10. Fremgangsmåde ifølge et hvilket som helst af kravene 6-9, kendetegnet ved, at pH-værdien overvåges i løbet af trin C og opretholdes ved en værdi mellem 3,0 og 6,0, fortrinsvis mellem 4,2 og 4,7, ved at tilføje en base og/eller en syre.
11. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at reaktionstemperaturen i trin C er på mellem 160 og 190 grader Celsius.
12. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at træet har en temperatur, der er højere end 150 grader Celsius, i mellem 10 og 60 minutter i løbet af trin C.
13. Fremgangsmåde ifølge et hvilket som helst af de foregående krav, kendetegnet ved, at dampen har et tryk på mindst 4 bar i løbet af trin C.
14. Præserveret træprodukt, som kan opnås ifølge fremgangsmåden ifølge et hvilket som helst af de foregående krav.
15. Apparat, som er programmeret til at udføre fremgangsmåden ifølge et hvilket som helst af de foregående krav, hvilket apparat omfatter - et behandlingsrum, som kan forsegles på middeltæt vis, - en vakuumpumpe, som er forbundet med behandlingsrummet, - en dampkilde, som er forbundet med behandlingsrummet, - en opvarmningsindretning, som er i termisk kontakt med behandling srummet, - dispenseringsmiddel til tilføjelse af forudbestemte mængder af en base og/eller en syre til behandlingsrummet, - pH-målemiddel til bestemmelse af pH-værdien af damp i behandlingsrummet, og - måle- og styreudstyr, som er indrettet til at overvåge i det mindste pH-værdien, temperaturen og trykket inde i behandlingsrummet og til at styre vakuumpumpen, dampkilden, varmekilden og pH-værdien ved at dispensere en base og/eller en syre.
