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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 20182 was prepared by Technical Committee ISO/TC 33, Refractories in collaboration with Technical
Committee CEN/TC 187, Rerfractory products and materials.
This second edition cancels and replaces the first edition (ISO 20182:2005), which has been technically
revised as follows:
⎯ in 6.5, two acceptable support plates are now specified;
⎯ in Clause 8, pH determination has been added in place of water hardness testing and predamping
percentages are now given for both dense and insulating castables;
⎯ in Clause 9 test report item c), the water pH, if determined, replaces the water hardness;
⎯ in Clause 9 test report item d), by agreement between the interested parties, the total water content and
rebound are measured and recorded.
Annex A has been added, giving procedures for the determination of the total water content and rebound.

INTERNATIONAL STANDARD ISO 20182:2008(E)
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.
NOTE The values obtained from test pieces cut from the panel prepared using this method might not correspond with
those obtained from test pieces of the same material prepared at a gunning installation site.
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.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

scheme
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 836 and the following apply.
3.1
gun
assembly essentially comprising a chamber into which the refractory is added, together with a mechanism that
controls the flow of the material through the unit
NOTE Depending on the type used, the gun may be open at the top, or a closed pressurized unit may be used.
3.2
rebound material
material that fails to adhere to the surface when being sprayed, and ricochets out of the immediate area
ISO 20182:2008(E)
4 Principle
Refractory material is conveyed pneumatically in either a dry or predampened form to the test site, using
equipment of the nozzle mixing type. Then water is introduced to the refractory mix at the nozzle and the
mixture is projected onto a support plate (see 6.5).
5 Precision
Differences between various types of equipment and in operator techniques may result in variations in the
physical properties of the gunned specimens. For referee testing, it is desirable that the same operator should
use the same equipment to produce test specimens.
6 Apparatus
6.1 Gun, of the pneumatic-nozzle mixing type.
6.2 Air compressor, capable of supplying a steady airflow at the required pressure and volume.
6.3 Mixer, for use when predamping is carried out. The mixer shall be capable of producing a
homogeneous mixture of the material to be tested.
6.4 Hose/nozzle assembly, comprising a reinforced pneumatic hose and a nozzle assembly suitable for
the material being gunned.
6.5 Gunned-material support plate, flat, capable of producing a panel having minimum usable
dimensions of 280 mm × 280 mm × 100 mm thickness that is suitable for the tests intended to be carried out,
after allowance for any material to be cut off as described in Clause 8. The preferred support plate has ledges
at both sides and the top edge. An example of the preferred support plate is given in Figure 1a).
An alternative support plate may be used, 300 mm to 500 mm in length, and having a bottom support edge
100 mm in width and of the same overall length as the support plate. An example of the alternative support
plate is given in Figure 1b).
The support plate may be made of wood or steel and shall not flex during use. The support plate may be
larger than the minimum panel size, to allow the edges to be removed from the gunned panel, for example, to
remove trapped rebound material at the bottom, and other edge effects.
Interested parties shall agree which type of panel is used. The test report shall state the dimensions of the
gunned-material support plate and panel produced, and the type of panel used.
6.6 Air pressure gauge, capable of measuring pressures up to 690 kPa, plus or minus 5 % at all
pressures.
6.7 Water-measuri
