Examination methods: Preparation of the specimen: DIN EN 717-1iA (see 1.1 Volatile organic compounds) Test chamber specifications: DIN EN 717-1 with the following deviations: - no determination of the concentration equivalents; formaldehyde emission was measured as stated above

- size of test chamber: see test chamber volume - relative humidity: 50% - air exchange rate and placement: see 1.1 volatile organic compounds Test chamber emissions parameters: see 1.1 volatile organic compounds Air sample: taken 3 days after placement Analysis:: DIN EN 16000-3 Determination limit: 3 ug/m3= 0.003ppm Results: Substance: formaldehyde Concentration (air in test chamber) ug/m3: <3 Concentration (air in test chamber) ppm: <0.003 Cologne, 17 November 2009 --------------------------------------------------------------------------------------------------------------------Page 11 Assessor evaluation Emission measurements were taken in a test chamber on a specimen of ControllRInnerseal provided by BetonSeal GmbH & Co. KG in Cologne.

The results, documented in the examination report. led to the assessment below. The examination is based on the professional guidelines set by the office of Dr Zwiener relating to health and safety standards drawn up by the town council of the City of Cologne for building materials and construction projects.

Carcinogenic, mutagenic and reprotoxic compounds (CMR-VOC) were not detectable 3 days after placement in the test chamber.

The total volatile organic compounds (TVOC) 3 days after placement in the test chamber amounted to 10 ug/m3 and well below the reference level of 300 ug//m3.

The total VOC without LCI 3 days after placement in the test chamber amounted to 6 ug/m3 and was well below the reference level of 100 ug/m3.

VOC according to regulation (EG) No. 1272/2008: category carc.2, muta.2, repr.2; TRGS 905: C3, M3, R3; IARC: Group 2B; DFG MAK list: category lll3 not detectable 3 days after placement in the test chamber.

Semivolatile organic compounds (SVOC) were not detectable 3 days after placement in the test chamber.

The R value amounted to 0.002 which is well below the reference level of 1.0.

No formaldehyde was detectable 3 days after placement in the test chamber.

Page 12 Appendix Explanatory notes to the Specific Emissions Rate (SER) Rates of emission are measured under defined physical conditions (temperature, relative air humidity, placement, air exchange rate etc...).

Such test chamber results are only directly comparable if the experiments are conducted under the same conditions.

If variations in the physical conditions only affect the air exchange rate and/or the placement, results from SER (specific emissions rates) can be used as reference. The SER measures how much VOC is released from a given unit of specimen per hour.

The SER can be calculated for each individual component of VOC proved to be present. This calculation is based in the findings of the examination report with reference to the formulae below: The following can be taken as unit of specimen: L = length unit (m)

emissions relating to the length

A = area unit (m2)

emissions relating to the area

V = volume unit (m3)

emissions relating to the volume

U = (complete) unit

emissions relating to the complete unit

This means we can distinguish 4 dimensions of SER: Length specific

SER(l) in ug/m h

Area specific

SER(a) in ug/m2 h

Volume specific

SER(v) in ug/m3 h

Unit specific

SER(u) in ug/n h

The SER therefore represents a product specific rate that describes the mass of VOC emitted from the product per unit of time at a given interval after the beginning of the test.

SER = q . C q

specific air flow rate (quotient from the air exchange rate and the placement)

C

Concentration of the measured substances

The results can be quoted in microgrammes (ug) or milligrammes (mg). 1mg = 1000 ug
