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 8143 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy use in the
built environment, Subcommittee SC 3, Thermal insulation products.

INTERNATIONAL STANDARD ISO 8143:2010(E)

Thermal insulation products for building equipment and
industrial installations — Calcium silicate products
1 Scope
This International Standard specifies the requirements for factory-made calcium silicate products which are
used for thermal insulation of industrial installations and building equipment with an operating temperature of
up to approximately +1 100 °C.
NOTE Calcium silicate products can be used at temperatures lower than 0 °C. For operating temperatures below
0 °C, special tests, regarding the suitability of the product in the intended application, are advised (e.g. liquefaction of
oxygen). It is advisable to seek the advice of the manufacturer(s) in all cases.
The products are manufactured in the form of boards, pipe sections, segments and prefabricated ware.
This International Standard describes product characteristics and includes procedures for testing, evaluation
of conformity, marking and labelling.
Products covered by this International Standard are also used in prefabricated thermal insulation systems and
composite panels; the structural performance of systems incorporating these products is not covered.
This International Standard does not specify the required level or class of a given property required to be
achieved by a product in order to demonstrate fitness for purpose in a particular application. The levels
required for a given application can be found in regulations and invitations to tender.
This International Standard is not applicable to
a) products with a declared thermal conductivity greater than 0,6 W/(m⋅K) at 23 °C;
b) products intended to be used for the insulation of the building structure;
c) the acoustical aspects
1) direct airborne sound insulation, and
2) impact noise transmission index.

3 Terms, definitions, symbols, units and abbreviated terms
3.1 Terms and definitions
For the purposes of this document the terms and definitions given in ISO 9229 and the following apply.
3.1.1
production line
equipment that produces products in a continuous process
NOTE For initial type test (ITT) and factory production control (FPC), each line is considered separately.

NOTE For ITT and FPC, units using the same process in one factory are considered together (as one production
line).
3.1.3
minimum service temperature
lowest temperature to which a thermal insulation product may be exposed at a given thickness and at which it
will continue to function within specified limits of performance
NOTE The required performance may be in the areas of dimensional stability, thermal properties and mechanical
properties.
