Application and Configuration Review

Define the required sand or dust exposure before selecting the chamber. Review specimen loading, particle specification, airflow, temperature and humidity conditions, and monitoring against the approved test plan.

Details to Define in the RFQ

Specimen dimensions, mass, fixture arrangement, and required loading access.
Particle type and distribution, concentration or dosage, airflow, and exposure duration.
Any specimen pressure differential, operating state, and monitoring requirements.
Dust handling, site utilities, maintenance, and acceptance criteria.

Standards and Method Review

IEC 60529: degrees of protection provided by enclosures (IP Code).
IEC 60068-2-68: environmental testing, Test L: dust and sand.

Confirm the applicable edition, test procedure, specimen category, and chamber capability. Provide any additional project standards for review.
