Overview

EN 12859:2011 - Gypsum blocks: Definitions, requirements and test methods - is the CEN European Standard that defines the characteristics, performance criteria and test procedures for smooth-faced gypsum blocks intended primarily for non‑load bearing partitions, independent wall linings and fire protection of columns, lift shafts and service shafts. The standard excludes gypsum blocks thinner than 50 mm and gypsum storey‑height units, and it explicitly states gypsum blocks are not to be used for ceilings.

Key topics and technical requirements

EN 12859:2011 sets out mandatory performance characteristics and the reference test methods to verify them:

• Reaction to fire and resistance to fire (fire behaviour performance measured by European test methods).
• Direct airborne sound insulation (acoustic performance).
• Release of dangerous substances (health and environmental safety).
• Thermal resistance (calculated from thermal conductivity values given in the standard).

Additional product properties and test procedures included:

• Dimensions, tolerances and flatness (sampling and measurement rules).
• Dry density and convenience classes for density.
• pH classes for suitability and acceptance on site.
• Moisture content, bending strength, surface mass, water absorption (including hydrophobic products) and related test methods.
• Sampling rules for factory and independent acceptance testing, plus evaluation of conformity (initial type testing and factory production control).
• An informative annex on surface hardness and an Annex ZA addressing the relationship with EU Construction Products Directive and CE marking requirements.

Applications (practical value)

EN 12859:2011 is applied where reliable, standardized gypsum block performance is needed:

• Construction of non‑load bearing interior partitions and demountable walls.
• Independent wall linings for retrofit or new builds.
• Passive fire protection systems for structural elements, lift shafts and service shafts.
• Product specification and compliance documentation for tenders, building permits and CE marking.

Who should use this standard

• Gypsum block manufacturers (product specification, factory production control, CE marking).
• Test laboratories and inspectors (sampling, test methods, reporting).
• Architects, specifiers and consultants (selecting materials for acoustic, thermal and fire requirements).
• Contractors and installers (acceptance criteria and site verification).
• Regulatory bodies and certifiers (conformity assessment vs. EU directives).

Related standards & compliance

EN 12859:2011 sits within the family of gypsum product standards and links to other European test methods referenced for fire, acoustic and material testing. It supports conformity procedures (initial type testing, factory production control) and CE marking in line with the Construction Products Directive.

4.5 Release of dangerous substances NOTE For CE marking purposes, see Annex ZA.1, Note. 4.6 Dimensions and tolerances 4.6.1 Dimensions Gypsum block dimensions are determined by the thickness, the length and the height. The thickness shall be at least 50 mm and shall not exceed 150 mm. The length shall not exceed 1 000 mm. The height shall be determined in conjunction with the length so that the surface area of a block is at least 0,10 m2. NOTE Preferred dimensions are for thickness: 50 mm, 60 mm, 70 mm, 80 mm, 100 mm, for length : 666 mm and for height: 500 mm. In cavity gypsum blocks, the wall gypsum plaster shall be at least 15 mm thick throughout the block. The total cavity volume shall not exceed 40 %. 4.6.2 Tolerances The dimensions of individual blocks, when measured in accordance with 5.3, shall have tolerances as follows:  thickness: ± 0,5 mm;  length: ± 5 mm; SIST EN 12859:2011
