Annex
Cabinet Regulation No. 301
19 April 2011

Methods of Sampling and Analysis

I. Methods of Sampling and Analysis of Asbestos Emission into Water

1. Reference method:

1.1. the reference method shall be filtering through a 0.45 μm filter membrane, followed by drying at a temperature of 105 °C and weighing. Results shall be expressed as mg/l. By utilising the reference method, the total amount of suspended matter (filterable matter from a non-precipitated sample) shall be determined;

1.2. samples shall represent emission over a 24 hour time period;

1.3. the precision of results shall be ±5 % and reproducibility shall be ±10 %.

II. Methods of Sampling and Analysis of Emission into the Air

2. Gravimetric method:

2.1. with the gravimetric method, it is possible to measure the total amount of solid particles emitted through the discharge ducts;

2.2. if measurements of concentration are necessary, the concentration of asbestos in solid particles shall be measured or evaluated;

2.3. sampling shall be conducted before any dilution of the flow to be measured;

2.4. in order to check the conformity to the limit value of emission, at least two measurements shall be taken under the same isokinetic conditions. The results of measurements may not differ for more than 20%;

2.5. sampling shall be conducted under such operating conditions which in accordance with technical documentation of the equipment comply with normal operating conditions of the equipment;

2.6. sampling shall be conducted at a place with an even flow of air. If possible, the person taking samples shall prevent turbulence and remove obstacles that might disrupt the flow of air;

2.7. in air ducts where samples are taken, adequate apertures and platforms shall be provided;

2.8. before the commencement of sampling, air temperature and pressure as well as the flow rate in the air duct shall be measured. Air temperature and pressure shall normally be measured along the sampling line at a normal flow rate. If necessary, water vapour concentration shall also be measured so that the results can be amended accordingly;

2.9. when taking a sample of air from an air duct carrying asbestos dust, the asbestos content in solid particles retained in the filter shall be filtered and measured:

2.9.1. the sampling tube shall first be checked to ensure that it is airtight and there are no leaks that might cause measurement errors. The head of the sampler shall be carefully sealed and the sampler pump started up. The rate of leakage shall not exceed 1% of normal sample flow;

2.9.2. sampling shall be conducted under isokinetic conditions;

2.9.3. the duration of sampling shall depend on the type of process being monitored and on the sampling tube utilised, but the duration of sampling shall be sufficient to ensure collection of the necessary quantity of matter;

2.9.4. if the sampler filter is not in the immediate proximity of the sampler head, the matter precipitated in the probe shall be collected;

2.9.5. the sampler head and number of places for sampling shall be determined in accordance with the Latvian National Standard LVS ISO 9096 "Stationary source emissions - Manual determination of mass concentration of particulate matter";

2.10. a sampler filter appropriate to the technique of analysis shall be chosen. For the gravimetric method, only glass fibre filters shall be utilised. Filtration efficiency shall be at least 99 % and it shall be determined by utilising the DOP test with an aerosol that creates particles of 0.3 μm in diameter;

2.11. an appropriate balance of high precision shall be utilised. In order to ensure accurate results, filters shall be carefully conditioned before and after the sampling;

2.12. temperature, pressure and air flow, dimensions of air ducts, volumes sampled, and also the method of calculation utilised to obtain the results shall be recorded for each sample. Results shall be expressed in conformity with a normal temperature (273 K) and normal pressure (101.3 kPa).

3. A method for fibre counting:

3.1. if the fibre counting method is utilised for the purpose of checking the conformity of emission to the limit value specified in Paragraph 6 of this Regulation, a conversion factor shall be utilised - two fibres per millilitre equals 0.1 mg/m3 asbestos dust;

3.2. asbestos fibre is a fibre which is more than three micrometers in breadth and more than five micrometers in length and having a length-to-breadth ratio of more than 3:1 and which is counted by phase contrast optical microscope utilising a fibre-counting method in conformity with the laws and regulations regarding labour protection requirements in work with asbestos;

3.3. a fibre-counting method shall be chosen that enables measuring of fibre concentration in exhaust gases;

3.4. sampling shall be conducted before any dilution of the flow to be measured;

3.5. sampling shall be conducted under such operating conditions which in accordance with technical documentation of the equipment comply with normal operating conditions of the equipment;

3.6. sampling shall be conducted at a place with an even flow of air. If possible, the person taking samples shall prevent turbulence and remove obstacles that might disrupt the flow of air;

3.7. in air ducts where samples are taken adequate apertures and platforms shall be provided;

3.8. before the commencement of sampling, air temperature and pressure as well as the flow rate in the air duct shall be measured. Air temperature and pressure shall normally be measured along the sampling line at a normal flow rate. If necessary, water vapour concentration shall also be measured so that the results can be amended accordingly;

3.9. when taking a sample of air from an air duct carrying asbestos dust, the asbestos content in solid particles retained in the filter shall be filtered and measured:

3.9.1. the sampling tube shall first be checked to ensure that it is airtight and there are no leaks that have caused measurement errors. The head of the sampler shall be carefully sealed and the sampler pump started up. The rate of leakage shall not exceed 1% of normal sample flow;

3.9.2. sampling shall be conducted inside the emission duct under isokinetic conditions;

3.9.3. the duration of sampling shall depend on the type of process being monitored and on the sampling nozzle utilised, but the duration of sampling shall be sufficient to ensure that the sample collection filter carries 100-600 countable asbestos fibres per 1 mm2;

3.9.4. the sampler head and number of places for sampling shall be determined in accordance with the Latvian National Standard LVS ISO 9096 "Stationary source emissions - Manual determination of mass concentration of particulate matter";

3.10. a sampler filter that is appropriate to the technique of measurement shall be chosen. For the fibre counting method, membrane filters (with a membrane of mixed esters of cellulose or cellulose nitrates) of nominal pore size 5 μm, with printed squares and 25 mm in diameter shall be used. The sampling filter shall have a filtration efficiency of 99 % with respect to countable asbestos fibres;

3.11. temperature, pressure and air flow, dimensions of air ducts, volumes sampled, as well as the method of calculation utilised to obtain the results shall be recorded for each sample. Results shall be expressed in conformity with a normal temperature (273 K) and normal pressure (101.3 kPa).
