MECHANICAL ENGINEERING - GENERAL
In 2024, CEN and CENELEC technical bodies working on the machinery sector will start working on the first harmonized standards in support of the Machinery Regulation (EU) 2023/1230.
In 2024, CLC/TC 44X ‘Safety of machinery: electrotechnical aspects’ will work on a brand-new harmonized standard in support of the Machinery Regulation (EU) 2023/1230 to address the new requirements on protection against corruption.
In 2024, CEN/TC 211 will work together with ISO/TC 43/SC 1 to enhance standards related to sound power level determination and overall usability. Among them:
- The revision of EN ISO 3744 ‘Acoustics - Determination of sound power levels of noise sources using sound pressure - Engineering methods for an essentially free field over a reflecting plane (ISO/DIS 3744:2023)’. This is a crucial standard used by manufacturers and test laboratories to determine sound power level. The primary objective of this revision is to simplify the standard and enhance its user-friendliness.
- A new standard to improve the readability and applicability of EN ISO 3744. As part of this effort, the current annex addressing uncertainties in EN ISO 3744 will be shifted to EN ISO 5114-1 ‘Determination of uncertainties associated with sound emission measures - Part 1: Sound power levels determined from sound pressure measurements’.
LABORATORY, OPTICAL AND PRECISION EQUIPMENT (EXCL. GLASSES)
For 2024, CEN/TC 176 'Thermal Energy Meters' has outlined a comprehensive work programme on several key areas. These initiatives intend to bring about enhancements and amendments to the harmonized standards series, primarily EN 1434, in alignment with Directive 2014/32/EU on Measuring Instruments. The specific areas of emphasis include durability, sensitive measuring, influence of flow profiles, conductive pastes for pockets, fast response metering, and sustainability aspects. Additionally, the TC will focus on the revision of two technical reports:
- CEN/TR 13582 ‘Installation of thermal energy meters - Guidelines for the selection, installation and operation of thermal energy meters’;
- CEN/TR 16911 ‘Heat meters - Recommendations for circulation water in industrial and district heating systems and their operation’
In 2024, CEN/TC 318 'Hydrometry' expects to develop a new European Standard: 'Hydrometry - Measurement of precipitation intensity - Metrological requirements and test methods for non-catching type rain gauges'. This new standard aims to address the measurement of precipitation intensity using rain gauges that do not involve the catching of precipitation.
CEN/TC 332 'Laboratory Equipment' closely collaborates with its international counterpart ISO/TC 48 to adopt European Standards (ENs) for laboratory equipment. These ENs closely align in structure and content with ISO standards, making the transformation between the two systems both reasonable and promising. Furthermore, in 2024, CEN/TC 332 will work on the following standards:
- EN 17242 'Recirculatory Filtration Fume Cupboards';
- EN 16589-2 'Laboratory Local Exhaust Devices - Part 2: Commissioning and On-Site Testing of Articulated Extraction Arms';
- Revision of EN 12469 'Biotechnology - Performance Criteria for Microbiological Safety Cabinets'. The aim of this revision is to create a standard series that incorporates the latest developments and aligns with the current state of the art in biotechnology.
AGRICULTURE MACHINERY AND MOTOR-OPERATED ELECTRIC TOOLS
The work of CEN/TC 144 'Tractors and machinery for agriculture and forestry' focuses on machine safety and operator protection, taking into account the protection of the environment and technological innovations. These documents play an important part in decreasing the risk of accidents for farmers and foresters and in reducing the use of pesticides. The intended main users for these standards are not only farmers, foresters, and manufacturers, but also public authorities in charge of prevention at work and inspection of machines, and research and testing organizations.
In 2024, CEN/TC 144 will continue developing standards on the automation of machines and tractors, as the dedicated market is growing rapidly. In this context, CEN/TC 144, in cooperation with ISO, plans to finalize the EN ISO series 18497 'Agricultural machinery and tractors - Safety of partially automated, semi-autonomous and autonomous machinery' in support of the Machinery Directive (2006/42/EC). The series, which consists of four parts, will establish the general design principles to cover the combination of the different functions of machines and tractors, the location of the operator and the types of interaction of these functions.
Another TC involved in this sector is CLC/TC 116 'Safety and Environmental Aspects of Motor-Operated Electric Tools'. In 2024, CLC/TC 116 will work on new European Standards aimed at enhancing safety and technological integration in the realm of motor-operated electric tools and machinery for lawn and garden.
In the pipeline are standards covering an array of hand-held and transportable tools, together with lawn and garden machinery. For instance, CLC/TC 116 will continue developing different parts of the EN IEC 62841-2-X, EN IEC 62841-3-X and EN IEC 62841-4-X series.
PRESSURE EQUIPMENT
Pressure equipment encompasses diverse devices, each characterized by unique complexities, materials, operating conditions, manufacturing processes, and control technologies. At the heart of safety regulations in the European Union, the Pressure Equipment Directive (Directive 2014/68/EU) governs pressure equipment in a broad spectrum of industries. A recent Standardization Request in support of Directive (EU) 2014/68 and Directive 2014/29/EU involves developing and revising a comprehensive set of European standards and standardization deliverables, totalling 234 standards for PED and 9 standards for SPVD; and introducing 18 new European standards covering PED aspect crucial for aligning with Union legislation and policies.
Moreover, with hydrogen playing an increasingly pivotal role in various industries, several technical committees within CEN are in the process of revising existing standards under the framework of the Pressure Equipment Directive (2014/68/EU) to cater to the emerging demand for hydrogen deployment technologies. Their scope also extends to meet the aviation sector's current needs, in line with Europe's 2050 climate objectives.
To this end, significant efforts are already underway in CEN/TC 54 ‘Unfired Pressure Vessels’ . This committee aims to specify the requirements for unfired pressure vessels and their components designed for hydrogen applications, in addition to the general requirements for unfired pressure vessels.
A significant achievement for CEN/TC 54 will be to finalize the EN 286 series, which addresses 'Simple unfired pressure vessels designed to contain air or nitrogen’, in support of the SPVD (2014/29/EU).
Similarly, CEN/TC 267 ‘Metallic Industrial Piping’ will define the requirements for materials, design, fabrication, inspection, and testing of industrial piping as defined in EN 13480-1:2017. It will cover individual spools or piping systems, including supports, designed in accordance with EN 13480-3:2017 and EN 13480-6:2017 (if applicable), and fabricated and installed following EN 13480-4:2017.
Furthermore, CEN/TC 121 ‘Welding and allied processes’, following the Vienna Agreement, will conclude work on several crucial standards:
- EN ISO 15613: 'Specification and Qualification of Welding Procedures for Metallic Materials - Qualification Based on Pre-Production Welding Test (ISO/DIS 15613:2022)';
- EN ISO 15611: ‘Specification and Qualification of Welding Procedures for Metallic Materials – Qualification Based on Previous Welding Experience (ISO/FDIS 15611:2023)';
- EN ISO 15614-11: 'Specification and Qualification of Welding Procedures for Metallic Materials - Welding Procedure Test - Part 11: Electron and Laser Beam Welding (ISO/DIS 15614-11:2022)'.
CEN/TC 121 will also initiate work on EN ISO 15614-14, which deals with 'Specification and Qualification of Welding Procedures for Metallic Materials - Welding Procedure Test - Part 14: Laser-Arc Hybrid Welding of Steels, Nickel, and Nickel Alloys.' These efforts are pivotal for ensuring the highest safety and performance standards in pressure equipment and welding in Europe.
