Once you have obtained the legitimate PDF, here is how to integrate it effectively:

The standard divides surface plates into several classes. For example:

The permissible deviation from flatness is expressed in micrometers (µm) per square meter. Smaller plates have tighter tolerances relative to their size.

Adhering to JIS B 7420 is important for industries that rely on precise torque application. Proper calibration and verification of torque wrenches help in:

No. While similar, you cannot relabel a plate as JIS B 7420 compliant without testing to the specific flatness criteria and marking requirements of the JIS standard.

The JSA is the primary publisher. You can purchase a DRM-protected PDF in Japanese or English.

They require a surface plate (typically granite) that meets the flatness tolerance for Grade 0 as defined in Table 2 of the standard. You will need a calibration certificate referencing that specific grade and standard. Once you have obtained the legitimate PDF, here
