Issue ( ) Applicant: Wacker-Chemie GmbH Friedrich-von-Heyden Platz Nünchritz Date of submission of application: Reference: S-S-F-1 Date of receipt: Content of application: Tests for development of construction material class B 1 (not readily igniting material) according to standard DIN : para Name: Siliconhermetic "Elastosil 7600". Notice: If the abovementioned construction material is not used for the purposes described in regulation MBO 2 para. 9 p.1, the general construction inspection test certificate is not required. This test certificate is not valid if the tested construction material is used as building product for the purposes set forth in the Federal State Civil Engineering Regulation (MBO 20 para. 3). This test certificate does not substitute the certificate required by Federal State construction/construction inspection regulations in certain cases. In the procedure of construction inspection, this test certificate can be seen as a supporting document: - for the certificate of approval in the case of standardized building products - for an applicability certificate for non-standardized building products. The certificate for aging-resistance according to standard DIN para. 6.2 is not submitted. Follow the guidance of standard DIN : annex D, specially the provisions for external inspection. The test certificate comprises 5 pages and 3 annexes. For publishing (also partially) the contents of the test certificate and referral to the tests for commercial purposes, the written permission of the testing body is required in every individual case. The first and the last page of this test certificate have to be affixed with a seal. The test material is used.

Test material: Date of reception of the test material: Sampling: by applicant Product name given by applicant: "Elastosil 7600". Description: RTV-1-siliconhermetic, name "Elastosil 7600", in a tube made of metal or monolith mineral construction materials. Tube measures: length 100 cm width 4 cm depth 2 cm Table 1: thickness, mass per surface unit, apparent density minimal measured value arithmetic mean maximal measured value thickness (6 measured values pro sample) [mm] u 20 mass per surface unit [kg/m 2 ] apparent density [kg/m 3 ] u 1501 Special notices: material was tested in a filled tube with two Eterplan-N strips or in a completely filled tube between two U-sheets (L 100 cm W 7, 5 cm H 2 cm).

5 Test certificate Nr. 3666/4421-a -Fe/Wi- page 5 3. Evaluation: - All samples met the average flammability requirements (class B2) set forth in DIN : para With none of the samples falling (droplets) of material or ignition of the filter paper occurred. - All samples tested in the combustion chamber met the requirements set forth in DIN : para The tested material can therefore be classified as not readily igniting material according to the standard DIN : (civil engineering materials class B1). 4. Special notice: 4.1 This fire test result is valid only for the civil engineering material described in para. 1. The use of this material in combination with other building materials (e.g. overlays, fire stop equipment) can influence the burning characteristics of this material in a way that the above mentioned classification becomes invalid. The burning characteristics of this building material in conjunction with other materials need to be tested separately according to the standard DIN According to the standard DIN : materials need to be marked with the following notice: DIN 4102-B1 4.3 The validity of the test certificate 3666/4421-a expires on A renewal can only be made taking into account future requirements of the construction inspection.
