IEC 60601-1 Figure 33 Body Upper-Carriage Module Technical dimension drawing

The test principle is based on simulating a dynamic person-loading event on the support or suspension part of the ME equipment. The body upper-carriage module is used together with the required mass according to the safe working load defined for the equipment under test.

For applicable sitting-area conditions, the loaded module may be dropped from a defined height, such as 150 mm from the lowest edge of the foam to the support area, according to the relevant IEC 60601-1 test requirement. After the test, the equipment is checked to confirm whether basic safety and essential performance are maintained.

Typical Test Objects

Medical Beds

Medical beds often include patient support platforms, adjustable sections and loading areas that may be exposed to dynamic forces during normal use. The Figure 33 body upper-carriage module can be used as part of the mechanical loading evaluation for these support areas.

Examination Tables and Treatment Tables

Examination tables and treatment tables may experience impact-like loading when a patient sits down, lies down or changes position. This module helps laboratories apply a standard-related upper-body loading interface during IEC 60601-1 evaluation.

Treatment Chairs and Patient Chairs

Treatment chairs, dialysis chairs, dental chairs and similar patient seating equipment may require dynamic person-loading assessment. The module helps simulate upper-body loading on seating or support surfaces.

ME Equipment with Patient or Operator Support Parts

Some ME equipment includes platforms, suspension supports, sitting surfaces or structures intended to support an operator during normal use. If dynamic loading from a person can occur, the Figure 33 related test may be applicable.
