Informative reference to European Union directive rules included provisions deriving from Council of 19 March 1987 the Directive 87/217/EEC on the prevention and reduction of environmental pollution by asbestos. Prime Minister a. Halloween Environment Minister r. vējonis annex Cabinet of 25 April 2006, regulations No 332 methods of sampling and analysis I. Sampling and method of analysis of asbestos emissions into water 1. Reference method: 1.1. reference method is through a 0.45 μm filtering membrane filters followed by drying of the 105 ° C and weighing. Express the results in mg/l with the reference method determines the total quantity of suspended matter (filterable matter from the non precipitated sample);
1.2. the samples must represent the emissions within 24 hours;
1.3. the accuracy of the results must be within ± 5%, the reproducibility must be ± 10%.
II. Methods of sampling and analysis for the emissions of asbestos into the air 2. Gravimetric method: gravimetric method with 2.1 can measure the total quantity of particulate matter emitted through the discharge ducts;
2.2. If necessary, the measurements of the concentration measured or evaluated the concentration of asbestos in the solid particles;
2.3. the samples shall be taken before any dilution of the measured flow;
2.4. in order to verify compliance with the emission limit values, at least two measurements shall be made under the same isokinetic conditions. The results of measurement must not differ by more than 20%;
2.5. sampling equipment in normal operation mode;
2.6. samples shall be taken where there is a steady flow of air. If possible, the worker, as well as preventing water barriers that would stop the air flow;
2.7. air channels that are sampled, generates the appropriate openings and pads;
2.8. before sampling size air temperature and pressure, as well as the flow rate of the air channel. The air temperature and pressure is usually measured along the sampling line, as is the normal flow rate. If necessary, the size of the water vapour concentration so that you can adjust accordingly;

Carefully reseal the sampling nozzle and trigger the sampler pump. Outflow rate does not exceed 1% of the normal sample flow;
3.9.2. samples inside the emission duct under isokinetic conditions;

3.10. the sampling filter of choice that is suitable for the measurement technique. The method of counting fibres using membrane filters (mixed esters of cellulose or cellulose nitrate membranes) with a nominal pore size 5 µm, printed squares and a diameter of 25 mm. Sampling filter has a filtration efficiency of 99% with respect to countable asbestos fibres;
3.11. for each sample record temperature, pressure and air flow, air channel, volume, also checked out the results of the calculation method used. The results shall be expressed in accordance with normal temperature (273 K) and normal pressure (101.3 kPa). Minister for the environment r. vējonis
