I am excited to host my first technical committee meeting on IEC 60335-2-40. It is in technical committees such as these where the initial steps for manufacturers are made before finally casting into steel the claims for their equipment. Often these claims contains information on the greenhouse gas emissions from the equipment during operations based on test and performance validation results.
I guess I have issued over a hundred audit findings related to equipment nameplates. Nonconformities ranging from content mismatch with environmental permits to physical damage to the nameplate during routine maintenance (painting, etching or losing its entirety).
With climate change as a pressing issue of global importance, I believe that its also high time for us to give a high regard for equipment nameplates. Who reads nameplates anyway?
GHG verifiers are trained to read equipment nameplates with an assumption that the nameplate rating is the best record of measure of the performance of the equipment. However, nameplate ratings are still estimates based on the accuracy and precision of the performance validation tests and a certain degree of uncertainty is still involved in the nameplate rating. Moreover, a weak test validation system can allow manufacturers to make false claims, to the point of permanently etching it on the nameplate, but global good practice and intense conformity assessments make this practice outright dishonesty.
Every now and then, I would randomly look into appliance nameplates more than the other marks such as marketing stickers or even regulatory labels. Nameplates are a good ballpark estimate of the carbon footprint of the equipment.
