THROUGHPUT PROCEDURE
THROUGHPUT PROCEDURE:
1. Attach mix tube and secure with mix tube collar.
2. Take a timed shot into a plastic bag, as follows:
10-second shot for 6-PPM, 15-PPM or 30-PPM.
6-second shot for 45-PPM
5-second shot for 60-PPM
3. After shot, place gun on stand, attach muffler and air purge
for a minimum of 5 minutes
.
4. Wait 5 minutes to allow foam to cure on a warm flat surface.
5. Weigh the foam bag on a gram scale and record weight.
THROUGHPUT:
The number of pounds per minute (PPM) dispensed from the SLUG PRO dispensing unit.
It is the weight of foam from a 10 or 6 second timed shot expressed in lbs./min.
Necessary items:
• 30 gallon or larger plastic bag
• Scale
• Calculator
CALCULATIONS:
(Gram weight is necessary for accuracy.)
454 grams = 1 pound
a) 1135 g
= 2.5 lbs
454
b) 2.5 lbs x 60
= 15 lbs/min
10 sec
c) Throughput = 15 lbs/min (0.25 lbs/sec)
a) Weight in grams
= Weight in lbs
454
b) Weight in lbs x 60
=
Weight in lbs
10 seconds 1 minute
c) Throughput = Weight in lbs/min
Formula:
Example:
A 10-sec. shot from a 15-PPM gun unit weighs 1135 grams.
