Tested per standard. Proven per sample.

A note on language first, because this industry abuses it: ISO 22883 and the EN 12527–12532 series are specification and test-method standards for casters and wheels — they define dimensions, requirements and how performance is tested. ANSI ICWM standards do the same work in the US market. When we say a caster is built to and tested per these standards, that is a statement about the framework its specification follows and the methods its sample was tested by. It is not a certification claim, and you should be suspicious of any caster supplier who presents test-method standards as certificates.

The sample protocol

1. Dimensional verification. Wheel diameter and wheel width measured (width is both a performance and a tariff variable), overall height, plate pattern or stem dimensions checked against the locked specification.
2. Material verification. Tread hardness measured against the stated Shore range; stainless grade confirmed per component on the stainless line; core and fork materials checked against the specification.
3. Component verification. Bearing type confirmed as specified; fork and top plate thickness measured in millimetres; brake operation tested where fitted.
4. Load testing. Dynamic and static load performance tested per the stated convention (EN 12532 / ANSI ICWM), at the rating the quotation claims — including, for the high temperature line, bake testing of the assembled caster before any temperature rating is stated.
5. Approval and retention. The approved sample is the reference standard for the order; bulk production is checked against it.

Batch traceability

Each production order carries batch identification that ties the shipment back to its production run and its approved sample. If a question arrives with a shipment — a dimension, a hardness reading, a field failure — it is answered against records, not recollections. Buyers running private label programmes (see OEM) receive the batch references with their order documentation.

What we do not do

• We do not display other companies' test reports or certificates as if they were ours.
• We do not publish performance figures — temperature ratings, capacities — that have not been produced by testing the actual configuration being sold.
• We do not substitute materials or components against a locked specification without raising it before shipment.
