If particulate matter is monitored discontinuously, the concentrations should be measured at regular intervals, taking at least three independent readings per check.

Monitoring of either emissions or performance indicators should take place continuously if the emitted mass flow of particulates is above 10 kg/h. If emissions are monitored, the concentrations of air pollutants in gas-carrying ducts have to be measured in a representative fashion.

According to our findings, Tg concentrations were significantly higher in patients with follicular thyroid cancer in contrast to the patients with other forms of thyroid cancer before the removal of the thyroid. the aim of this study was to search for the possibilities of differentiation of malignant from bening thyroid tumors with serum Tg measurements.

It is recommended that the analysers be operated such that the measured concentration falls between 15 % and 100 % of full scale.

The optional gas drying device must have a minimal effect on the concentration of the measured gases.

The Commission may inform one or several Member States that it considers a concentration fulfils the criteria in paragraph 1.

Reference method referred to in Article 7 (1) for the measurement of asbestos in air at the place of work

The average values of the background concentrations can be determined by the sample bag method or by continuous measurement with integration.

Partial flow dilution system with twin venturi or twin orifice, concentration measurement and fractional sampling

If the concentration of one or more of the substances found in the sample is excessive, dilute the sample extract and repeat the measurement.

Concentration in air = (number per graticule area Î exposed area of filter) / (graticule area Î volume of air collected).

If after an adequate period of time the reading shows a lower concentration compared to the introduced concentration, this points to calibration or leakage problems.

The pre-and post test background CO2 or NOx concentration measurements of the dilution air must be within 100 ppm or 5 ppm of each other, respectively.

The analysers shall have a measuring range appropriate for the accuracy required to measure the concentrations of the exhaust gas components (section 3.1.1).

NOx conc, COconc, HCconc(1), NMHCconc= average background corrected concentrations over the cycle from integration (mandatory for NOx and HC) or bag measurement, ppm

workers and/or their representatives in the undertaking or establishment have access to the results of asbestos-in-air concentration measurements and can be given explanations of the significance of those results;

It is the responsibility of the Commission to show that a concentration creates or strengthens market structures which are liable to impede significantly effective competition in the common market.

The Horrat value gives a comparison of the actual precision measured with the precision predicted by the Horwitz equation for a method measuring at that particular level of analyte.

By diluting the standard solution (3.5) with water, prepare at least 5 reference solutions of increasing concentration, corresponding to the optimal measuring range of the spectrophotometer.

Whereas optical microscopy, although it does not allow a counting of the smallest fibres detrimental to health, is the most currently used method for the regular measuring of asbestos;

For systems that use CO2 or NOx concentration measurement for dilution ratio control, the CO2 or NOx content of the dilution air must be measured at the beginning and at the end of each test.

Our results indicate that if current diabetes diagnostic criteria are applied to patients seen in the afternoon, approximately half of all cases of undiagnosed diabetes in these patients will be missed.

The increase in concentration as measured by the HHI can be calculated independently of the overall market concentration by doubling the product of the market shares of the merging firms.

For each Member State, provide sufficient financial or other data to show that the concentration meets or does not meet the relevant jurisdictional criteria under the applicable national competition law.

The hydrochloric acid concentration of this solution must not exceed 0 74 N. Add 10 ml strontium salt solution (3.4) and then make up the volume to 100 ml with water. Measure the absorption of the solution to be determined and of the reference solutions at 285.2 nm.

Where the Commission finds that a notified concentration fulfils the criterion laid down in Article 2(2) and, in the cases referred to in Article 2(4), the criteria laid down in Article 81(3) of the Treaty, it shall issue a decision declaring the concentration compatible with the common market.

For the purposes of measuring asbestos in the air, as referred to in the preceding paragraph, only fibres with a length of more than five micrometres and a length/breadth ratio greater than 3: 1 shall be taken into consideration.

In order to ensure compliance with the limit values laid down in Article 8, the measurement of asbestos in the air at the place of work shall be carried out in accordance with the reference method described in Annex I or any other method giving equivalent results.

The test for compatibility under Article 2(2) and (3) of the Merger Regulation is whether or not a concentration would create or strengthen a dominant position as a result of which effective competition would be significantly impeded in the common market or a substantial part of it (7).

Where the Commission finds that a concentration fulfils the criterion defined in Article 2(3) or, in the cases referred to in Article 2(4), does not fulfil the criteria laid down in Article 81(3) of the Treaty, it shall issue a decision declaring that the concentration is incompatible with the common market.
