SAE J1399-2011 Electric Tachometer Specification – Cancelled and No Longer Maintained
Standard Overview
Originally issued in 1982, SAE J1399-2011 defined performance and testing requirements for electric tachometers used in surface vehicles. The standard covered essential specifications such as accuracy, input signal range, and environmental tolerances, providing a common reference for manufacturers and suppliers.
Cancellation Details and Current Status
In July 2011, the SAE Controls and Displays Committee officially cancelled SAE J1399-2011. The decision was made because the standard was no longer in regular use and no committee member was willing to maintain it. Cancelled standards remain available for purchase but are not updated or supported.
| Attribute | Detail |
|---|---|
| Standard | SAE J1399-2011 |
| Title | Electric Tachometer Specification |
| Issued | 1982-09 |
| Cancelled | 2011-07 |
| Reason for Cancellation | No longer in regular use; no committee member willing to maintain |
Important Note: While the cancelled document is still accessible for historical reference, it should not be treated as a current or active specification. Engineers must verify the applicability of cancelled standards before incorporating them into new designs.
Design Guidance for Tachometer Systems
🛠️ The cancellation of SAE J1399-2011 indicates that the practices it covered are obsolete or have been superseded. For new tachometer designs, engineers should consult active standards such as SAE J678 (if applicable) or other relevant industry specifications. Always confirm the status of any standard on the SAE website before referencing it.
⚠️ Caution: Relying on cancelled standards can lead to non-compliance with current regulatory or industry requirements. Always use the most current version of a standard for design and certification.
