A new Slop University research poster bench-tests 386 appliances across 61 council community facilities and finds the failure rate almost identical whether or not the appliance carries a current test-and-tag sticker.
Bench-testing 386 appliances at 61 council facilities put the failure rate at 8.5 per cent either side of a current tag
There is a small coloured tag on the cord of the urn in most community halls, with a date on it and a signature. It turns out to say very little about the urn.
In Date, and No Safer, released today by the School of Continuous Improvement, put 386 portable appliances from 61 council community facilities on a bench and tested them to the full standard, with the tag covered so the electrician could not see it. One appliance in twelve failed. The proportion failing was 8.5 per cent among appliances carrying a current tag, and 8.7 per cent among those lapsed or missing one.
Nobody we met was doing anything other than what the schedule asked of them, and it is not a bad schedule. The narrower question we would put back is what any of us were entitled to conclude from the sticker, and who decided that.

The proportion of appliances currently tagged is reported to the council each quarter as an electrical-safety indicator, and across the study window it never fell below 93.6 per cent. Twenty-eight of the 33 failures were found on appliances that were in date at the time.
Dr Solveig Adeyemi, Lecturer in the School, said the year had depended on the people who run the halls. “Caretakers let us take their kitchens apart for months,” she said. “Several told us which appliance to look at first, and they were usually right.”
The University regards work of this shape — an assurance instrument examined against the thing it is taken to assure — as central to the School’s continuing agenda. The full poster is available from the University’s research repository under an open licence, doi:10.5555/slop.tyesio.
