Direct answer
A force value alone does not compare crush resistance. Match the tested object, contact geometry, support, load location, duration and temperature. Enclosure, connector and whole-cable reports are not substitutes for one another, and an intact appearance alone does not establish functional acceptance.
Definition and standard scope
Crush and load evaluation concerns the effect of specified external loads on a device. The public description of IEC 61300-2-10:2021 includes stepping, tyre loading and static loads on street cabinets. IEC scope
That scope does not authorize driving over every optical connector or assign a rating to an armored cable. Whole cables and protective devices require their own applicable methods and approved specifications.
Applications and load checklist
Use this review for outdoor protective devices, equipment housings and assembly installation points. Describe credible load locations before the design and test teams agree conditions.
| Object/condition | Review input | Why force alone is insufficient |
|---|---|---|
| Protective device | Model, cover and mounting state | Support and assembly affect loading |
| Contact | Geometry, position and direction | Different areas are different tests |
| Load process | Application and hold time | A peak misses the sequence |
| Environment | Temperature and conditioning | Evidence must match requirements |
| Acceptance | Deformation, operation and optical checks | Appearance is not complete function |
These are suggested report fields, not prescribed numerical limits. Tensile evidence also does not independently establish crush behavior.
Comparing reports
First compare the tested objects. A complete enclosure and a material coupon cannot be ranked by the larger force value. Then review support, contact, direction, duration and temperature. Record differences instead of copying a passing verdict.
Preserve mounting drawings, loading sketches, specimen revisions and before/after records. If internal routing may be affected, agree the optical observation and functional criteria in advance: which channels, at what stage and against which limits.
Procurement boundaries and safety
Evidence applies to the tested configuration and conditions. Changes to mounting, drawings or housing versions require an applicability review. A protective enclosure result does not independently rate every component inside it.
Do not step on or drive over specimens in an operating network. Use an appropriately capable test provider and the applicable procedure. No ARRANEX force rating, vehicle-load capability or crush certification is asserted.
Procurement FAQ
- Is a larger force always better? Make specimens and conditions comparable first.
- Does armor establish a crush qualification? Request the structure and applicable evidence.
- Does a tensile pass prove crush resistance? Different loads need corresponding evidence.
- Is no visible cracking enough? Follow agreed operation and optical criteria.
- What is useful in an RFQ? Drawings, mounting, load location, environment and acceptance boundaries.
