Product Made in Japan
Manufacturer: Ultrasound
Model: JIS Z 2329

Feature:

The foaming liquid used is tested under the default foaming pressure (differential pressure from atmospheric pressure, 5×103 Pa) or less.
The test specimen is attached to a container with small holes (5 mm dia.) or a test plate using adhesive aluminum foil tape to cover the small holes.
In the case of the pressurization method, the minimum foaming pressure at which foaming occurs through the holes in the specimen is checked by sequentially applying pressure.
For the vacuum method, the test plate to which the specimen is attached is covered with a vacuum box and evacuated, and the minimum foaming pressure at which foaming occurs through the holes in the specimen is checked.

Specification:

Name: BL 30/100
