PERFORMANCE NEEDS CONTEXT
“Tested” should start
a better conversation.
Ask which assembly was tested, in which direction, at what length, with what fixtures and acceptance criteria.
THREE DIFFERENT QUESTIONS
Pulling is not the same as pushing.
| Test direction | What it examines | What to ask |
|---|---|---|
| Tensile pull | Force through the engaged head, connection, shaft and handle. | How was the head engaged? Which assembly and length? |
| Compressive push | Axial compression and possible instability of the shaft. | Was alignment controlled? What unsupported length was used? |
| Bending / off-axis | Behaviour under an offset force or moment, where relevant. | What offset, restraint and acceptance criteria applied? |
PROOF LOAD & OPERATING LIMITS
A proof value is not automatically a working rating.
A test result describes a configuration and a method. It does not establish unlimited use in every application.
Ask whether the value is a proof test, destructive result, material property or rated operating limit. A whole-tool value should identify the tested configuration and the basis for the permitted use. Do not use magnet pull-off force, shaft strength or a single component result as a rating for the complete assembly.
Compression performance can depend strongly on unsupported length, alignment and end conditions. Pull performance depends on engagement and the load path through connections.
PURCHASING CHECKLIST
Request evidence you can connect to the tool.
- Exact model, length, head and insert identification.
- Test date, report reference and sample traceability.
- Fixture arrangement, force direction and unsupported length.
- Applied load, duration, observations and acceptance criteria.
- Declared operating limits and instructions for use.
- Scope of coverage across other lengths and variants.
Request current model-specific PSC documentation with your quotation. Published test values should be read with their method and limitations.
