Overview

EN ISO 8394-2:2017 - Buildings and civil engineering works - Determination of extrudability for sealant - Part 2: Using standardized apparatus - specifies a laboratory method to determine the extrudability of sealants independently of the package in which they are supplied. Endorsed by CEN (as EN ISO 8394-2:2017), the standard defines test conditions, apparatus, conditioning and test procedures to produce comparable extrusion-rate results for single- and multi-component sealants.

Key topics and technical requirements

• Scope and principle

  • Measures extrudability by filling a standardized apparatus and extruding sealant under defined conditions; mass (and volume) of extrudate is recorded.
  • Comparison of results requires identical test conditions; any deviations must be reported.

• Apparatus and instruments

  • Regulated enclosure at specified temperatures: (5 ± 2) °C, (23 ± 2) °C, (35 ± 2) °C or an agreed temperature.
  • Pneumatic standardized apparatus with cylinder volumes of 250 ml or 400 ml and orifice diameters 2–10 mm (as agreed).
  • Compressed air supply (up to 700 kPa); typical test pressure specified as (300 ± 10) kPa unless otherwise agreed.
  • Timing and weighing: stopwatch (0.1 s) and balance (0.1 g).

• Conditioning and sampling

  • Sealant and cylinder conditioned in the regulated enclosure for a minimum of 12 hours (default 23 ± 2 °C).
  • Single-component: fill cylinder avoiding air bubbles.
  • Multi-component: mix per manufacturer instructions and test at three pot-life times - quarter, mid, and third-quarter of pot life.

• Test procedure

  • Remove air from orifice, then extrude for a defined time (default 30 s for single-component tests); weigh extruded mass immediately after extrusion.
  • Multi-component sealants: perform three extrusions at the defined pot-life times; for robustness, the protocol calls for multiple apparatus and repeats (nine tests total when specified).

• Expression of results

  • Results expressed as extrusion rate (g/min) and optionally volume per minute; standard provides formulae and rounding rules.

Applications and users

• Who uses it: sealant manufacturers, independent testing laboratories, quality control teams, construction specifiers, certification bodies, and procurement specialists.
• Practical uses:
  • Compare pumpability and workability of sealant formulations independently of cartridge or sausage packaging.
  • Support product development (rheology adjustments) and quality control sampling.
  • Provide objective data for technical datasheets, performance claims, and compliance in building and civil engineering projects.

Related standards

• ISO 6927 (Sealants - Vocabulary) is normative and referenced for terms/definitions.
• EN ISO 8394 series - Part 2 is one part of this series addressing extrudability; users should consult other parts for complementary test methods.

Keywords: EN ISO 8394-2:2017, extrudability, sealant testing, standardized apparatus, sealant extrusion rate, buildings and civil engineering, sealant quality control.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
