   -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

Provides procedures for the determination of thermal properties of masonry and masonry products.
