• Specifies functions, performance, interfaces, and environmental adaptability for real-time intelligent video analysis.
• Encompasses both live monitoring and forensic analysis contexts, making it applicable across public infrastructure, industrial facilities, transportation hubs, and smart cities.
• Clearly defines procedures for assessing core capabilities (object classification, tracking, movement analysis) and complex scenarios (loitering detection, perimeter intrusion, person-down detection, fire or explosion identification, suspicious behavior, and more, as detailed in Annexes H & I).
• Outlines XML-based data schema for standardized test and evaluation reporting.

Who Needs to Comply:

• Security technology vendors
• Systems integrators and installers of surveillance systems
• Critical infrastructure operators (utilities, energy, transportation, etc.)
• Compliance and risk management professionals

Practical Implementation:

• Detailed grading and performance certification frameworks support transparent tendering and procurement.
• Extensive test sets and environmental scenarios help organizations tailor system performance to real-world risk profiles.
• Promotes interoperability and benchmarking among VCA systems from different manufacturers.

Notable Changes:

• Expands upon previous versions by introducing new scenario-based capabilities and updated grading methodologies, integrating “degrees of difficulty” for more precise grading.
• Enhances environmental adaptability testing, including vibration, obscuration, and low-light scenarios.
• Offers expanded guidance for certification houses and user organizations.

Key highlights:

• Comprehensive testing of object detection and classification in real time
• Scenario-based evaluation covering loitering, abandoned objects, and threat identification
• Standardized grading to support compliance, certification, and procurement

EN ISO 8528-13:2026 – Safety Requirements for Reciprocating Engine-Driven Generating Sets

Reciprocating internal combustion engine driven alternating current generating sets – Part 13: Safety (ISO 8528-13:2026)

EN ISO 8528-13:2026 is the definitive standard for the safety requirements of reciprocating internal combustion (RIC) engine-driven generating sets. These systems are vital in delivering dependable power for land and marine applications, including industrial plants, distributed generation, healthcare, and critical infrastructure facilities.

Scope and Requirements:

• Covers safety requirements for RIC engine-driven generating sets up to 1,000 V AC or 1,500 V DC and, in specified cases, up to 36 kV for AC.
• Applies to both stationary and mobile generator sets for land and marine environments (excluding seagoing vessels, mobile offshore units, road vehicles, and aircraft propulsion).
• Specifies design, risk reduction, and verification measures for:
  • Starting and stopping systems (including emergency functions)
  • Control and monitoring devices, including accessibility and labeling
  • Guarding against mechanical and electrical hazards
  • Emissions, fire protection, and cooling systems
  • Electrical equipment integration and operator interfaces
• Establishes requirements in alignment with the principles of ISO 12100 (general risk assessment and risk reduction).

Who Needs to Comply:

• Generator manufacturers
• Installers and system integrators
• Infrastructure and facility managers
• Industrial, marine, and emergency backup power operators

Practical Implementation:

• Emphasizes documentation, marking, and operator instruction, supporting both procurement and operational training.
• Comprehensive verification procedures (inspection, measurement, testing) to ensure conformity with functional safety and machine guarding requirements.
• Addresses noise, exhaust, fire, electrical, and mechanical safety to minimize risk across the generator lifecycle.

Notable Changes:

• Updated normative references and terminology for consistency with the latest ISO and IEC standards.
• Enhanced requirements for high-voltage equipment and emergency stop devices.
• New annexes outline specific hazards and guidance for low-power and layperson-use cases.

Key highlights:

• Rigorous design and verification of emergency stops, monitoring, and warning systems
• Safety-focused integration across mechanical, electrical, and environmental domains
• Practical risk reduction measures for industrial, domestic, and marine generators
