Weathered clothes pegs lose two-thirds of their working life, testing finds

Life testing of 720 domestic clothes pegs at the School of Emergent Priorities has given a strata-services contractor the retirement interval it will apply across 41 communal drying courts, whether or not a peg has stopped gripping.

A strata contractor will now retire every peg on its communal drying courts at a fixed interval set by the laboratory result

The ordinary things are the ones nobody has got around to characterising, and that is exactly where a school like ours can be useful.

Cycles to Failure in Weathered Domestic Clothes Pegs, a research poster released today by the School of Emergent Priorities, sets out what is understood to be the first controlled life test of the commodity clothes peg. Seven hundred and twenty pegs across five designs were held under xenon-arc exposure for 600 hours, then cycled open and closed under a fixed line load until each one failed.

The study brings a reliability posture to an object that has never carried one, and translates a laboratory result into a setting a maintenance team can act on. Median life fell from 2,610 cycles unweathered to 968 after exposure, and the pooled B10 figure of 538 cycles has since been adopted by a strata-services contractor as the retirement interval for every peg across its 41 communal drying courts — a schedule that retires nine pegs in ten while they are still holding.

Dr Anneke Tolan, Senior Research Fellow, said the uptake had come sooner than the team expected. “Somebody had a use for it before we had finished writing it up,” she said. “That is not always how these things go, and we are glad of it.”

The University regards the work as an example of the unglamorous characterisation it intends to keep supporting, and as a demonstration of what the School’s anticipatory agenda looks like applied to a physical component.
