measured using a slide caliper. Next, the ultrasonic device (Olympus 37DL fitted with a 5.0 MHz transducer) was used to measure the thickness of each specimen, as shown in Figure B-3. Figure B-1.

Mean thickness values for each control specimen are shown in Table B-2. From the data, it can be seen that the ultrasonic gauge works well when the specimen is well impregnated in resin (2.0 lb/ft or higher resin content), but does not provide a reading when the resin content falls to 1.5 lb/ft.

This is attributed to the absorption of acoustic energy by the material. The device also did not provide a reading when used on an improperly cured liner, as shown in Figure B-4. Figure B-4. Ultrasonic Thickness Measurements on Improperly Cured Liner The device worked well in the case of a PVC liner. A SDR35 PVC pipe was used. When measured with a slide calipers, average thickness value was 0.187". Using the ultrasonic device, the thickness found was 0.182-in. to 0.183-in., as shown in Figure B-5. Figure B-5.
