Despite numerous methods developed and in use, there is, presently, still no universal method by means by which the quantity of free formaldehyde release in wood products can be established with certainty. In the various countries, various standardised methods are in use. The correlations among some of them are still unknown. In the article we determined the content of released free formaldehyde in particleboards according to the perforator method with the objective to determine the correlation between the iodimetric titration and acetylacetone method. Becausethe quantity of released formaldehyde is also affected by the structureof the material, we also tried to establish the influence of the composition of a chipboard on the quantity of released formaldehyde. The correlation between the iodimetric titration and acetylacetone method is good (R2 = 0.8265). The composition of a chipboard (where we limited ourselves to the ratio between the middle and external layers of the particleboard) has influence on the quantity of released formaldehyde"},{"@xml:lang":"sl","#text":"Količina prostega formaldehida v lesnih proizvodih je kljub nizkim vrednostim še vedno predmet stalnega nadzora in tudi predmet novih raziskav. Kljub številnim razvitim in tudi uporabljenim metodam danes še ne obstaja univerzalna metoda, s katero bi z največjo zanesljivostjo ugotovili količino vsebovanega prostega formaldehida v lesnih proizvodih. V različnih deželah so uporabljajo različne standardizirane metode. Korelacije med nekaterimi od njih še niso znane. V prispevku smo ugotavljali vsebnost postega formaldehida v ivernih ploščah po perforatorski metodi, s ciljem določitve korelacije med jodometrično titracijo in acetilacetonsko metodo. Ker na količino spoščenega prostega formaldehida vpliva tudi struktura materiala, smo ugotavljali tudi vpliv sestave iverne plošče na količino oddanega formaldehida. Korelacija med jodometrično titracijo in acetilacetonsko metodo je dobra (R2= 0,8265).
