From Assumed Performance to Validated Outcomes​
RF and acoustic containment verification, diagnostic testing, and accreditation readiness—ensuring secure facilities perform as intended from construction through final certification.
​
Containment Verification In Practice
Sentinel Secure Build supports secure facility projects through a focused set of technical services that validate containment performance and support accreditation readiness. These services are integrated during construction and carried through final testing—providing measurable insight into RF shielding and acoustic containment performance at critical stages of delivery.
​
Integrated with Project Delivery
​Sentinel works alongside project teams to evaluate containment performance, identify deficiencies where present, and confirm that corrective actions achieve the intended results. This structured engagement supports a clear path from initial verification through final certification—without introducing unnecessary disruption to construction activities.
Sentinel supports containment planning by either developing the design and specifying shielding materials and installation methods, or by reviewing existing designs to confirm alignment with RF and acoustic performance requirements.
​
By resolving these conditions early, projects avoid downstream performance gaps, rework, and accreditation risk.
Containment performance cannot be assumed—it must be measured.
Sentinel conducts construction-phase RF and acoustic diagnostic testing to evaluate the enclosure as a complete system, identifying deficiencies that are otherwise undetectable through inspection alone.
​
This establishes a verified performance baseline prior to final accreditation.
Sentinel performs construction-phase acoustic testing to identify flanking paths and containment deficiencies while assemblies remain accessible, followed by formal certification testing to validate completed enclosure performance. Testing evaluates walls, doors, penetrations, and mechanical systems in line with ASTM E336 standards and provides defensible documentation aligned with accreditation requirements for both Sound Group 3 and 4.
Sentinel delivers defensible, accreditation-aligned documentation validating containment performance. Through final acoustic certification and RF containment verification, Sentinel produces clear, structured documentation of test methods, equipment, and measured performance—aligned with recognized practices (ASTM, IEEE 299) and formatted to support AO/CTTA accreditation review.
