ISO 23993:2008(E) iv © ISO 2008 – All rights reserved 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 23993 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 89, Thermal performance of buildings and building components, in collaboration with ISO Technical Committee ISO/TC 163, Thermal performance and energy use in the built environment, Subcommittee SC 2, Calculation methods, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). This International Standard is one of a series of standards on methods for the design and evaluation of the thermal performance of building equipment and industrial installations. This corrected version of ISO 23993:2008 incorporates the following corrections plus other minor editorial modifications. Clause 4: The following two rows have been added to the table: N number of spacers per square metre —
∆λsq=thermal conductivity per spacer per square metre W/(m.K)
Clause 6: Equations (1) and (2) have been re-inserted: dF=+∆λλλ (1) macdjCFFFFFFFF∆θ= (2) 7.9.2.2: The calculations have been modified as follows (i.e. with the substitution of ∆λsq, the thermal conductivity per spacer per square metre, for ∆λ= i.e., with the deletion of “/spacers/m2” from the units): Spacers of steel in the form of a flat bar 30 mm × 3 mm ∆λsq = 0,003 5 W/(m·K) 40 mm × 4 mm ∆λsq = 0,006 0 W/(m·K) 50 mm × 5 mm ∆λsq= 0,008 5 W/(m·K) SIST EN ISO 23993:2011
ISO 23993:2008(E) © ISO 2008 – All rights reserved vA new Equation (6) has been added to define the relationship between ∆λ and ∆λsq and the original Equation (6) renumbered to Equation (7). 7.9.3: The units “W(m·K)” have been corrected to “W/(m·K)”. A.4.1 (twice) and A.4.2 (twice): The term “specific” has been added to the definition of W, “specific airflow resistance.” Annex B: The additional subtitles and introductory text, “B.1
Insulation materials” and “B.2
Conditions” have been added. The line “Determination of the conversion factors and ∆λ” has been restyled as B.3 and introductory text added. Table C.1: The vertical line separating the subheadings “calcium-magnesium silicate fibre” and “calcium silicate” and “microporous insulants” each from the subheading “Insulation” has been moved one column to the left, i.e. from between the pictures for the two pipes to between the column “Application.” and the picture of the horizontal pipe (consistent with other similar rows such as that for “mineral wool”). Table C.1 (four times): The term “airflow resistance” has been replaced with the term “airflow resistivity”. SIST EN ISO 23993:2011
ISO 23993:2008(E) vi © ISO 2008 – All rights reserved Introduction The establishment of design values for thermal conductivity for the calculation of the thermal performance of insulation systems for building equipment and industrial installations requires a consideration of various possible influences affecting the thermal properties of the insulation products employed due to the operational conditions of any individual insulation system. Among these influences could be: ⎯ the non-linearity of the thermal conductivity curve over the temperature range in which the insulant may be employed; ⎯ the thickness effect; ⎯ the effect of moisture in the insulant; ⎯ ageing effects, beyond those already incorporated in the declared value; ⎯ special installation effects such as single- or multi-layered installation.
