Full title and description

ISO 10059-1:2025 — Dense shaped refractory products — Determination of cold compressive strength — Part 1: Referee test without packing. This International Standard specifies a referee (reference) method for measuring the cold compressive strength of dense, shaped refractory products (e.g., standard bricks, special shapes and pre-cast items) using a test procedure without packing materials.

Abstract

This document specifies a method for the determination of the cold compressive strength of dense shaped refractory products. It is applicable to shaped refractories that have fixed geometry and dimensions when delivered to the user — including standard bricks, special shapes and pre-cast products — and defines the referee test procedure carried out without packing.

Scope

ISO 10059-1:2025 defines a standard referee test procedure without packing for determining the cold compressive strength of dense shaped refractory products. The scope covers shaped refractories that retain fixed geometry/dimensions on delivery and applies to standard bricks, special shapes and pre-cast products; it is intended as the reference method for comparing results and resolving disputes between laboratories or suppliers.

Key topics and requirements

• Definition of sample preparation and conditioning for dense shaped refractory products.
• Detailed referee test procedure for cold compressive strength measurement without using packing materials.
• Requirements for test equipment, loading rate, and specimen alignment to ensure reproducibility.
• Reporting requirements and how to present test results for comparison and certification.
• Relationship to alternative test method(s) (see Part 2 — test with packing) and guidance on when the referee method is appropriate.

Typical use and users

Primary users include refractory manufacturers, materials testing and quality control laboratories, third‑party testing bodies, procurement and specification engineers in industries using refractories (steel, glass, non‑ferrous metals, cement, ceramics), and standards committees involved in product specification and conformity assessment. The standard is used for routine QA comparisons, dispute resolution between parties, and calibration/reference testing.

Related standards

ISO 10059 series and related documents: ISO 10059-2:2003 (Test with packing — alternative method) remains relevant as the complementary test method; ISO 10059-1:2025 replaces the earlier ISO 10059-1:1992 edition. National/adopted versions (EN, BS, etc.) exist where the ISO text has been published as an identical or endorsed European/national standard.

FAQ

Q: What is this standard?

A: ISO 10059-1:2025 is an International Standard that specifies a referee (reference) laboratory method for determining the cold compressive strength of dense shaped refractory products using a test performed without packing materials.

Q: What does it cover?

A: It covers the test procedure, specimen preparation and conditioning, equipment and loading requirements, alignment and execution of the referee compressive test, and reporting of results for dense shaped refractories such as bricks, special shapes and pre-cast products.

Q: Who typically uses it?

A: Refractory manufacturers, independent test laboratories, quality and R&D departments in user industries (steel, glass, cement, ceramics), procurement/specification engineers, and standards bodies — especially where a reference method is needed for inter-laboratory comparison or dispute resolution.

Q: Is it current or superseded?

A: ISO 10059-1:2025 is the current (published) edition and replaces the previous ISO 10059-1:1992 edition. Part 2 (ISO 10059-2:2003) remains published and describes the alternative test with packing.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 10059 series dealing with cold compressive strength of dense shaped refractory products. Notably Part 2 (ISO 10059-2:2003) describes the test with packing. National/adopted versions (EN ISO, BS ISO, etc.) are available in some territories as identical or endorsed texts.

Q: What are the key keywords?

A: Refractories; dense shaped refractory products; cold compressive strength; referee test; test without packing; mechanical properties; ISO 10059.
