IEC 60670-1:2021 Clause 15.2 and 15.5 Electrical Enclosure Compression Test Apparatus

The LS-B21 electrical enclosure compression test apparatus evaluates the compression resistance and structural integrity of electrical mounting boxes and enclosures to verify compliance with operational requirements under specified environmental conditions and external mechanical loads. The apparatus subjects samples to preconditioning in a controlled temperature environment. Following thermal stabilization to ambient conditions, specimens are positioned between dedicated support fixtures, where a precisely controlled compressive force is applied and maintained for a predetermined duration. Upon test completion and subsequent load removal, deformation measurements are conducted after a specified recovery period to assess whether the enclosure exhibits permanent deformation or structural damage that compromises functionality or fails to meet regulatory specifications.

The apparatus provides precise control over applied force magnitude and duration, simulating compression scenarios encountered during storage, transportation, or operational use of electrical enclosures. This delivers scientifically validated data for product quality verification and ensures reliability of mechanical performance characteristics.
