Full title and description

ISO 10081-4:2014 — Classification of dense shaped refractory products — Part 4: Special products. This International Standard specifies the classification and designation of dense shaped refractory products of special composition (oxide products; oxide and non-oxide products; non-oxide silicon carbide or carbon-based products; and other special products which may be designated but not classified, e.g. borides or nitrides).

Abstract

Provides rules for classifying and designating “special” dense shaped refractories that fall outside the basic alumina‑silica and basic carbon‑containing product categories. The standard defines product types, groups, nature and state of raw materials, bonding systems, post‑treatment and designation conventions to ensure consistent identification and specification of special refractory products.

Scope

ISO 10081-4:2014 applies to dense shaped refractory products of special composition that are not covered by the basic product parts of the ISO 10081 series. It sets out classification principles and designation rules for diverse product families including oxide products, mixed oxide/non‑oxide products, silicon carbide or carbon‑based non‑oxide products, and other special chemistries (for example borides or nitrides) which may be designated but not fully classified under the same criteria as basic product families. The standard describes classification parameters such as product type, group, raw material nature and state, bond type and post‑treatment.

Key topics and requirements

• Definition of “special” dense shaped refractory product types and assignment of product groups.
• Designation rules covering nature and state of raw materials (oxide vs non‑oxide; carbon‑based; mixed compositions).
• Classification elements for bonding systems (e.g., chemical/ceramic bonds) and post‑treatment processes.
• Guidance for products that are designated only (not fully classified) such as some boride or nitride refractories.
• Standardized designation syntax to support unambiguous product identification in specifications and procurement.

Typical use and users

Used by refractory manufacturers, product development and quality departments, materials engineers, procurement/specification authors, testing laboratories and standards committees to classify, name and specify special dense shaped refractory products consistently across supply chains and technical documentation. It is referenced where standardized product designation improves communication between suppliers and end users in high‑temperature industries (metallurgy, glass, cement, ceramics, petrochemical).

FAQ

Q: What is this standard?

A: ISO 10081-4:2014 is the International Standard that defines the classification and designation scheme for “special” dense shaped refractory products—those with oxide, non‑oxide or mixed chemistries and other special compositions.

Q: What does it cover?

A: It covers classification elements (type, group), nature and state of raw materials, bond types, post‑treatment, and rules for designating products that cannot be classified under the basic product parts of the ISO 10081 series. It also identifies product families that are designated rather than classified.

Q: Who typically uses it?

A: Manufacturers, materials and process engineers, quality/control and testing laboratories, procurement/spec writers, and standards committees working with high‑temperature materials and refractory product specification.

Q: Is it current or superseded?

A: The 2014 second edition is published and listed as the current/confirmed edition (it replaced the 2007 edition). Users should check their national adoption bodies for any later confirmations or amendments.

Q: Is it part of a series?

A: Yes — ISO 10081 is a multi‑part series addressing classification of dense shaped refractory products. Other parts cover alumina‑silica and basic carbon‑containing product families (for example ISO 10081-1, -2 and -3).

Q: What are the key keywords?

A: Refractories, dense shaped, special products, oxide, non‑oxide, silicon carbide, carbon‑based, boride, nitride, classification, designation, ISO 10081.
