The Japanese Industrial Standard JIS C 1515:2004 for acoustic calibration was updated from the 2004 version to the 2020 version in January 2020.
JIS C 1515:2020 is a Japanese Industrial Standard created based on IEC 60942, which was published in 2017, without changing its technical content or structure. Therefore, starting with shipments from April 16, 2020, the nameplate markings have been changed to reflect the revised JIS standard markings.
For customers using the SC-2500 acoustic calibration that has already been shipped (shipped before April 16, 2020)
Customers who wish to update their JIS (Japanese Industrial Standards) markings should request calibration from us (for a fee).
After receiving your SC-2500 acoustic calibration, we will perform calibration and inspection at our company and update the notation to the revised JIS C 1515:2020 standard.
If you have any questions, please contact us (Customer Service Department or your nearest sales office).
