Overview of 2011 S&L Compliance in Australia and New Zealand
This report presents the results of verification tests conducted from January to June 2011. Verification testing, or check testing, is often conducted to verify the performance of appliances and equipment regulated for energy efficiency in Australia and New Zealand.
The two relevant types of regulatory programs are Minimum Energy Performance Standards (MEPS) and Mandatory Energy Labeling, both of which are part of the Equipment Energy Efficiency (E3) program.
The check testing process comprises two stages:
Stage 1 test (also known as the screen test) performed on one sample of the model. This sample is generally independently purchased (usually through a retail outlet), paid for by the regulatory authority and tested by a laboratory accredited for check testing; and
Stage 2 test performed when a model is found to be non-compliant. The supplier will then has the choice of either cancelling the registration for the model or proceeding to stage 2 check testing. Stage 2 involves the testing of either two further units (where the failure relates to performance standards) or three units (where failure relates to a ‘supplier declaration’ i.e. claims on labels), paid for by the registration holder.
From January to June in 2011, 75 check tests were completed for six product categories, including air-conditioners, clothes washers, electric motors, refrigerator/freezers, televisions, and set-top boxes.
Overall, 92% of products tested were judged by regulators to comply with energy regulations. This is relatively high compared to the results from longer term analysis of previous years. For example, the overall compliance rate for the period 2004/5 to the end of 2010 was 84%.
Set top boxes and electric motors were found to have the highest compliance rates, while the lowest compliance rates were evident in televisions and air-conditioners (as shown in the figure below). However, due to the very small sample sizes within each product category, the differences in compliance rates are not considered to be significant.
