keep the ISO (A) ball valves OPEN.
Take a 10-second shot of ISO into a plastic bag and tie shut immediately.
3. Reopen POLYOL (B) ball valves and take a second “short shot”. Reset Timer.
4. Close the ISO (A) ball valves and keep the POLYOL (B) ball valves OPEN. Take
a 10-second timed shot of POLYOL into a plastic bag and tie shut immediately.
5. Open the ISO (A) ball valves, take a third “short shot”. Reset Timer.
6. Place gun on stand, attach muffler and air purge for 30 seconds.
RATIO:
The weight comparison of the output of ISO (A) to the output of POLYOL (B).
Necessary items:
• 30 gallon or larger plastic bag
• Gram scale
• Calculator

RATIO CALCULATION:
(Gram weight is necessary for accuracy.)
Ratio = ISO (A) : POLYOL (B)
Formula: ISO (A) Weight x 100
:
POLYOL (B) Weight x 100
ISO (A) Weight ISO (A) Weight
Example: 10 second shot:
ISO (A) weight = 1350 g
POLYOL (B) weight = 1260 g
1350g x 100
:
1260g x 100
1350 g 1350 g
1 x 100 : 0.93 x 100
100 ISO (A) : 93 POLYOL (B)
