Hardcopy , PDF
English
30-04-2012
Foreword
Introduction
1 Scope
2 Normative references
3 Terms, definitions and symbols
4 Procedures to determine lambda[10,dry,unit]
-values for solid masonry units and lambda
[10,dry,mor]-values for mortars
5 Procedures to determine lambda[10,dry,unit]-values
for masonry units with formed voids and composite
masonry units
6. Moisture conversion
7 Procedures to determine design thermal values
([Rdesign, mas or lambdadesign, mas]) for masonry
built from masonry units and mortar
8. Determination of the thermal transmittance of masonry
9. Rounding rules design lambda-values for masonry
Annex A (normative) - Tabulated lambda[10,dry,mat]-values
of materials used for masonry products and
mortar products
Annex B (informative) - R[dry,mas] - or lambda[10,dry,
mas]-values of masonry built from a range of
masonry units containing formed voids
Annex C (informative) - Example how to use the table
in annex B
Annex D (normative) - Requirements for appropriate
calculation procedures
Annex E (informative) - Evaluation of conformity
Annex F (informative) - Alternative procedure for
the moisture correction of units with formed
voids
