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.

Methods of test for dense shaped refractory products —
Determination of resistance to abrasion at ambient temperature
1Scope
This International Standard specifies a method intended primarily for the determination of the abrasion
resistance of shaped refractory materials at ambient temperature. It can also be used for unshaped refractory
materials. It provides an indication of the suitability of the material for service in abrasive or erosive conditions.
NOTE This International Standard is based on and technically identical to EN 993-20, published by the European
Committee for Standardization.
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

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
resistance to abrasion
resistance of refractory test pieces to the surface wear caused by the mechanical action of moving solids
3.2
resistance to erosion
resistance of refractory test pieces to the surface wear caused by the mechanical action of a fluid, which may or
may not contain solid material
4 Principle
The method determines the volume of material abraded from a flat surface of a test piece placed at right angles
to a nozzle through which 1 000 g of size-graded silicon carbide is blasted by compressed air at 450 kPa.
1) EN 993-1, which is referred to in the text of EN 993-20, is closely based on ISO 5017.

5 Apparatus
5.1 Abrasion tester, consisting of the equipment specified in 5.1.1 and 5.1.2.
5.1.1 Venturi blast assembly (see Figure 1) or blast gun (see Figure 2), consisting of a suitable housing with
an air nozzle delivering air into the barrel of the assembly which acts as a venturi tube, the abrasive entering the
barrel from the side. The air-delivery nozzle shall have an inlet inside diameter between 2,84 mm and 2,92 mm
and an outlet inside diameter between 2,36 mm and 2,44 mm. The air nozzle may be protected from abrasion
by covering it with a nominally 9,4 mm long piece of vinyl tubing of inside diameter 4,7 mm and wall thickness
1,5 mm. The inside diameter of the barrel of the assembly shall not exceed 10 mm and the barrel shall be
checked periodically for wear.
5.1.2 Nozzle (see Figures 1 and 2), for directing the abrading medium onto the test piece, consisting of a piece
of glass tubing 115 mm long, 7mm in outside diameter, with a nominally 1,1 mm thick wall. This glass tube is
attached to the blast assembly and held perpendicular to the test piece using a 70 mm long piece of stainless
steel tubing, 7,15 mm inside diameter. The steel tube is glued inside a 9,53 mm tubing nut which is screwed
onto the end of the blast assembly barrel. The glass tube is inserted through this steel tube and an air pressure
seal made using a suitable rubber grommet compressed when the tubing nut is attached to the assembly barrel.
The end of the glass tube within the blast assembly barrel shall be positioned at a distance of 2mm from the air-
delivery nozzle. This is achieved by placing the glass tube on a brass rod 4,5 mm in diameter, with a 7,9 mm
shoulder 117 mm from the tip. This allows the glass tube to be inserted through the steel tube and into the barrel
of the assembly until the end of the brass rod touches the air-delivery nozzle, thus ensuring a 2mm gap
between the end of the glass tube and the air-delivery nozzle.
A new piece of glass tubing shall be used for each determination.
5.2 Feed mechanism, capable of supplying 1 000 g of abrasive to the blast assembly in (450± 15) s.
Secondary air shall be allowed to enter the system with the abrasive. A suitable feed mechanism is shown in
Figures 3 and 4. It consists of three funnels:
a) an upper (charging) funnel;
b) a middle (feed control) funnel with a metal, glass or plastic orifice which provides the required feed rate;
c) a lower (delivery) funnel.
5.3 Test chamber (see Figure 3), consisting of a tightly sealed enclosure with a door to permit ready access
for mounting and removing the test pieces. The blast assembly is mounted vertically in the top of the test
chamber so that the downwa
