Test-item scoping, sample preparation and submission routes for ISO 7176, EN 12184, FDA 510(k) and CE-MDR — written by the engineers who run the tests.
The difference is not smaller dimensions. It is dummy selection, the configuration dimensions are measured in, and adjustment range convergence.
2026-08-28A stair climber is not a wheelchair plus tracks; stairs are a separate scenario. Scoping test items by mechanism type before the sample ships.
2026-08-27A standing or lift mechanism rewrites the chair's centre of gravity and stoppable postures. How to scope test items before the sample ships.
2026-08-26How to judge whether an existing wheelchair test report works for FDA and CE filings, and how to plan one test programme that serves both routes.
2026-08-22Scooters and powered wheelchairs share one standard set but need different test plans. Here is how stability, braking, seating and sampling differ.
2026-08-21A walking table carries body weight through the forearm platform. Here is how that changes strength, stability, brake reach and sample prep.
2026-08-20Most wheelchairs reach CE marking by self-declaration. This guide shows what actually triggers a notified body and what evidence each route needs.
2026-08-19ISO 7176-15 governs disclosure, not test methods. How to split information between permanent labels and accompanying documents.
2026-08-18Why the test dummy size locks fixturing, sample count and test order under ISO 7176-11, and how to derive it from your product claims.
2026-08-17How load travels from grips through height-adjustment tubes to ferrules, which details drive rework, and what to prepare before testing.
2026-08-16ISO 7176 reports say nothing about skin contact. How to list contact parts, set the ISO 10993 route and run it alongside ignition resistance.
2026-08-15Seat and wheel dimensions follow ISO 7176-7, overall dimensions ISO 7176-5. How to pick the right set and agree the setup before testing.
2026-08-11ISO 7176-31 references IEC 62133-2 for cell and pack safety. How the three report layers divide up, and what to submit for each.
2026-08-10What actually drives a wheelchair NMPA registration test list, how to derive items from product features, and what to prepare before testing.
2026-08-09Where powered wheelchairs fail obstacle-climbing tests, stage by stage, and the boundary conditions to lock down before samples ship.
2026-08-08ISO 7176-9 lands late in most powered wheelchair projects. Where to slot climatic testing, which samples can be shared, and what to fix first.
2026-08-07ISO 7176-4 reports a calculated theoretical range, not a measured ride. How to pick the submission build, word the manual and know when to retest.
2026-08-06If your manual or tender says the chair may be occupied in a vehicle, this test is unavoidable. Applicability, coverage and preparation.
2026-08-05Testing before documentation is how wheelchair EU MDR files fail: the reports do not cover the lead model. Families, reuse and gaps.
2026-08-04Picking a predicate on visual similarity is how wheelchair 510(k)s go wrong. Three gates to clear, and what a public summary will not tell you.
2026-08-03ISO 7176-14 covers power and control systems under misuse and fault conditions, not just normal use. Where it ends and EMC, braking and battery parts begin.
2026-08-02ISO 7176-16 covers postural support devices only — cushions, straps, armrest pads — not wheels or frames. What is tested and what to send.
