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 1927-2 was prepared by Technical Committee ISO/TC 33, Refractories.
ISO 1927 consists of the following parts, under the general title Monolithic (unshaped) refractory products:
— Part 1: Introduction and classification
— Part 2: Sampling for testing
— Part 3: Characterization as received
— Part 4: Determination of consistency of castables
— Part 5: Preparation and treatment of test pieces
— Part 6: Measurement of physical properties

Monolithic (unshaped) refractory materials —
Part 2:
Sampling for testing
1 Scope
This part of ISO 1927 gives guidance on the sampling of monolithic (unshaped) refractory materials for the
purpose of inspection and testing for quality and general information on the reduction and treatment of samples
prior to testing. It covers all materials formulated as monolithic refractory materials.
NOTE The term “monolithic” is the preferred term, whereas “unshaped” is commonly used in Europe. For the purposes
of this part of ISO 1927, the terms “monolithic” and “unshaped” can be used interchangeably.
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.
ISO 5022, Shaped refractory products – Sampling and acceptance testing
ISO 8656-1, Refractory products — Sampling of raw materials and unshaped products — Part 1: Sampling scheme
ISO 10725, Acceptance sampling plans and procedures for the inspection of bulk materials
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
batch
quantity of material from which a sample is to be achieved for testing to determine the quality of the material
NOTE A batch consists of material characterized as being of the same type, composition, grading and which, as far
as practical, has been manufactured under the same conditions.
3.2
consignment
quantity of material supplied at one time
NOTE A consignment may consist of one or more batches or parts of batches.
3.3
unit package
packaged part of a batch which can be a bag or a big bag (castables, gunning material, ramming mixes), a
carton (plastics), wrapped block (tap-hole mixes), a drum or a can (injection material, refractory grout)
NOTE A pallet is not a unit package.
3.4
increment
quantity of material taken at one time from a larger quantity
ISO 1927-2:2012(E)
3.4.1
elementary increment
quantity of material taken at one time from a unit package
NOTE This operation repeated a number of times will constitute a package increment after mixing.
3.4.2
package increment
increment that is representative of the unit package
NOTE 1 It can be the unit package itself or the result of mixing a certain number of elementary increments.
NOTE 2 The mass and number of elementary increments which are necessary to form the package increment are
defined in accordance with ISO 8656-1.
3.4.3
laboratory increment
package increment that has been reduced by an approved method
3.4.4
test-piece increment
test bars or cylinders obtained by shaping the laboratory increment necessary to carry out several physical tests
EXAMPLE Castable test bars for cold modulus of rupture testing.
3.5
sample
one or more increments taken from a batch which are to be used to provide information on the batch and to
allow a decision concerning the quality of the batch
3.5.1
batch sample
set of package increments representative of the batch
NOTE The number of package increments which are to form the batch sample should be agreed by the principal
parties involved. ISO 5022 or other sampling schemes may be used.
3.5.2
laboratory sample
set of laboratory increments
NOTE The number of laboratory increments is the same as the number of package increments.
3.5.3
test-piece sample
set of test-piece increments
NOTE The number of test increments can be higher than the number of laboratory increments and is governed by
international test standards.
4 Sampling scheme
4.1 General principles
4.1.1 It is essential that the adoption of a particular sampling scheme be agreed by the principal parties and
that a detailed sampling plan be documented and made available to those responsible for the taking and testing
of the increments. The basic framework of a scheme requires decisions and documentation on the following:
a) the constitution and description of the total material to be sampled;
b) the identification of batches and quantities which make up the total material;

ISO 1927-2:2012(E)
c) the type of packaging and mass content for each type of material;
d) the parties responsible for sampling and testing who may be third parties;
e) the location, timing and method of sampling;
f) the level of sampling, populat
