ISO/IEC 17025:2017 specifies the general requirements for the competence, impartiality and consistent operation of laboratories.
ISO/IEC 17025:2017 is applicable to all organizations performing laboratory activities, regardless of the number of personnel.
Laboratory customers, regulatory authorities, organizations and schemes using peer-assessment, accreditation bodies, and others use ISO/IEC 17025:2017 in confirming or recognizing the competence of laboratories.

ISO 10382:2002 specifies a method for quantitative determination of seven polychlorinated biphenyls and seventeen organochlorine pesticides in soil. ISO 10382:2002 is applicable to all types of soil. Under the conditions specified in ISO 10382:2002, limits of detection of 0,1 micrograms per kilogram to 4 micrograms per kilogram (expressed as dry matter) can be achieved.

Specifies two methods for the quantitative determination of mineral oil content in soil by IR spectrometry (method A) and gas chromatography (method B). Method A is applicable to mineral oil contents above 20 mg/kg on a dry matter basis, method B to those above 100 mg/kg. Petrol cannot be determined quantitatively with these methods, due to loss of volatile compounds during sample pretreatment. Weak polar compounds of recent biogenic origin may be determined as mineral oil. Relatively high contents of polar compounds give interferences in the determination. Halogenated hydrocarbons also may interfere.
