Overview

EN 572-9:2004 - "Glass in building - Basic soda lime silicate glass products - Part 9: Evaluation of conformity/Product standard" is the CEN standard that specifies how manufacturers demonstrate conformity of basic soda‑lime silicate glass for use in buildings. It sets out requirements for initial type testing, factory production control (FPC), inspection, marking/labelling, and the documentation needed to support performance claims. EN 572-9:2004 is Part 9 of the EN 572 series and supports regulatory requirements under the EU Construction Products Directive (see Annex ZA for CE marking and Declaration of Conformity).

Key topics and requirements

• Scope and product definition: Applies to basic soda‑lime silicate glass products as defined in EN 572‑1 and the other EN 572 parts (float, patterned, wired, etc.).
• Initial type testing (ITT): Demonstration of performance of essential characteristics and durability via tests or recognized calculation methods; results recorded in a test report.
• Factory production control (FPC): Organisation, control system, inspection/testing tables and continuous surveillance requirements to ensure production consistency (see Annex A normative).
• Essential characteristics covered:
  • Mechanical and thermal properties (density, Young’s modulus, bending strength, resistance to thermal shock)
  • Optical properties (light and solar transmittance, refractive index)
  • Safety-related characteristics (fire resistance/reaction to fire, impact/shatter behaviour, burglar and explosion resistance, bullet resistance, pendulum impact) referenced to specific EN test standards.
• Dangerous substances: Requirements to address regulated substances when relevant.
• Marking and labelling: Product marking, identification of declared characteristics, and guidance for a “characteristics/performance identification paper”.
• Conformity systems & surveillance: Options for initial inspection, continuous assessment of FPC, and voluntary third‑party involvement (Annex B).

Practical applications and users

Who uses EN 572-9:2004:

• Glass manufacturers - to establish FPC, ITT and prepare CE marking and Declarations of Conformity.
• Testing laboratories & notified bodies - to perform and certify initial and periodic tests.
• Architects, specifiers and façade engineers - to evaluate declared glass performance for building safety, energy and acoustic requirements.
• Regulators and certifiers - to verify compliance with construction product regulations. Practical uses include supporting product specifications, CE marking, tender documentation, and proving safety (fire, impact, burglar/explosion resistance) and thermal/optical performance for building glazing.

Related standards

• EN 572‑1 to EN 572‑8 (product definitions and types)
• EN 410, EN 673 (optical and thermal properties/U‑value)
• EN 12600, EN 1063, EN 356, EN 13541 (impact, bullet, burglar, explosion)
• EN 13501‑1/2/5 (reaction and resistance to fire) These referenced standards define the test methods and classifications used to demonstrate conformity under EN 572‑9:2004.

Instead of performing any actual testing, initial type testing may make use of: – generally accepted and/or conventional and/or standardised values, in the Clause 2 referenced standards, or in publications that are referred to in these standards; – standardised calculation methods and recognised calculation methods in
Clause 2 referenced standards, or in publications that are referred to in these standards; – test report(s) on the basis of 5.2.1.2 when made available except for the characteristics listed in 5.2.2. – where components are used whose characteristics have already been determined, by the component manufacturer, on the basis of conformity with other product standards, these characteristics need not be reassessed providing they remain unchanged by the manufacturing process; – release of dangerous substances may be assessed indirectly by controlling the content of the substance concerned; – durability may be assessed indirectly by controlling the production processes according to this document; Note 1: Products CE marked in accordance with appropriate harmonised European specifications may be presumed to have the performances stated with the CE marking.
Note 2: There may be a need to involve a third party for the purpose of regulatory marking (see Annex ZA).

All characteristics in 4.2.2 shall be subject to initial type tests in accordance with Clause 5.2.1. 5.3 Factory production control and inspection of samples in accordance with a prescribed test plan (see 5.1, 1a and b) Factory production control means the permanent internal control of production exercised by the manufacturer
All elements, requirements and provisions adopted by the manufacturer shall be documented in a systematic manner in the form of written policies and procedures. This production control system documentation shall ensure a common understanding of quality assurance and enable the achievement of the required product characteristics and the effective operation of the production control system to be checked. Factory production control shall be according to Annex A of this document. Note 1: A factory production control system similar to EN ISO 9001 made product specific to this document is deemed to satisfy the requirements of this clause. Note 2: There may be a need to involve a third party for the purpose of regulatory marking (see Annex ZA). Annex A of this document also summarises the tests that shall be carried out by the manufacturer as part of the production control in the factory, and as further testing of samples taken at the factory in accordance with a prescribed test plan. 5.4 Initial inspection of factory and of factory production control (see 5.1, 1c) The initial inspection of the factory and of the factory production control shall be limited to the parameters listed in Table 3 in conjunction with Annex A.

When a major non-conformance is recorded, the inspection shall be repeated within two month. The frequency of production surveillance shall return to, or remain at twice a year. When the repeated inspection also results in a non-conformance, then the production shall be subject within two months to a repeated initial inspection of the factory and of the factory production control together with a surveillance inspection. When this repeated initial inspection and surveillance inspection also results in a major non-conformance then the products are considered as no longer conforming to this document. 6 Marking and/or labelling 6.1 General All voluntary marking and/or labelling shall comply with Annex B 3.
Care shall be taken to ensure that any voluntary marking and/or labelling does not cause confusion with respect to the mandatory requirements. Note:
All marking and/or labelling of product to demonstrate compliance with the regulatory requirement is detailed in Annex ZA. 6.2 Product marking There is no requirement to mark basic soda lime silicate glass products. 6.3 Product characteristics
The manufacturer or his agent shall organise a system of references that allows for the following:  identification of exactly which characteristics have to be assessed (see Clause 4.2);  those characteristics that will be assessed;  values, classes, categories, etc. that have been determined for those characteristics.
This system shall be documented as part of the evaluation of conformity.
6.4 “Characteristics/performance identification paper” The manufacturer shall prepare a “characteristics/performance identification paper” based on the information collected on the product characteristics (see 6.3). This document shall be part of the manufacturers technical file and is the basis for the accompanying information as required for regulatory purposes. The "characteristics/performance identification paper" can be a catalogue in any media format (paper, disk, website, etc.), always identifiable by the reference that accompanies the marking with the product. The catalogue shall contain the values or classes of the characteristics for which a performance is declared. If no performance is declared, an indication of no performance determined (NPD) shall be made. Note 1: The conditions of use of NPD are given in Annex ZA. Note2: The catalogue should not contain any information other than that relevant to the “characteristics/performance identification paper”.

Factory production control A.1 Factory Production Control Requirements A.1.1 General The FPC 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.
