Soil quality. Determination of content of hydrocarbon in the range C₁₀ to C₄₀ by gas chromatography1 Scope This International Standard specifies a method for the quantitative determination of the mineral oil (hydrocarbon) content in field moist soil samples by gas chromatography. The method is applicable to mineral oil contents (mass fraction) between 100 mg kg and 10 000 mg kg soil, expressed as dry matter, and can be adapted to lower limits of detection. This International Standard is applicable to the determination of all hydrocarbons with a

The requirements for passenger conveyors are based on the use of two distinct types of treadway:

linear low-density polyethylene or a copolymer in which ethylene is the major constituent

which has been developed to support IEC 61340‑5‑1

Determination of consistence retentivity and water retentivity-

ISO 8126 specifies visual diffuse transmission densities for second-generation silver-gelatin and diazo microforms and projection densities for second-generation vesicular microforms

At the present stage of technology this requirement is best met by adopting the equivalent continuous A-weighted sound pressure level as a basic quantity

Note: ISO/IEC TR 10037 does not specify a “standard editing system”

This European Standard is applicable to connectors used:

The objective of ISO/TR 17427 is to raise awareness of and consideration of such issues

This part of ISO 17185 does not standardize specific information interfaces such as data format or a stop point numbering system and so on but currently available regional standards established by regional and national groups are suggested to be applied

users can determine the soluble nitrogen in animal feeds that enables the digestion of proteins found in ingested food for effective health

are relative values associated with the specific test method used and the magnification used during examination
