International standards in the construction industry-Part 2
ICS 91.100.60 - THERMAL AND SOUND INSULATING MATERIALS 27.160 - SOLAR ENERGY ENGINEERING
We have already mentioned the importance of compliance with the international system of standards when operating on the international market. Since the sphere of construction is quite extensive, the number of standards and parameters that they regulate is also significant. Exactly international standards are responsible for the safety and quality of the final result that a company wants to achieve. Today we will introduce the second part of the most demanded documents in the field of construction.
Thermal insulation products for buildings - Factory made calcium silicate (CS) products - Specification
A wide variety of materials are used in the construction process. To regulate the quality of production, special standards are created. One such standard is SIST EN 16977: 2020. This draft European Standard specifies the requirements for factory made calcium silicate products with or without lamination or coating which are used for the thermal insulation of buildings. Calcium silicate products have also the capability to regulate air moisture in building rooms, which means to absorb moisture from the air and opposite to give the moisture back to the room due to the capillarity of the product. Calcium silicate insulation material comprising hydrated calcium silicate, normally reinforced by incorporated fibres. The main crystal phases are Xonotlite, Tobermorite with or without Wollastonite. The products are manufactured in the form of boards, segments and prefabricated ware. This draft European Standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling. This draft European Standard does not specify the required level or class of a given property that shall be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application can be found in regulations and invitations to tender. This draft European Standard does not cover aerated concrete, autoclaved aerated concrete, mineral foam insulating products and sand-lime bricks as well as in situ insulation products and products intended to be used for the insulation of the building equipment and industrial installations. Since this standard is specialized, we recommend that you contact our team to clarify the details and parameters of the document's compliance with your business.
Thermal insulation products for buildings - Factory-made vacuum insulation panels (VIP) - Specification

Solar collectors - General requirements
Solar energy is one of the most popular alternative energy sources in the 21st century. The more actively this industry develops, the more Regulatory Documents appear in the world. One of the main international standards SIST EN 12975: 2019. This document is applicable to all types of fluid heating solar collectors. This European Standard specifies performance requirements for fluid heating solar collectors with respect to durability, reliability, safety and thermal performance. This European Standard includes provisions for the assessment and verification of constancy of performance to these requirements. This document deals with the collector module and not with assemblies. This document is not applicable to those devices in which a thermal storage unit is an integral part to such an extent that the collection process cannot be separated from the storage process for making the collector thermal performance measurements. If your field of activity is solar energy, we recommend that you familiarize yourself with the details of this standard on our website.
Thermal insulation products for building - Factory made vegetal fibres based products (VFBP)
Specific devices for the construction industry are also regulated by standards, since parts for production are responsible for the quality of the entire process. For instance SIST EN 17139:2018 regulates products that are manufactured in form of rolls, felts, slabs or boards. Products covered by this standard may also be used for acoustic applications.The standard also covers multi-layered boards and slabs and composites insulation boards and slabs. Products covered by this standard are also used in prefabricated insulating systems and composites panels. The structural performance of systems incorporating these products is not covered by this standard. This European Standard applies to any thermal insulation products made of at least 70% of vegetal fibres per mass with or without the addition of bonding agents or bonding fibres and/or additives and which don’t fall within the scope of the EN 13171. It does not replace the existing procedures for the determination of the declared properties of products already covered by an existing harmonized standard.” Part 1 of this European Standard describes the products characteristics and includes procedures for testing, marking and labelling and the rules for the evaluation of conformity. This standard does not specify the required level of all properties to be achieved by a product to demonstrate fitness for purpose in a particular application. The required levels are to be found in regulations or non-conflicting standards. Products with a declared thermal conductivity at 10°C, greater than 0.06 W/(m.K) or a declared thermal resistance lower than 0.25 m2/k/W are not covered by this standard. This European Standard does not cover in-situ applied insulation and products intended to be used in the insulation of building equipment and industrial installations. If you have any questions about whether it is possible to use this standard in your field of activity, we recommend that you familiarize yourself in more detail with the detailed description at the link.
Thermal insulation products for buildings - In-situ formed loose fill cellulose (LFCI) products - Part 1: Specification for the products before installation
Construction specifications must be strictly observed in accordance with international regulations. Product quality can significantly increase demand and, as a result, the profitability of activities. One of the documents that can help with this is EN 15101-1: 2013 + A1: 2019. This European Standard specifies requirements for loose-fill cellulose insulation (LFCI) products for the thermal and/or sound insulation of buildings when installed into walls, floors, galleries, roofs and ceilings. This European Standard is a specification for the loose-fill cellulose insulation (LFCI) products before installation. This European Standard describes the product characteristics and includes procedures for testing, marking and labelling and the rules for evaluation of conformity. Products covered by this European Standard may also be used in prefabricated thermal insulation systems and composite panels; the structural performance of systems incorporating these products is not covered. Products with a declared thermal conductivity at 10 °C greater than 0,060 W/(m K) or a declared thermal resistance lower than 0,25 m2 K/W are not covered by this European Standard. This European Standard does not specify the required level of all properties to be achieved by a product to demonstrate fitness for purpose in a particular application. The required levels are to be found in local regulations or non-conflicting standards. This European Standard does not cover factory made cellulose products placed on the market as bats, mats or boards intended to be used for the insulation of buildings or loose-fill cellulose products for the insulation of building equipment and industrial installations. That is why it is better to entrust the selection of international standards to a professional in order to minimize the risk of an error.
Thermal insulation products of buildings - In-situ formed products from loose-fill expanded polystyrene (EPS) beads and bonded expanded polystyrene beads - Part 1: Specification for the bonded and loose-fill products before installation
Installation of equipment is a laborious and complex process, which can only be carried out with high quality in the case of strict compliance with standards. To prevent negative consequences, international standards are created that describe details and step-by-step recommendations, one of them is EN 16809-1: 2019. This document specifies the requirements for products of loose-filled expanded polystyrene (EPS) beads and bonded expanded polystyrene beads for in-situ installation in masonry cavity walls and frame constructions. This document is a specification for the insulation products before installation. It describes the product characteristics and includes procedures for testing, marking and labelling. This document does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application are to be found in regulations or non-conflicting standards. To avoid water penetration in masonry walls special tests adjusted to local climate might be needed. This document does not cover factory made expanded polystyrene (EPS) insulation products or factory made or in-situ products intended to be used for the insulation of building equipment and industrial installations. Products with a declared thermal resistance lower than 0,25 m2·K/W or a declared thermal conductivity greater than 0,060 W/(m·K) at 10 °C are not covered by this document.

One of the most popular documents EN 12976-2: 2019. This document specifies test methods for validating the requirements for Factory Made Thermal Solar Heating Systems as specified in EN 12976-1. The document also includes two test methods for thermal performance characterization by means of whole system testing. Globally, this standard can be applied to any business that comes into contact with salt energy in the process. For details on the application and purchase of the standard, follow the link.
Thermal insulating products for building applications - Determination of long-term water absorption by diffusion (ISO 16536:2019)
The construction and testing and launch process is strictly regulated not only locally but also internationally. The scale of the construction industry market is expanding and standards have been created to structure it. One of them is EN ISO 16536: 2019. This document specifies the equipment and procedures for determining the long-term water absorption of test specimens by diffusion. It is applicable to thermal insulating products. It is intended to simulate the water absorption of products subjected to high relative humidities, approximating to 100 %, on both sides and subjected to a water vapour pressure gradient for a long period of time e.g. inverted roof or unprotected ground insulation. The test is not applicable for all types of thermal insulating products. The relevant product standard should state for which of its products, if any, this test is applicable. We recommend that you adhere to international norms and rules for the progressive development of your company, and our team is always ready to help you.
Energy performance of buildings -- Schedule and condition of building, zone and space usage for energy calculation
A correctly formulated economic and financial aspect of construction can minimize unnecessary costs and significantly increase productivity and, as a result, the amount of profit. ISO 18523-2:2018 specifies the formats to present the schedule and conditions of zone and space usage (referred to as input data of energy calculations) for residential buildings. The schedule and conditions include schedules of occupancy, operation of technical building systems, ventilation rates, hot water usage, usage of appliances and internal heat gains due to occupancy, lighting and appliances. The schedule and conditions for lighting are applicable to fixed installed lighting fixtures. ISO 18523-2:2018 also gives categories of residential building, zone and space according to differentiating schedule and condition. For residential buildings or its housing units which contain any category of space or zone of non-residential buildings, ISO 18523‑1 applies. Depending on necessary minuteness of the energy calculation, different levels of schedule and condition from the view point of time and space averaging are specified. The values and categories for the schedule and condition are included informatively. The schedule and condition in this document is basically different from assumptions in order to determine the size of technical building systems in the process of design, where possible largest or smallest values are assumed. Instead, most usual and average values, which are assumed for the building energy calculation, are dealt with in this document.
