Overview

EN 13279-2:2014 - "Gypsum binders and gypsum plasters - Part 2: Test methods" (CEN) defines the reference laboratory test methods for all gypsum binders and gypsum plasters covered by EN 13279‑1. It standardizes sampling, test atmosphere, apparatus and step‑by‑step procedures so that results (fineness, chemical composition, setting, mechanical properties, adhesion, etc.) are reproducible and comparable across European test labs and manufacturers.

Key Topics

• Scope and test conditions
  • Reference test atmosphere: (23 ± 2) °C and (50 ± 5) % RH.
  • Sampling and sample preparation requirements (hermetically sealed samples, homogenisation, grinding for chemical analysis).
• Sampling & apparatus
  • Requirements for leak‑free, non‑reactive gauging equipment (glass, stainless steel, hard rubber, plastics).
  • Emphasis on equipment cleanliness to avoid dihydrate contamination affecting setting.
• Fineness / sieve analysis
  • Control sieves and specific meshes used for product types (e.g. 5 000 µm, 1 500 µm, 200 µm, 100 µm) and defined sieving procedures.
• Chemical analysis
  • Determination of sulphur trioxide (SO3) and calculation of equivalent calcium sulfate via an HCl digestion and gravimetric barium sulfate determination.
• Water/plaster ratio
  • Multiple methods (sprinkling, dispersal/flow table, other gauging techniques) for determining optimum water/plaster ratios for binders and plasters.
• Setting time
  • Prescribed procedures (knife method, Vicat cone) for measuring setting characteristics.
• Mechanical properties & adhesion
  • Preparation of test specimens and methods for hardness, flexural strength, compressive strength, and adhesion assessment.
• Informative annex
  • Annex A on water retention as an informative guide.

Applications

• Ensures consistent, comparable test methods for:
  • Gypsum binder and plaster manufacturers for quality control.
  • Independent testing laboratories for product certification and compliance testing.
  • Specifiers, architects and contractors who require verified performance data for selection and performance verification.
  • Regulatory bodies and standards committees assessing conformity with EN 13279 series.
• Useful when preparing technical datasheets, CE marking documentation, tender specifications, or performance comparisons between gypsum products.

Related Standards

• EN 13279‑1: (Definitions and requirements) - companion document defining product classes and requirements.
• EN 196‑1, EN 196‑7 (cement testing and sampling methods) - referenced test practice influences.
• EN 459‑2 (building lime - test methods)
• EN 932‑1 (aggregate sampling)
• ISO 565 (test sieves)
