This document provides product category rules (PCR) for Type III environmental declarations for curtain walling as defined in EN 13830:2015+A1:2020, excluding openable infills. Openable infills are addressed in EN 17213:2020.
This document complements the core rules for the product category of construction products as defined in EN 15804:2012+A2:2019. This document complements EN 15804:2012+A2:2019 and does not replace it.
NOTE   The assessment of social and economic performances at product level is not covered by this document.
The core PCR:
-   defines the parameters to be declared and the way in which they are collated and reported;
-   describes which stages of a product’s life cycle are considered in the EPD and which processes are to be included in the life cycle stages;
-   defines rules for the development of scenarios;
-   includes the rules for calculating the life cycle inventory and the life cycle impact assessment underlying the EPD, including the specification of the data quality to be applied;
-   includes the rules for reporting the predetermined, environmental and health information that is not covered by life cycle assessment (LCA) for the product, construction process(es) and construction service(s), as relevant;
-   defines the conditions under which construction products can be compared based on the information provided by EPD.
For the EPD of construction services the same rules and requirements apply as for the EPD of construction products.

This document provides a test method for determining the bearing capacity (pull out force) of a connection consisting of a screw in a screw thread channel, which cannot be calculated in accordance with current codes or conventional calculations. This document can be applied to screw thread channels used in several products, including doors, windows and curtain walling.
This document is applicable to screw thread channels made out of metal, as well as metal screws.
The pull out forces of such connections can already be assessed indirectly with another test method e.g. wind load resistance for doors/windows according to EN 12211 or curtain walling kits according to EN 12179. Additional information with respect to the mechanical performance of connections and direct applications can be determined with the test method described in this document.
The bearing capacity of non-metallic components under the combination of high temperature and load is not considered in the standard. Additional verifications are performed depending on the type of the non-metallic material used.

This document specifies test methods for the determination of bearing capacity (ultimate limit state and serviceability limit state), of connections between curtain walling framing members which cannot be calculated in accordance with current codes or conventional calculations based upon the strength of the materials.
Mechanical performances of the curtain walling connections are already assessed in accordance with the provisions described in EN 13830. Additional information with respect to mechanical performance of the connections and direct applications can be determined with this document (see Annex C).

This European Standard specifies requirements of curtain walling kit intended to be used as a building envelope to provide weather resistance, safety in use and energy economy and heat retention and provides test/assessments/calculation methods and compliance criteria of the related performances.

This European Standard does not include:
—   “Patent glazing” (glazed sloping roofs) kits;
—   Roof glazing constructions;
—   Façades made of precast concrete panels as part of the wall (see EN 14992).

This document specifies test methods for the determination of the bearing capacity (ultimate limit state and serviceability limit state) of infill support which cannot be calculated in accordance with current codes or conventional calculations based upon the strength of the materials or to compare the calculation when necessary.
Three different types of infill (glass) supports are dealt in this standard:
- The cantilever infill (glass) supports, see Figure 1 (a);
- The cruciform infill (glass) supports only fixed to the mullion, see Figure 1 (b);
- Corner infill (glass) supports only fixed to the mullion, see Figure 1 (c).
The test method is intended for the assessment of cantilever infill (glass) supports that have not been tested according to EN 16758 (see Figure 9). The results of the test method can only be interpreted when incorporated with the results from a test in accordance with EN 16758.
It is essential that cruciform and corner infill (glass) supports only fixed to the mullion are tested in accordance with this standard.
The infill (glass) supports connected to the mullion and the transom together are considered as a part of sheared connection and are covered by EN 16758.
Where the mechanical performances of the infill (glass) support is already assessed in accordance with the provisions described in EN 13830, additional information with respect to mechanical performance of the infill (glass) support and direct applications can be determined with this standard.

This European Standard defines performance requirements of curtain walling (excluding ‘glass in building’ which is classified under EN 12600) under soft body impact load criteria specified herein and tested in accordance with EN 13049.
Its criteria is targeted to safety in use and integrity of curtain wall in the event of sudden impact forces on the curtain wall surfaces. Compliance with the performance requirement is determined by the laboratory test.
