Chemical Resistance Test Procedures and Results
Chemical Resistance Test
Procedures
One sample of a black lab top, identified as "Tech ResinTM"
and measuring 14" x 24" x 1", was submitted to Pittsburgh Testing
Labs, laboratory # SPT-30154A, on May 21, 1993, by Lab Tech Fabricators
Inc. The sample was tested for chemical resistance as described
herein. It is recorded and on file as Project # 823-30112. |
The panel was placed on a flat surface, cleaned with soap
and water and blotted dry. Next, the panel was conditioned for 48 hours at
73 degrees Fahrenheit, plus or minus 3 degrees and 50% relative
humidity, plus or minus 5%. The panel was then tested for
chemical resistance using 49 different chemical reagents by one of the
two methods listed below. |
Method A - Volatile chemicals were tested by
placing a cotton ball saturated with reagent in the mouth of a 1 oz.
bottle and inverting the bottle on the surface of the panel. |
Method B - Non-volatile chemicals were tested by
placing five (5) drops of the reagent on the surface of the panel and
covering with a 25mm. watch glass. |
For both of the above methods, the reagents were left on
the panel for a period of 24 hours. The panel was then washed off with
water, cleaned with detergent and naphtha, and rinsed with de-ionized
water. The panel was then dried with a towel and evaluated after 24 hours
at 73 degrees Fahrenheit, plus or minus 3 degrees and 50% relative
humidity, plus or minus 5%, using the following rating system: |
|
0 |
No detectable change to the working surface |
|
1 |
Slight detectable change in color or gloss, but
no change to the function or life of the working surface |
|
2 |
Slight
surface etching or severe staining. |
|
3 |
Pitting, cratering, or erosion of working
surface material. Obvious and significant deterioration. |
