Monolithic (unshaped) refractory products - Part 6: Measurement of physical properties (ISO 1927-6:2012)

ISO 1927-6:2012 specifies methods for the determination of properties of unshaped materials from test pieces prepared and stored according to ISO 1927-5:2012.
The methods are applicable to dense and insulating castables and to ramming materials (including plastics) as defined in ISO 1927-1:2012 before and after firing.

Ungeformte (monolithische) feuerfeste Erzeugnisse - Teil 6: Bestimmung der physikalischen Eigenschaften (ISO 1927-6:2012)

Dieser Teil der ISO 1927 legt Verfahren zur Bestimmung der Eigenschaften ungeformter Werkstoffe an Probekörpern, die nach ISO 1927-5 hergestellt und gelagert werden, fest.
Die Verfahren gelten für dichte und wärmedämmende Feuerbetone und Rammmassen (einschließlich plastischer Massen), wie in ISO 1927-1 definiert, im ungebrannten und gebrannten Zustand.

Produits réfractaires monolithiques (non façonnés) - Partie 6: Détermination des propriétés physiques (ISO 1927-6:2012)

Overview

EN ISO 1927-6:2012 - "Monolithic (unshaped) refractory products - Part 6: Measurement of physical properties" (published December 2012) specifies standardized laboratory methods for measuring the physical properties of unshaped refractory materials. It applies to dense and insulating castables and to ramming materials (including plastics), for specimens prepared and stored in accordance with ISO 1927-5. The document is intended for use both before and after firing and supersedes EN 1402-6:2003.

Key topics

The standard defines test methods, specimen requirements and reporting for core physical-property tests, including:

• Geometric bulk density - geometric method using measured dimensions and mass (requires balance and callipers). Accepted test-piece shapes:
  • Shape A: 230 × 114 × 64 mm
  • Shape B: 230 × 64 × 54 mm
  • Shape C: 230 × 64 × 64 mm
  • Shape D: 160 × 40 × 40 mm
  • Alternative: 50 mm ±1 mm diameter and height cylinders for ramming materials
• Density and porosity - bulk density and apparent/true porosity measurements (water absorption methods where appropriate; insulating materials use geometric methods)
• Cold modulus of rupture and cold crushing strength - ambient mechanical strength determinations
• Permanent linear change - dimensional stability before/after firing
• Modulus of rupture at elevated temperatures - high-temperature strength testing
• Refractoriness under load and creep in compression - tests for deformation and creep under load at temperature
• Test reporting - required data and conditions to ensure reproducibility and traceability

Practical applications

EN ISO 1927-6 is used to:

• Establish quality control procedures for monolithic refractory production (castables, ramming mixes)
• Verify conformity to material specifications and acceptance criteria
• Support product development and R&D (comparing formulations, optimizing performance)
• Provide consistent test data for thermal and mechanical design of furnaces, kilns, ladles and other high-temperature equipment
• Facilitate supplier and purchaser communication with standardized measurement results

Who uses this standard

• Refractory manufacturers and formulators (quality labs)
• Third‑party test laboratories and certification bodies
• End users: steel, cement, glass, petrochemical and power plant operators
• R&D engineers and materials scientists working on refractory development
• Standards committees and procurement teams specifying material acceptance

Related standards

Normative references and related test standards (as cited in EN ISO 1927-6) include:

• ISO 1927-5 (preparation and treatment of test pieces)
• ISO 1893 (refractoriness under load)
• ISO 5013 / ISO 5014 / ISO 5017 / ISO 5018 (various density and strength methods)
• ISO 3187 (creep in compression)

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 electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 1927-6 was prepared by Technical Committee ISO/TC 33, Refractories.
ISO 1927 consists of the following parts, under the general title Monolithic (unshaped) refractory products:
— Part 1: Introduction and classification
— Part 2: Sampling for testing
— Part 3: Characterization as received
— Part 4: Determination of consistency of castables
— Part 5: Preparation and treatment of test pieces
