oSIST prEN 1094-1:2005

Overview

prEN 1094-1 (CEN) is a European terminology standard for insulating refractory products, specifically defining terms used for soluble high‑temperature ceramic fibre products. The document (draft prEN 1094-1:2005) updates and will supersede EN 1094-1:1997 and is intended to ensure consistent naming and classification of ceramic fibre insulation across industry, procurement and testing activities.

Key topics

The standard focuses on clear, standardized definitions relevant to ceramic fibre insulation and includes:

• A precise definition of ceramic fibre: man‑made mineral fibre intended for heat‑insulating use and containing less than 2% (total weight) of alkaline and alkaline earth oxides.
• Terminology for product forms and states, for example:
  • Ceramic fibre bulk / loose fibre
  • Ceramic fibre mat
  • Ceramic fibre blanket
  • Ceramic fibre felt
  • Ceramic fibre board
  • Ceramic fibre paper
  • Pre‑formed shapes
  • Ceramic fibre yarn, rope, tape / textile
  • Ceramic fibre (castable / mouldable)
• Scope limitations and relationship to other parts of the EN 1094 series, which cover classification and test methods for shaped and ceramic fibre products.

Practical applications

prEN 1094-1 is a foundational reference for organizations that design, specify, manufacture, test or procure refractory insulation. Typical uses include:

• Creating consistent product datasheets and technical specifications for insulating refractory products.
• Ensuring clear communication between manufacturers, suppliers, testing laboratories and end users (furnace builders, steel, petrochemical, power generation, ceramics industries).
• Supporting procurement, quality control, labelling and regulatory compliance by providing unambiguous product terminology.
• Serving as the basis for harmonized classification and test standards in other parts of the EN 1094 series.

Who should use this standard

• Product engineers and R&D teams developing ceramic fibre insulation
• Specification writers and purchasing departments
• Test laboratories and certification bodies
• Standards committees and technical authoring teams
• Industrial end users (high‑temperature insulation, furnaces, kilns, thermal process equipment)

Related standards

EN 1094 is a multipart series. Relevant parts to consult alongside prEN 1094-1 include:

• Part 2: Classification of shaped products
• Part 3: Classification of ceramic fibre products (ENV)
• Parts 4–7: Test methods (bulk density, cold crushing strength, dimensional change on heating, methods of test)
