European foreword

This document (EN 993‑1:2018) has been prepared by Technical Committee CEN/TC 187 “Refractory products and materials”, the secretariat of which is held by BSI.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2019, and conflicting national standards shall be withdrawn at the latest by June 2019.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

This document supersedes EN 993‑1:1995.

It is closely based on the corresponding International Standard, ISO 5017 “Dense shaped refractory products - Determination of bulk density, apparent porosity and true porosity”.

Reproducibility and repeatability data are available only for a limited number of testing methods and materials, but may be complemented in subsequent edition.

The series of standards EN 993 'Methods of test for dense shaped refractory products' consists of 20 Parts, some of which have been withdrawn and replaced by equivalent standards:

— Part 1: Determination of bulk density and porosity
— Part 2: Determination of true density
— Part 3: Test methods for carbon-containing refractories
— Part 4: Determination of permeability to gases
— Part 5: Determination of cold crushing strength
— Part 6: Determination of modulus rupture, ambient temperatures
— Part 7: Determination of modulus of rupture, elevated temperatures
— Part 8 Determination of refractoriness under load – withdrawn – replaced by EN ISO 1893
— Part 9: Determination of creep in compression
— Part 10: Determination of permanent change in dimensions on heating
— Part 11: Determination of resistance to thermal shock (ENV)
— Part 12: Determination of pyrometric cone equivalent
— Part 13: Specification for pyrometric cones
— Part 14: Determination of thermal conductivity (hot wire, cross array) – withdrawn – replaced by EN ISO 8894‑1
— Part 15: Determination of thermal conductivity (hot wire, parallel)
— Part 16: Determination of resistance to acids
— Part 17: Determination of bulk density of granular material (mercury method)
— Part 18: Determination of bulk density of granular material (water method)
— Part 19: Determination of thermal expansion by a differential method
— Part 20: Determination of resistance to abrasion at ambient temperature – withdrawn – replaced by EN ISO 16282
