Attached you will find testing method 2-16 entitled "Deter mination of Gels (Becton-Dickinson)". This is a new method which replaces testing method 2-l6 entitled "Tinius Olsen Flow Evaluation" which is now an obsolete method. Please dis card the obsolete copy and insert the revised one into Section 2 of your Quality Control manuals.
The Index for Section 2 has been revised and is attached. This issue supersedes the one of October, 1970. Please discard the obsolete Index and insert the revised one.
A revision to the attachment to testing method 2-5 is attached also. Please discard the old copy.

TITLE: SCOPE:
DATE: May, 1972 METHOD NO.: 2-16
Determination of Gels (Becton-Dickinson)
This method is designed to check for the presence of unwetted resin and fibrous contamination in a Plastisol paste.
APPARATUS:
12-oz. Paper Cup Toledo Scale Lighting Mixer Desiccator 6" x 6" Glass Plate
Vacuum Pump
CHEMICALS: Sample to be Tested DOP
PROCEDURE: 1. To a tared 12-oz. paper cup add 50 gms of resin and 55 gms of DOP.
2. Stir with lighting mixer for 1-1/2 minutes. Add an additional 15 gms of DOP and stir for another 50 seconds.
5* Deaerate for 15 minutes.
4. Cast a 7-mil film with the drawdown blade on a 6" x 6" glass. Count number of gels in a 4-1/2" square.
REPORT:
The number of gels found in a 4-1/2" square. If any sam ple is over 18 gels,, let the paste stand for 1 hour and repeat the test.
