Supermarket cabinets – latest testing news

Supermarket cabinets – latest testing news

Firstly we wanted to let you all know that in light of recent lockdown announcements, we can reassure customers that RD&T is open for business. The safety and wellbeing of our staff and customers is of the highest priority, so we have adopted all necessary social distancing measures and the site is confirmed as a ‘Covid-Secure’ workplace. We are therefore still carrying out testing work at our facilities as well as desk-based work from home.

Although everyone’s focus has been very much on the current pandemic the countdown to eco-design and energy labelling is continuing with only 3.5 months left before supermarket cabinets need to comply with this new legislation. If selling into Europe, manufacturers must list equipment on the European product database for energy labelling (EPREL). If selling within the UK, there must be a link to a product information sheet on a publicly accessible website. One way that manufacturers can ensure that accurate and robust data is submitted, is to either test cabinets independently or to obtain an independent witness test (this can be done remotely as well in person). This provides evidence to compliance authorities on the validity of the claimed cabinet performance. RD&T have developed robust witness testing protocols that can be used for remote (or if applicable, in person) validation of tests to help companies make sure that they have clear evidence of compliance with eco-design and labelling regulations.

As part of the new regulations, the test standard that is used for testing most supermarket cabinets (BS EN ISO 23953: 2015) is being updated. RD&T’s Judith Evans is the BSi representative on CEN/TC 44/WG 1 (Commercial refrigerated display cabinets) which is responsible for the updates. These include:

  1. Updates to the total display area (TDA) calculation where there are inconsistencies and lack of clarity
  2. Clarification on sensitive foodstuffs loading
  3. Definitions of semi-vertical cabinets
  4. Measurement method for water-cooled condenser cabinets
  5. Use of refrigerants with glide
  6. Application of multiple load lines
  7. Rules for representative cabinets and use of alternative components
  8. Test room ambient measurement positions
  9. Extending the scope so that it excludes other new standards (e.g. beverage coolers)
  10. Mass flow measurement under unstable flow (e.g. use of EEVs)

This work is ongoing with an outline plan for the standard to be available for consultation around the middle of 2021.

In addition, there is ongoing parallel work to migrate the EN standard to an ISO standard. This is being carried out under ISO/TC 86/SC 7/WG 3 (Commercial refrigerated display cabinets) and again Judith Evans is involved as the BSi representative. The committees are currently quite active with regular web-based meetings to push forward with the updates. If you would like further information, please contact Judith at RD&T (
