EN 13141-7:2021+A1:2025 outlines laboratory test methods and requirements for assessing the performance of ducted mechanical supply and exhaust ventilation units, including those with heat recovery functions. These bidirectional ventilation units are essential in modern residential and commercial buildings, contributing significantly to indoor air quality, thermal comfort, and energy efficiency.
The standard covers:
Aerodynamic, thermal, acoustic, and electrical performance characteristics
Units containing fans, air filters, air-to-air heat exchangers or heat pumps, and integrated controls
Various system configurations and assembly arrangements, provided they are designed to be used together
Key areas tested and certified include leakage (internal/external), airflow rates (max, min, reference), pressure, energy consumption, heat recovery efficiency, filtering performance, and acoustic output. Notably, this standard is applicable only to ducted units and excludes those with water-based heating/cooling or combustion-driven heat pumps.
Who should comply:
Ventilation system manufacturers and component suppliers
Residential and commercial builders
HVAC engineers and specifiers
Practical implications: Integrating systems tested to EN 13141-7 guarantees reliable air exchange, effective recovery of expended heat, and energy-efficient operation, ultimately improving indoor air quality and lowering energy costs for end users.
Key highlights:
Defines thorough testing for airflow, pressure, and leakage rates
Establishes methodologies for real-world, representative heat recovery assessment
Mandates acoustic testing to minimize noise pollution inside buildings

IEC TR 62786-100:2026 - Grid Connection Standard Mapping for Distributed Energy Resources
Distributed energy resources connection with the grid - Part 100: Generating plants and units grid connection standard mapping
IEC TR 62786-100:2026 is a comprehensive guidance document for drafting international publications that involve the connection of distributed energy resources (DER) to electrical grids. This includes solar, wind, and other decentralized power systems, crucial as buildings increasingly generate, store, and manage their own energy.
The technical report helps:
Harmonize requirements for DER grid connection across different standards and regulatory contexts
Avoid overlaps and redundancies by listing significant related IEC, national, and regional documents
Guide technical committees in drafting new DER connection standards
It categorizes publications into four areas:
Basic publications: General terms, definitions, power quality, and EMC guidelines
System publications: System-level requirements at the point of grid connection
Testing publications: Testing provisions for grid interfacing equipment
Product publications: Requirements for specific DER products (inverters, batteries, etc.)
Who should comply:
DER manufacturers and integrators
Electrical engineers and utilities
Regulatory bodies and standards developers
Practical implications: Implementing IEC TR 62786-100 ensures new DER installations are compliant, interoperable, and ready for increasingly complex smart grid environments. For product developers, referencing the right set of harmonized standards minimizes costly redesigns or compliance failures, while utilities benefit from more reliable grid integration.
Key highlights:
Provides a clear mapping of all DER-related grid connection standards
Promotes international alignment, enhancing global product acceptance
Reduces compliance risk by listing key requirements and guidance

ISO 15957:2026 - Test Dusts for Air Cleaning Equipment Evaluation
Test dusts for evaluating air cleaning equipment
ISO 15957:2026 specifies the properties and classifications of load test dusts used in laboratories to evaluate the dust-handling capacity of HVAC air filters and air cleaning devices. Testing air cleaning systems using standardized dusts ensures objective performance comparisons and supports selection and certification of suitable units for diverse building environments.
The document covers:
Physical and chemical properties for various designated test dusts (L1 through L5)
Detailed particle size distributions and analysis procedures
Application methods in the evaluation of air cleaning and dust filtration devices
This standard does not address test dust for filter efficiency performance, focusing instead on filter loading and endurance characteristics.
Who should comply:
Filter and air cleaner manufacturers
Building laboratories and test facilities
Product certifiers and regulatory agencies
Practical implications: By applying ISO 15957 test dusts, manufacturers and facility managers can select or specify air cleaning systems with proven real-world dust-handling capabilities, reducing maintenance, improving air quality, and supporting lifecycle cost optimization.
Key highlights:
Standardizes five types of test dust for robust air filter evaluation
Ensures repeatable, comparable results across laboratories
Supports filter design and facility management decisions impacting health and productivity

SIST EN 12480:2026 - Rotary Displacement Gas Meters
Gas meters - Rotary displacement gas meters
SIST EN 12480:2026 defines the construction, performance, and testing requirements for rotary displacement gas meters (RD meters), used for precise measurement of fuel gas volumes. The standard covers meters for the primary gas families at working pressures up to 20 bar and in wide-ranging environmental conditions.
The requirements address:
Operating range for flow, pressure, and temperature
Metrological performance (accuracy, repeatability, pressure loss)
Resistance to corrosion, leakage, vibration, and electromagnetic disturbance
Design, material selection, and robust marking for identification and maintenance
