EN 13999-1:2006 (E) 4 Introduction Solvent-free and low-solvent adhesives may release considerable long-term emissions of volatile chemical compounds. Any documentation of emission characteristics requires a test method which includes all relevant and potentially hazardous substances.
The test shall: • be reliable and reproducible; • give results in a short time to be useful for decisions for development projects; • verify that carcinogenic or sensitising volatile substances are absent; • characterise the emission properties of the adhesive. This can be achieved by sampling the atmosphere around the applied adhesive kept in an environmental test chamber at controlled ambient conditions.
EN 13999-1:2006 (E) 5 1 Scope This European Standard describes a conventional standard method for assessing potential emissions from adhesives after their application. This European Standard applies only to "solvent-free" and "low-solvent" adhesives as they are defined in EN 923. The adhesives shall be applicable at room temperature.

EN 13999-1:2006 (E) 6 3 Terms and definitions For the purposes of this European Standard the terms and definitions given in EN 923:2005, EN ISO 16000-9:2006, ISO 16000-6:2004 and the following apply. 3.1
specific cumulative emission
(SCE) total volatile organic compounds per unit of test area, emitted in a time interval between 24 h and 240 h after the start of the test 3.2
volatile organic compounds (VOC) organic compounds whose boiling point ranges from (50 °C to 100 °C) to (240 °C to 260 °C) and generally has a saturation pressure of 25 °C greater than 102 kPa 4 Principle The test determines the emissions of volatile organic substances from adhesive coatings. Very volatile and mainly particle bound compounds are not detected with the described procedures. The test is performed in an emission test chamber (Figure 1) at specified constant temperature, relative humidity, air mixing and air exchange. A measurement of the concentrations of the compounds of interest in the air of the exhaust pipe is considered representative of the air in the whole test chamber.
Sampling and analysis of the non-polar and slightly polar volatile organic compounds, as defined in ISO 16000-6, shall be carried out as described in ENV 13999-2. Sampling and analysis of the volatile aldehydes shall be carried out as described in ENV 13999-3. Sampling and analysis of the volatile isocyanates shall be carried out as described in ENV 13999-4. The test includes: • qualitative and quantitative determination of carcinogenic and sensitising substances in an early stage after the application of the adhesive sample; • determination of the VOC specific emission rate at three points of time, a determination of specific cumulative VOC emission in the interval between 24 h and 240 h. NOTE There are specific applications for which an emission test cell (as described in EN ISO 16000-10) may be easier to handle than the emission test chamber. In these cases it is possible to apply the procedures as given in this European Standard with the exception that a test cell is used instead of the test chamber. But, as the air flow rate across the sample is higher than with the chamber method, the results may only be used with supporting correlation data.
5 Apparatus The test apparatus shall be comprised of the following main components: support, air supply and mixing facilities, emission test chamber with monitoring and control systems, air sampling devices and devices for desorption and analysis. 5.1 Support
A stainless steel plate or a glass plate shall be used as a substrate for the adhesive to be applied.
EN 13999-1:2006 (E) 7 5.2 Adhesive coating device
A device able to ensure a uniform coating of the adhesive to the support (5.1) shall be used.
5.3 Emission test chamber
All the components of the chamber (see figure 1) and connected pipes and tubes that will be in contact with the vapours shall be low emitting and low adsorbing and shall not contribute to the emission test chamber background concentration. Polished stainless steel or glass shall be used to build the chamber structure. The internal volume of the chamber shall not be less than 0,004 m3, preferably from 0,1 m3 to 1 m3.
The emission test chamber shall be airtight in order to avoid uncontrolled air exchange with external air. The emission test chamber shall be operated slightly above atmospheric pressure to avoid any influence from the laboratory atmosphere. The emission test chamber is considered sufficiently airtight if at least one of the following requirements is fulfilled: • air leakage is less than 1/1 000 of the chamber volume per minute at an overpressure of 1 000 Pa; • air leakage in operating condition is less than 1% of the supply airflow rate.

Example of an emission test chamber 5.4 Air supply and mixing facilities The emission test chamber shall have facilities (e.g. electronic mass flow-meter controllers) capable of continuously controlling the air exchange rate at a fixed value with an accuracy of ± 3%.
The supply and
EN 13999-1:2006 (E) 8 exhaust air system shall be designed to ensure proper mixing of the air inside the chamber and to keep the air velocity at the surface of the test specimen in the range from 0,1 m/s to 0,3 m/s. The supply air shall be very clean and pre-filtered, not containing any volatile compounds at a level higher than the required test chamber background concentrations of 10 µg/m3 (total VOC) and 2 µg/m3 for any single component. The control of background concentration shall be carried out with the empty support (5.1) inside the test chamber. NOTE
A four-step filter is suggested: a)
filtration membrane particle size (maximum 0,5 mg/m3 breakthrough); b)
activated charcoal (maximum 0,003 mg/m3 breakthrough); c)
high efficiency compressed air dryer (dew point -40 °C at least) ; d)
high filtration grade (< 0,5 mg/m³ particles breakthrough at 21 °C). 5.5 Air sampling devices The sampling devices as described in Parts 2, 3 and 4 of this European Standard shall take the sample air directly from the exhaust air. The devices shall be connected as close as possible to the test chamber and maintain the same temperature. The sum of sampling air flows shall be smaller than the supply air flow to the emission test chamber. NOTE Placing the whole apparatus in a room conditioned at (23 ± 2) °C is recommended.
5.6 Devices for desorption and analysis Devices for desorption and analysis shall be used as described in Parts 2, 3 and 4 of this European Standard. 6 Adhesive sample 6.1 General Take the adhesive sample to be tested in accordance with EN ISO 15605. Examine and prepare this sample for testing in accordance with EN 1067. 6.2 Pre-conditioning Pre-conditioning of the adhesive sample at an operation temperature of (23 ± 2) °C shall be performed at least 24 h before the test is started. To avoid loss of material, the adhesive sample shall be kept in a sealed container. 6.3 Preparation of a test specimen Test specimens shall be prepared not later than 8 weeks after the manufacture of the adhesive sample.
