repeated without delay. 

2.3.3 Third party testing of the building products in the context of the proof of compliance 
2.3.3.1 External monitoring 
For the thermal insulation material, the fasteners (staples and Òfischer FAHKÒ only), the base plasters 
and the overall thermal insulation composite system, each factory shall subject the in-ternal production 
monitoring to regular external monitoring, however at least twice a year. At least the tests according to

3.3 Thermal insulation and climate-related moisture protection 
For the mathematical proof of the heat insulation of insulation boards (see Section 2.1.2) the rated value for the 
thermal conductivity is dependent upon the respective reference value in accordance with DIN V. 4108-4:200407, 
Table 2, Category 1. A rated value according to Category II applies for insulation boards in the case of which 
a limit value ..limit has been defined within the context of a proof of conformity based on a general building 
authority approval. 

The plaster system can be disregarded. 

The requirements of the climate-related moisture protection according to DIN 4108-3 shall be complied 
with. The specifications of Section 2.1.3 and Appendix 2 shall be used as mathematical values for the 
necessary proofs. 

In the case of particular winter weather situations and depending on the thermal insulation of the 
supporting wall construction the fastening elements may vary temporarily on the plaster surface with 
respect to the undisturbed wall due to differences in the formation of frost or defrost water.

is 6 - 8 mm thick, shall exhibit a d density of between 380 kg/m3 and 500 kg/m3. The density of the 


remaining insulation board shall be at least 140 kg/m3. Measured densities may be no more than 10% 
lower than the specified values. 

5. Test of Òfischer FAHKÒ fasteners 
The Òfischer FAHKÒ fasteners are also subject to the additional regulations of the testing and
