A: In most cases, no — a single well-designed test platform can serve multiple standards. The DR-J501 and DR-J601 are built with this multi-standard flexibility in mind. The mechanical architecture — load frame, actuator, load cell, fixturing — remains constant. What changes between standards is the test recipe: applied force values, cycle counts, loading pad geometry, hold times, and pass/fail criteria. These are all software-configurable parameters stored as named test programs on the machine’s PLC.

For example, the DR-J501 sofa/chair durability tester can run EN 12520 domestic seating tests, BIFMA X5.4 lounge seating tests, and Chinese GB/T 10357.3 chair tests — all on the same hardware, switched via the touchscreen in under a minute.

That said, there are limits:

• Loading pads differ: BIFMA, EN, and ASTM sometimes specify different loading pad diameters and shapes. We supply a set of standard-compliant interchangeable pads with each machine.
• Some standards require unique test rigs: ASTM F1566 (Cornell mattress test) uses a specific 240-lb hexagonal roller not found in EN 1957. If you need both, the DR-J503 can accommodate different roller attachments, but you’ll need both roller assemblies.
• Fixture compatibility: Chair base fixtures for BIFMA X5.1 swivel testing differ from those for EN 1335. We include the fixtures for your primary standard and offer additional fixture kits as options.

Bottom line: tell us which standards and markets you need to serve during the quotation phase, and we’ll configure one machine with all necessary software programs, loading pads, and fixture adapters.
