Calibration System for Shot Bag Impact Test Equipment (JIS R 3110: 2021 Compliant)
Strain gage measurement is now mandatory for verifying the integrity of test equipment used in glass safety evaluations.
We offer a comprehensive range of strain gages and measuring instruments that fully meet these updated requirements.
Due to the JIS revision, it is now mandatory to use 2-axis or 3-axis strain gages to verify the integrity of shot bag impact test equipment. By using our strain gages and measuring instruments, you can achieve equipment calibration that fully complies with JIS standards.
What is the Shot Bag Impact Test?
This test evaluates the safety of flat glass by striking it with an impactor of a specific weight at a designated velocity to measure the extent of breakage. By conducting the test using equipment and methods prescribed by JIS, evaluations can be performed under uniform standards, regardless of the person conducting the test.

System Configuration Example
By using our strain gages and measuring instruments, you can perform test equipment calibration that fully complies with JIS standards. We offer a simple system configuration that is easy to use, even for those new to measurement.
POINT1: Strain Gages
By using multi-axis type gages—which consist of multiple pre-stacked elements—you can measure strain in several directions with a single strain gage. 2-axis gages measure horizontal and vertical strain, while 3-axis gages add a 45-degree direction. Additionally, with 3-axis strain gages, the magnitude and direction of principal strain can be determined through rosette analysis.
POINT2: Measuring Instrument
This measuring instrument features a simple configuration and easy setup. With a built-in bridge circuit, Strain Gages can be easily connected via an input adapter, making it highly user-friendly even for beginners. The 4-channel support allows for simultaneous measurement of both horizontal and vertical data with a single unit.
Calibration Procedure Example
STEP1
Adhere the strain gages onto the reverse side of the glass panel used for calibration.

Perform a single-impact drop targeted at the center of the glass. Measure and record the horizontal and vertical strain for a total of three trials.
STEP3
Confirm that the data falls within a ±10 % range of the reference calibration curve.
