2026-05-27 Energy Conservation Program: Notification of Petition for Waiver of Zhuhai Samyou Environmental Technology Co., Ltd. from the Department of Energy Walk-In Coolers and Walk-In Freezers Test Procedure and Notification of Grant of Interim Waiver; Notification of petition for waiver and grant of an interim waiver; request for comments

Heatcraft, a manufacturing company, opposes specific modifications to test conditions and tolerances in the proposed alternative test method. They argue that these changes would weaken measurement rigor and should instead be developed through a formal industry-wide process.

The commenter argues that the petition for a waiver is insufficient because it lacks technical evidence, such as engineering drawings and validation data, to support the claims of design constraints. They also note that the petition fails to provide specific documentation regarding economic hardship or address concerns about the rigor of the proposed alternative test methods.
