ISO 1927-3:2012 specifies the methods for the characterization of monolithic (unshaped) refractory materials as received and for checking the homogeneity of a delivery of a product. It is applicable to castables (dense and insulating), gunning materials tap hole clay, injection mixes, dry vibrating mixes, and ramming materials, as defined in ISO 1927-1.

Overview

ISO 1927-3:2012 - "Monolithic (unshaped) refractory products - Part 3: Characterization as received" defines standardized methods for characterizing monolithic (unshaped) refractory materials at the time of receipt. The standard applies to castables (dense and insulating), gunning materials, tap-hole clay, injection mixes, dry vibrating mixes and ramming materials (as defined in ISO 1927‑1). Its purpose is to support incoming inspection, verify delivery homogeneity and provide consistent test data for quality control and specification compliance.

Key topics and technical requirements

Principle: Characterization is focused on key determinations - chemical composition, grain‑size distribution (sieve analysis), moisture content (for ramming materials) and workability index (for wet ramming materials). Not all tests are mandatory for every product.

Sampling: Samples must be taken and reduced in accordance with ISO 1927‑2 (sampling for testing).

Chemical composition: Methods reference established ISO procedures (for example ISO 12677, ISO 21587, ISO 21068 and others). The test report must state which analytical method was used.

Grain‑size distribution: Measured by sieve analysis using sieves conforming to ISO 565. Sample quantities depend on maximum grain size (e.g., up to 2 mm → 100 g; up to 6 mm → 250 g; up to 10 mm → 500 g; above 10 mm → 1 000 g). Procedures cover drying (generally at 110 ± 5 °C), sieving apparatus characteristics and special treatment for materials containing oil or tar (Soxhlet extraction with toluene).

Moisture content: Procedure and separate sampling for moisture determination to avoid hardening during sieving.

Workability index: Defined test procedure and apparatus to assess handling properties of wet ramming mixes.

Test reporting: Results and applied methods must be clearly recorded; an informative checklist of appropriate tests is provided in Annex A.

Practical applications

Incoming inspection of monolithic refractory deliveries to confirm specification compliance and batch homogeneity.

Quality control in refractory manufacturing (castables, gunning mixes, ramming mixes).

Procurement and acceptance testing for steel, cement, glass and kiln operators who use refractories.

Research, failure analysis and materials development where reproducible characterization of unshaped refractories is required.
