Ergonomics is also related to the EU’s Design for All (DfA) policy, according to which products in the EU should be suitable for all users, including elderly or disabled people. For example, the Procurement Act requires public procurement to take the ’design for all’ principle into account.

Execution of steel and aluminum structures (SR 135)

The standardization group is responsible for the standardization of execution standards for steel and aluminum structures (SFS-EN 1090 series) and metallic tanks for the storage of liquids. The standardization group also follows the standardization of the international committee ISO/TC 167 (the counterpart committee to CEN/TC 135).

Load-bearing steel and aluminum structures:

CEN/TC 135: Standard SFS-EN 1090-1 is a harmonized standard (hEN) in accordance with the Construction Products Directive (Construction Products Regulation 305/2011/EU) that deals with provisions for conformity assessment of components which imply conformity to performance characteristics declared by the manufacturer of the components (CE-marking).

Metal tanks for the storage of liquids:

CEN/TC 265: The committee’s standards include; SFS-EN 12285 series, SFS-EN 14620 series and SFS-EN 14015 standard.

Water supply systems (SR 164)

The scope of the national standardization group is to participate in European standardization of water supply systems and sanitary appliances. Standardization of water supply systems covers installation and performance requirements as well as structural requirements for system components, including materials and water chemicals. Standardization of sanitary appliances covers the development of performance requirements and test methods, connection dimensions and product standards.

Standards support the design, calculation, implementation, commissioning and maintenance of water supply systems from the waterworks to the tap. The standardisation of water supply systems is influenced by the EU legislation on drinking water, which sets requirements for, among other things, water quality and materials used in water systems. The directive provides for a procedure for setting common health-based minimum requirements for construction materials in contact with water in the EU. The European Chemicals Agency (ECHA) has been tasked with compiling and regularly evaluating a health-based list of substances and materials permitted in the manufacture of construction products.

Wastewater technology (SR 165)

The scope of the national standardization group is the development of functional, performance and installation-related standards for wastewater drainage systems and their components. Product standards for technical areas that do not have their own technical committee (such as discharge pipes, stormwater and wastewater sewers, piping systems, separators) also fall within the scope of the group.

The standards support design, calculation, implementation, commissioning and maintenance from the point of origin of wastewater to wastewater treatment, also covering wastewater treatment plants.

About a quarter of the product standards in the scope of the national standardization group are subject to the Construction Products Regulation 305/2011 or the previous Construction Products Directive 89/106/EEC, i.e. harmonised product standards leading to CE marking.

Technical product documentation and tolerances (SR 290)

The standardization group SR 290 follows two subject areas: technical product documentation and geometric product specification (ISO GPS). All technical documents (machine drawings, construction drawings, process diagrams) should be prepared according to standardized rules.

The standardization of Technical Product Documentation (TPD) takes place in committee ISO/TC 10 and includes, among other things:

ISO standards for geometric product specifications are developed by committee ISO/TC 213. The ISO tolerance system is called the ISO GPS system (GPS = Geometric Product Specifications). Geometric product specifications include, among others:

In addition, standards for decision-making rules for measurement uncertainty are being developed by committee ISO/TC 213.

Model Based Definition (MBD) has been taken into account in the latest standards.

Participation in the standardization group SR 290 is free of charge based on the decision of the METSTA board, see the Participate page.

Maintenance and condition monitoring (SR 319)

The scope of the standardization group covers European and international standards for maintenance and condition monitoring. The key tasks of the standardization group are the preparation of Finnish statements and voting responses to European and international standard proposals, the preparation of the necessary Finnish-language maintenance and condition monitoring standards, and acting as a steering group for Finnish experts participating in European and international working groups.

Energy efficiency of buildings (SR 371)

The national standardization group coordinates horizontal standardization related to the energy efficiency of buildings on a project-by-project basis and brings together experts and authorities from different sectors when necessary. The basis for standardization is the Energy Performance of Buildings Directive (EPBD).

The construction sector is crucial for achieving the EU’s energy and environmental goals, and the Energy Performance of Buildings Directive implements the construction and renovation targets set in the European Commission’s Green Deal. The standards provide calculation models, tools, requirements and guidelines to support the assessment of the energy efficiency of buildings.

European standards aim to harmonise the calculation of energy use in the Member States, and the Energy Performance of Buildings Directive takes the standards into account in terms of reporting: the national energy efficiency calculation method must be described in accordance with the standards. This is the first step towards a common European calculation of energy use. The next step is to get the standards into a machine-readable format.

Ecodesign (SR 406)

Ecodesign standardization is based on the ERP Directive (2009/125/EU Energy Related Products Directive).

The aim is to produce publications that can:

Participation in the standardization group SR 406 is free of charge due to the decision of the METSTA board, see the Participate page.
