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
— Part 7: Tests on pre-formed shapes
— Part 8: Determination of complementary 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

---------------------- Page: 11 ----------------------
SIST EN ISO 1927-2:2013
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;

2 © ISO 2012 – All rights reserved
---------------------- Page: 12 ----------------------
SIST EN ISO 1927-2:2013
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, population of increments;
g) the properties to be measured;
h) the methods of test (reference to International Standard number);

i) the criteria for assessing values of measured properties for deciding batch quality.

4.1.2 In all cases during sampling, increment division, preparation and storage of the increments, care shall

be taken to protect against any changes in the properties to be tested.

4.1.3 Sampling shall be performed under the supervision of a person having adequate experience on

sampling. The sampler shall be approved either by the interested parties or by the appropriate body or bodies.

The sampler shall be informed of the aim of the sampling.

4.1.4 When individual batches are identified, agreement should be made between the parties on whether, or

to what degree, a large batch should be subdivided into smaller batches. This may be undertaken to avoid the

possibility of the whole of a large batch being rejected because of a problem with a proportion of it.

4.1.5 When a sample is required for third-party certification of factory production control as the product is

being made, the sample shall be achieved by the same method that the producer uses to obtain a sample for

production control purposes.

4.1.6 Where required, the consignment may be subdivided into individual test batches, for example, if it is

clear that the consignment consists of various batches or should be treated in separate partial quantities.

4.1.7 The sampling framework is presented in Figures A.1 to A.3.
4.2 Procurement of the batch sample
4.2.1 Method

Identify the test batch, i.e. of the consignment or part of the consignment to be sampled (nature of the product,

mass, transport conditions, etc.).

Identify the unit package. The average mass (m) of this unit package shall be known.

Obtain the number of package increments which form the batch sample as agreed between parties. The

sampling scheme of ISO 5022 can be agreed by the parties if the unit packages, considered as equivalent to

shaped pieces, weigh less than 35 kg.
Randomly, select this number of the unit packages from the batch.

Proceed to sample the selected unit packages, if their mass is more than 35 kg. This means obtain a package

increment of each of these unit packages. In this case, ISO 8656-1 shall be applied to determine the mass and

the number of elementary increments which are necessary to obtain the package increment:

a) Estimate the maximum grain size of the material. This estimation is important because the minimum

mass of the elementary increment shall be determined, taking into account the maximum grain size of the

material in order to avoid systematic errors during sampling (see Table 1).
