Overview

EN 1096-4:2018 - “Glass in building - Coated glass - Part 4: Product standard” (CEN) specifies how to assess conformity and operate factory production control (FPC) for coated glass used in buildings. It implements the Assessment and Verification of Constancy of Performance (AVCP) requirements under the EU Construction Products Regulation (Regulation (EU) No 305/2011) and replaces the 2004 edition. The standard defines what manufacturers must document and declare (Declaration of Performance - DoP) for coated glass products.

Key topics and requirements

• Scope and purpose
  • Evaluation of conformity and the factory production control (FPC) system for coated glass.
  • Notes that other directives (e.g., Low Voltage Directive) may apply when products include wiring or electrical connections.
• Product description
  • Manufacturers must prepare and maintain a detailed product description covering coating type (on-line/off-line), deposition method, layer materials and order, glass substrates, and classification.
  • Definition of product family and rules for substitution of materials where equivalence is demonstrated.
• Assessment & AVCP
  • Procedures for type testing, test reports, and determination of a representative product-type.
  • Requirements for initial inspection, routine FPC, and continuous surveillance including sampling and corrective procedures.
  • Rules for handling modifications and pre-production prototypes.
• Declared characteristics
  • Spectrophotometric and energy characteristics (e.g., light transmittance, reflectance, solar factor (g)) must be declared in the DoP.
  • Emissivity tolerances updated - for declared normal emissivity < 0.10 the tolerance is reduced to +0.01.
  • Durability/conformity assessment and mechanical resistance (declared as characteristic bending strength of the glass substrate) must be included in the DoP.
• Annexes
  • Normative and informative annexes detail FPC procedures, factory tests, type testing, sampling, spectrophotometric measurements and the relationship to the EU CPR (Annex ZA).

Applications and users

EN 1096-4:2018 is intended for:

• Coated glass manufacturers needing to establish FPC and prepare a DoP.
• Test laboratories performing type tests and spectrophotometric/energy measurements.
• Certification bodies and notified bodies assessing AVCP compliance.
• Architects, façade engineers, specifiers and consultants requiring standardized performance data for coated glazing in building envelopes.
• Regulatory authorities and procurement teams verifying compliance with the CPR.

Related standards

• EN 1096-1, -2, -3, -5 (other parts of the coated glass series)
• EN 410 (luminous and solar characteristics)
• EN 673 (thermal transmittance / U-value)
• Annex ZA of EN 1096-4:2018 explains the link to Regulation (EU) No. 305/2011.

Keywords: EN 1096-4:2018, coated glass, glass in building, factory production control, AVCP, Declaration of Performance, emissivity, solar factor, spectrophotometric characteristics.

The layers may be listed either in full, i.e. chemical composition, or by a manufacturer's code. Product families shall be defined in terms of the above product description taking into account the criteria for demonstrating equivalence of coatings (see EN 1096-2:2012, Annex F and EN 1096-3:2012, Annex B).

Since they are not changed significantly by the coating process, they shall be used for coated glass. For glass substrates covered by European specifications, generally accepted values, declared values, or calculated values of the characteristics listed in Table 1 shall be used. If glass panes are used which are not covered by harmonized European Specifications (as defined in regulation EU305/2011), it shall be demonstrated that those glasses have a chemical composition and a mechanical stability over time equivalent to the requirements of the relevant standard listed.

If the information is not available, the normal emissivity shall be determined in accordance with EN 12898 and Annex C of this standard. b) The U-value shall be determined by calculation in accordance with EN 673, with the normal emissivity as defined above and the nominal thickness of the glass panes. 4.2.2.13 Energy conservation and heat retention - Radiation properties: Light transmittance and reflectance The light transmittance and light reflectance shall be determined either: a) in accordance with the following procedure: 1) The light transmittance and light reflectance of one sample of coated glass shall be determined in accordance with EN 410 and Annex C. The exact thicknesses of the glass shall be measured. 2) The light transmittance and the light reflectance of any other thickness shall be calculated according to EN 410. 3) The tool used to calculate the light transmittance and the light reflectance shall be validated.

on request of the manufacturer, the results of the assessment of samples of pre-production product may be included in a certificate or in test reports issued by the involved third party, as TT. The manufacturer should ensure the equivalence between pre-production samples and product made on the full production process. 6 Marking and/or labelling 6.1 General All voluntary marking and/or labelling shall comply with D.3. Care shall be taken to ensure that any voluntary marking and/or labelling does not cause confusion with respect to the mandatory requirements. 6.2 Product marking There is no requirement to permanently mark coated glass. However, if they are processed, e.g. thermally toughened, heat strengthened etc., then they have to comply with the appropriate product standard. SIST EN 1096-4:2018

Factory production control A.1 Factory Production Control Requirements A.1.1 General The factory production control system shall consist of procedures, regular inspections and tests and/or assessments and the use of the results to control (raw and other) incoming materials or components, equipment, the production process and the product.
