1. Measurement of formaldehyde released to indoor air from articlesreferred to in paragraph 1, first subparagraph, of entry [xx]
1.1 Reference conditions
The formaldehyde released from articles referred to in paragraph 1,first subparagraph of entry [xx] shall be measured in the air of a testchamber under the following reference conditions:
(a) the temperature in the test chamber shall be (23 ± 0,5) ⁰C;
(b) the relative humidity in the test chamber shall be (45 ± 3) %;
(c) the loading factor, expressed as the ratio of the total surface areaof the test piece to the volume of the test chamber, shall be (1 ± 0,02)m2/m3; in cases where such a loading factor is clearly not realisticunder reasonably foreseeable conditions of use, loading factors inaccordance with Section 4.2.2 of EN 165161 may be used;
(d) the air exchange rate in the test chamber shall be (1 ± 0,05)h-1;
(e) an appropriate analytical procedure, to measure the formaldehydeconcentration in the test chamber shall be used;
(f) an appropriate method for sampling of the test pieces shall be used;
(g) the formaldehyde concentration in the air of the test chamber shallbe measured at least twice per day throughout the test with a timeinterval between two consecutive samplings of 3 hours at a minimum; themeasurement shall be repeated until sufficient data are available todetermine the steady state concentration;
(h) the duration of the test shall be sufficiently long to allow thedetermination of the steady state concentration and shall not exceed 28days;
(i) the steady state concentration of formaldehyde measured in the testchamber shall be used to verify the compliance with the limit value offormaldehyde released from articles referred to in paragraph 1, firstsubparagraph, of entry [xx].
Formaldehyde released from articles referred to in paragraph 1, firstsubparagraph, of entry xx] may also be measured in the air of a testchamber under the reference conditions that are more stringent than theones listed in the first paragraph of this point; higher temperatureand/or higher relative humidity and/or higher loading factor and/orlower air exchange rate shall be considered to be more stringentconditions.
1.2. Non-reference conditions
If data from a test method using the reference conditions specified inSection 1.1 are not available, data obtained from a test method usingnon-reference conditions may be used, where there is a correlationbetween the results of the test method used and the reference conditionsspecified in Section 1.1.
Suppliers of articles may, where applicable, apply existing correlationsto the specific articles and test methods considered, to calculate theformaldehyde releases under the reference conditions specified inSection 1.1 in order to demonstrate compliance with paragraph 1, firstsubparagraph, of entry [xx].
If relevant correlation data are not available, they may be generated ona case-by-case basis. Correlation data may be generated, by performingmeasurements of formaldehyde released from articles or samples ofarticles using a method with non-reference conditions and, in parallel,to measure the formaldehyde released from samples of the same articlesunder the reference conditions specified in Section 1.1. Sufficientrepeat testing shall be conducted to ensure the reliability of suchderived correlation.
Where a correlation is evident, it shall only be necessary to undertakethe testing to verify the compliance with the limit value offormaldehyde using the method with non-reference conditions. Parallelmeasurements shall only need to be repeated in case of variations in thecharacteristics of the article, such as material, size, and productionprocess, that may foreseeably affect the release of formaldehyde.
2. Measurement of formaldehyde concentration in the interior ofvehicles referred to in paragraph 2, first subparagraph, of entry [xx]
For road vehicles, including trucks and buses, the formaldehydeconcentration shall be measured in accordance with the conditionsspecified in ISO 12219-12, ISO 12219-103 or anequivalent method, and the concentration measured shall be used toverify the compliance with the limit value referred to in paragraph 2,first subparagraph, of entry [xx].
