Overview

ISO 13765-6:2004 is an international standard issued by the International Organization for Standardization (ISO) that specifies the method for determining the moisture content of ready-mixed refractory mortars. Refractory mortars are specialized materials used in high-temperature industrial applications such as furnaces, kilns, and reactors. Accurate determination of moisture content is critical to ensure the quality, performance, and durability of these mortars in refractory linings. This standard provides a precise, reproducible procedure to measure moisture levels, supporting manufacturers, quality control laboratories, and end-users in maintaining consistent product specifications.

Key Topics

  • Scope and Application: Defines the method for determining moisture content specifically in ready-mixed refractory mortars.
  • Sampling Procedure: Recommends sampling in accordance with ISO 8656-1 or as agreed between parties, emphasizing obtaining a representative sample by thorough mixing without discarding the supernatant liquid.
  • Equipment Requirements:
    • Precision balance with ±0.1 g accuracy.
    • Electric drying oven capable of maintaining 110 °C ± 5 °C.
    • Desiccator for cooling samples after drying.
  • Test Method:
    1. Weigh approximately 50 g of mortar sample.
    2. Dry the sample in the oven at 110 °C until mass is constant (two consecutive weighings 10 minutes apart differ by less than 0.2 g or 0.5%).
    3. Cool in desiccator and weigh.
    4. Calculate moisture content based on weight loss using the formula:
      moisture content (%) = [(initial mass - dried mass) / initial mass] × 100.
  • Quality Assurance: Each sample is tested in duplicate, with averages reported. Results differing by more than 1% must be rejected and the test repeated.
  • Reporting Requirements: Specifies detailed information to be included in test reports, such as identification details, reference to the standard, testing organization, results, deviations, anomalies, and test date.

Applications

ISO 13765-6:2004 is essential for industries involved in the production and use of refractory mortars, including:

  • Refractory Manufacturers: Ensuring consistent moisture content in factory-mixed mortars to meet quality and performance criteria.
  • Quality Control Laboratories: Conducting moisture tests to monitor batch uniformity and adherence to specifications.
  • Industrial Maintenance: Verifying moisture levels in mortars used for repairs and installations in high-temperature processing equipment.
  • Research and Development: Assessing moisture impact on mortar properties and formulating improved refractory mixes.
  • Supply Chain Management: Validating moisture content upon receipt of premixed mortars to prevent quality issues.

By providing a standardized testing methodology, ISO 13765-6:2004 facilitates compliance with contractual requirements and enhances product reliability in demanding thermal environments.

Related Standards

ISO 13765 comprises a series of parts addressing different properties of refractory mortars. Related standards include:

  • ISO 13765-1: Determination of consistency using cone penetration method.
  • ISO 13765-2: Determination of consistency by the flow table method with alternating movement.
  • ISO 13765-3: Determination of joint stability.
  • ISO 13765-4: Determination of bond strength under flexural load.
  • ISO 13765-5: Determination of particle size distribution by sieving.

For sampling procedures linked to refractory products, see:

  • ISO 8656-1: Sampling of raw materials and unshaped refractory products - sampling scheme.

These standards collectively ensure comprehensive characterization and quality management of refractory mortars.

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.

L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec la
Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
