The specification below provides the recommended improvements needed to improve product durability. They are ranked from bronze to gold based on the effectiveness of the change in improving durability, with bronze being the minimum and gold being the maximum.
Replaceable seals; antibacterial coating; specified door loading; specified for 38,000 openings / slam-shuts
Reversible door; specified for 49,000 openings/slam-shuts
Specified for 60,000 openings/slam-shuts
Look for poor seal quality/fit and any weak aspects of the door assembly
Ask for clear evidence of meeting the requirements listed above to be provided e.g.:
Door load test method: 10 units to be tested for the number of openings and closings, with 30kg loading evenly across the door shelves without damage or failure or significant deflection or sag (>2mm in any direction) to door, hinges or shelves in 100% of cases.
BS 6222 should inform the door hinge test.
The door seal air tightness test should reflect the EN62552 Household Refrigerating Appliances standard.
# WRAP research suggests that consumers expect a lifetime of 8 years.
Improved reliability of components can reduce early returns and improve brand reputation which, in turn, can lower business costs and increase long-term sales.
To calculate overall cost savings for your business, use the WRAP cost/benefit analysis tool (currently in draft form and available on request).
Anti bacterial coated door seal
Antibacterial coatings are widely used and help reduce the occurrence of mould.
Basic door strength (testing for 27,000 openings)
A basic design to last at least 7 years, with the required testing.
Replaceable door seal
Having a replaceable door seal could involve using a new door liner mould to produce the groove for the seal to fit into and a different seal profile to match it.
Stronger /longer lasting door hinges (38,000 openings)
To obtain 9 years’ life, a higher specification such as increased leaf thickness, larger fixing screws and improved bushes can be used.
Having a reversible door will add some extra drillings and extra metal plates and bushes.
Stronger/longer lasting door hinges (49,000 openings)
A higher specification still may be required to ensure that the door lasts for at least 11 years.
