Refractory test-piece preparation - Gunning refractory panels by the pneumatic-nozzle mixing type guns (ISO/FDIS 20182:2024)
his International Standard describes the procedure for the preparation of test panels from refractory materials by gunning through pneumatic nozzle mixing type guns at ambient temperatures. The test pieces are for the determination of properties on as-gunned products prepared under either “standard conditions” (as required for quality assurance or product development) or “site conditions”. In the case of “site conditions”, the purpose of the testing is to establish the properties pertaining to a given installation or a given set of installation conditions. In this case, the panel is obtained during the on-site installation. Such parameters as ambient temperature, gunning elevation, air pressure and curing conditions (temperature, orientation of the panel) applying during the preparation of the panel are as near as possible to the same parameters pertaining to the site installation.
This International Standard does not apply to plastic gunning mixes and might not apply to those mixes that contain aggregates that are susceptible to hydration.
It also does not apply to shotcrete type mixes. (These are dealt with in ISO 18886, “Refractory test-piece preparation – Gunning refractory panels by wet gunning techniques.”).
Probenvorbereitung feuerfester Erzeugnisse - Probenvorbereitung feuerfester Spritzmassen mittels pneumatischer Spritzmaschinen (ISO/FDIS 20182:2024)
Dieses Dokument legt die Verfahrensweise für die Probenvorbereitung von Spritzmassen aus feuerfesten Werkstoffen mittels Spritzmaschinen bei Umgebungstemperaturen fest. Die Prüfstücke dienen der Bestimmung von Eigenschaften an Produkten im gespritzten Zustand, die entweder unter „Normbedingungen“ (wie für die Qualitätssicherung oder Produktentwicklung erforderlich) oder unter „Baustellenbedingungen“ hergestellt wurden. Im Falle von „Baustellenbedingungen“ besteht der Zweck der Prüfung darin, die Eigenschaften für eine bestimmte Installation oder eine bestimmte Reihe von Installationsbedingungen zu bestimmen. In diesem Fall kann die Spritzmasse während des Einbaus vor Ort erhalten werden. Parameter wie Umgebungstemperatur, Spritzhöhe, Luftdruck und Abbindebedingungen (Temperatur, Ausrichtung der Spritzmasse), die bei der Vorbereitung der Spritzmasse angewandt werden, entsprechen so weit wie möglich den Parametern, die auch bei der Installation vor Ort gelten.
Es ist auch möglich, bestimmte „Baustellenbedingungen“ durch das Spritzen von Spritzmassen außerhalb des Standortes, z. B. in einer Laborumgebung, zu simulieren. Dies ist nach diesem Dokument durch Vereinbarung zwischen den beteiligten Vertragspartnern zulässig.
Dieses Dokument ist nicht anwendbar gilt nicht für plastische Spritzmassen und Gemische, die hydratationsempfindliche Zuschlagstoffe enthalten.
Dieses Dokument ist nicht anwendbar für Spritzbeton-Gemische, die in ISO 18886 behandelt werden.
WARNUNG — Dieses Dokument kann den Einsatz von gefährlichen Stoffen, Arbeiten und Geräten einschließen. Sie ist nicht für die Erörterung der damit verbundenen Sicherheitsprobleme vorgesehen. Es liegt in der Verantwortung des Anwenders dieses Dokumentes, geeignete Maßnahmen für Sicherheit und Gesundheit zu ergreifen sowie die Gültigkeit gesetzlicher Einschränkungen vor der Anwendung zu bestimmen.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of
a patent. ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of
a patent which may be required to implement this document. However, implementers are cautioned
that this may not represent the latest information, which may be obtained from the patent database
available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent
rights.

This document was prepared by Technical Committee ISO/TC 33 Refractories.
This third edition cancels and replaces the second edition (ISO 20182:2008), which has been technically
revised.
The main changes are as follows:
— The scope has been broadened to include the preparation of gunned panels under both controlled
laboratory (“standard”) conditions and “site” conditions. This scope aligns with that in ISO18886
“Refractory test piece preparation – Gunning refractory panels by wet gunning techniques”.
— in 6.5, details of two acceptable support plates have been amended.
— In Clause 4, provision has been made for the use of a gunning liquid other than water and examples
of liquids other than water that might typically pertain, are given.
— in Clause 8, the hose diameters have been amended and details of hose lengths have been provided.
— in Clause 8, provision has been made for gunning materials containing stainless-steel wire fibres.
— in Clause 8, details of predamping have been relegated to inclusion only as a note (viz: NOTE 3).
— In Clause 8, in cases where a determination of water content on the gunned material is required,
options for the taking of the sample have been described and options for the nature of the moisture
determination have been permitted by agreement between interested parties.
— in Clause 9 test report item a), details of any stainless-steel wire fibre additions are to be reported.
— In Clause 9 test report item c), where a gunning liquid other than water is used, this must be specified.

as the basis for rebound calculations.

Refractory test-piece preparation — Gunning refractory
panels by the pneumatic-nozzle mixing type guns
WARNING — This International Standard may involve the use of hazardous materials, operations
and equipment. It does not attempt to address the safety problems associated with its use. It is
the responsibility of the user of this International Standard to establish appropriate safety and
health practices, and to determine the applicability of regulatory limitations prior to use.
1 Scope
This International Standard describes the procedure for the preparation of test panels from refractory
materials by gunning through pneumatic nozzle mixing type guns at ambient temperatures. The test
pieces are for the determination of properties on as-gunned products prepared under either “standard
conditions” (as required for quality assurance or product development) or “site conditions”. In the
case of “site conditions”, the purpose of the testing is to establish the properties pertaining to a given
installation or a given set of installation conditions. In this case, the panel may be obtained during
the on-site installation (see also the note below). Such parameters as ambient temperature, gunning
elevation, air pressure and curing conditions (temperature, orientation of the panel) applying during
the preparation of the panel are as near as possible to the same parameters pertaining to the site
installation.
NOTE It is also possible to simulate certain “site conditions” by gunning panels off-site, for example, in a
laboratory setting. This is permitted under this International Standard, by agreement between interested
parties.
This International Standard does not apply to plastic gunning mixes and might not apply to those mixes
that contain aggregates that are susceptible to hydration.
It also does not apply to shotcrete type mixes. (These are dealt with in ISO 18886, “Refractory test-
piece preparation – Gunning refractory panels by wet gunning techniques.”).
