BS ISO 2219:2010 pdf download.Thermal insulation products for buildings — Factory-made products of expanded cork (ICB)- Specification.
BS ISO 2219 specifies the requirements for factory-made products of expanded cork, which are used for the thermal insulation of buildings. The products are made with granulated cork agglomerated without additional binders and are delivered as boards without facings.
This International Standard describes product characteristics and includes procedures foi testing, evaluation of conformity, marking, labelling and packaging.
Products covered in this International Standard are also used in prefabricated thermal insulation systems and composite panels; the performance of systems incorporating these products is not covered.
This International Standard does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application are to be found in regulations or non-conflicting standards.
Products with a declared thermal resistance lower than 0,25 m2KIW, at 10 °C, or a declared thermal conductivity greater than 0.060 Wl(m.K). at 10 °C, are not covered in this International Standard.

3.2 level given value which is the upper or lower limit of a requirement
5 Requirements
5.1 General
Product properties shall be assessed in accordance with Clause 6. To comply with this International Standard,products shall meet the requirements of 5.2 and of 5.3, as appropriate.
One test result for a product property is the average of the measured values on the number of specimens given in Table 6.
5.2 For all applications
