Testing Items

Public security technology assessment programs typically combine the following categories of testing items, selected according to product function and applicable standards:

• Electrical safety: dielectric strength, insulation resistance, leakage current, protective grounding continuity, and protection against electric shock.
• Functional performance: detection sensitivity and coverage, false alarm and missed detection rates, walk-through and transit detection uniformity, image resolution, signal-to-noise ratio, dynamic range, and intelligent analysis accuracy.
• Environmental adaptability: high and low temperature operation and storage, damp heat cyclic exposure, vibration, mechanical shock, and ingress protection against dust and water.
• Electromagnetic compatibility: radiated and conducted emissions, electrostatic discharge immunity, radiated radio-frequency immunity, electrical fast transient bursts, surge withstand, and power frequency magnetic field immunity.
• Radiation safety for X-ray equipment: dose per inspection, air kerma rates, radiation leakage outside the inspected volume, and interlock functionality verification.
• Reliability and durability: mean time between failures demonstration, continuous duty cycle endurance, mechanical lifespan of locks and gates, and repeated transit testing for screening portals.
• Cybersecurity and data protection: secure boot and firmware integrity, encrypted transmission, access authentication strength, audit logging, resistance to common network attacks, and personal information protection compliance.
• Material and structural verification: flame retardancy, corrosion resistance, impact resistance, and stability of enclosures and mounting hardware.

Testing Methods

Climatic and mechanical testing is performed in environmental chambers and on electrodynamic shakers in accordance with the IEC 60068-2 series of environmental test methods, which define procedures for dry heat, cold, damp heat cycles, sinusoidal and random vibration, and shock. Results confirm that equipment maintains specified performance after exposure to transportation and operational stresses typical of outdoor and industrial deployment.

Electromagnetic compatibility evaluation is conducted in semi-anechoic chambers and shielded rooms using methods aligned with the IEC 61000-4 immunity series and applicable CISPR emission limits. Test severity levels are selected to match the intended installation environment, with higher levels applied to equipment destined for airports, mass transit, and industrial sites.

Detection performance verification uses calibrated test objects, including standardized metallic test pieces, surrogate explosive and narcotic samples, and resolution test phantoms for X-ray imaging systems. Sensitivity maps are generated across the entire detection volume to quantify uniformity, while probability of detection and false alarm rates are statistically derived from repeated trials under controlled conditions.

Radiation safety measurements employ calibrated dosimetry instrumentation to verify that dose per inspection and leakage radiation remain within the strict limits defined by applicable national standards and international radiation protection guidance. Interlocks, warning indicators, and emergency stop functions are validated under fault conditions.

Cybersecurity assessment combines protocol conformance testing, penetration testing, and code and configuration review, referencing frameworks such as ISO/IEC 27001 and national video surveillance cybersecurity standards. Audio and video data streams are examined for encryption strength, authentication mechanisms, and resistance to replay, tampering, and unauthorized access attempts.

Image quality evaluation for surveillance products uses standard test charts and controlled illumination to measure resolution, color fidelity, gray-scale response, wide dynamic range performance, and low-illumination behavior, complemented by bandwidth and latency measurements under representative network conditions.

FAQ

What standards govern public security technology assessment?

Evaluation programs are built on national standards such as the GB and GA series covering surveillance, alarm, and screening equipment, together with international frameworks from ISO, IEC, EN, UL, and ASTM. The specific standard set applied to a product depends on its function, deployment environment, and the regulatory requirements of the target market. Accredited third-party laboratories can help map a product to the most efficient combination of standards for the intended certification pathway.

Is third-party testing mandatory for public security products?

Requirements vary by product category and jurisdiction. Certain categories, particularly security screening equipment with radiation sources and products procured for government security projects, require testing by accredited third-party laboratories before deployment. In other cases, voluntary certification provides a competitive advantage in tenders and demonstrates independent verification of performance claims.

How many samples are required for a typical assessment?

Sample quantities depend on the scope of testing. A comprehensive program covering electrical safety, environmental, electromagnetic compatibility, and functional performance typically requires several units so that destructive or endurance tests do not contaminate functional results. Laboratories provide a documented sample list and test plan before commencement, and representative production units are preferred over hand-built prototypes.

What is the typical timeline for completing an assessment?

Standard testing programs for a single product category generally range from several weeks to a few months, depending on sample readiness, the extent of environmental and reliability sequences, and whether remediation and retesting are needed after nonconformities. Cybersecurity evaluations and radiation safety measurements may extend the schedule due to specialized instrumentation and detailed analysis requirements.

Can national and international certifications be combined in one program?

Yes. Many test items, such as environmental adaptability and electromagnetic compatibility, overlap substantially between national standards and international IEC, EN, and UL frameworks. A well-structured test plan can leverage this overlap to generate data packages supporting multiple certification targets simultaneously, reducing duplicated effort and accelerating global market entry.

How is cybersecurity addressed in modern assessments?

Contemporary evaluation programs integrate security-by-design verification, including firmware integrity checks, encrypted communication validation, authentication strength analysis, and penetration testing aligned with recognized information security management principles. These activities respond to the growing regulatory focus on protecting personal data and preventing network-borne attacks against connected security infrastructure.
