Shower tray and wet-room floor testing is a specialist area — the combination of wet barefoot use, soap contamination, and small surface area makes conventional BS 7976 / BS EN 16165 testing impractical. DIN 51097 barefoot ramp testing is the appropriate standard.
The pendulum test requires a minimum surface size and is designed for shod footfall. Shower trays — small, textured, used barefoot — need the DIN 51097 ramp test instead, where a tester walks on a soaped, inclined sample until slip occurs.
DIN 51097 produces three classifications: Class A (minimum), Class B (barefoot wet commercial), Class C (wet barefoot with elevated risk — typically pool surrounds and high-end shower products). Most residential shower trays achieve Class A or B; commercial specifications typically require Class B or C.
Shower tray manufacturers use our laboratory certification for product marketing, specification submissions, and retailer acceptance. We work with UK shower tray manufacturers across the residential and commercial price points.
Pendulum testing requires minimum surface size and is designed for shod footfall. Small textured shower trays used barefoot need the DIN 51097 ramp test instead.
Most commercial specifications require Class B or Class C. Domestic products typically achieve Class A or B.
Yes — we work with UK shower tray manufacturers across both domestic and commercial product lines for DIN 51097 certification.
