検査方法にあります?STAS 11277/1-79、?SR ISO 10523:1997、?AOAC 973.55
一体これは何を表しているのでしょうか?
教えてください。

?STAS 11277/1-79

これは10-79ではないですか?

とあるので土壌の質に関するISO規格になっているようです。

ISO 11277:1998

Soil quality - Determination of particle size distribution in mineral soil material - Method by sieving and sedimentation

This International Standard specifies a basic method of determining particle size distribution applicable to a wide range of mineral soil materials, including the mineral fraction of organic soils. It also offers procedures to deal with the less common soils mentioned in the introduction. This International Standard has been developed largely for use in the field of environmental science, and its use in geotechnical investigations is something on which professional advice might be required.

A major objective of this International Standard is the determination of enough size fractions to enable the construction of a reliable particle size distribution curve.

This International Standard does not apply to the determination of the particle size distribution of the organic components of soil, i.e. the more or less fragile, partially decomposed, remains of plants and animals. It should also be realized that the chemical pretreatments and mechanical handling stages in this International Standard could cause disintegration of weakly cohesive particles that, from field inspection, might be regarded as primary particles, even though such primary particles could be better described as aggregates. If such disintegration is undesirable, then this International Standard should not be used for the determination of the particle size distribution of such weakly cohesive materials.

ICPA自体はBucharestの組織のようです。

ISO 10523:1994

Water quality - Determination of pH

The method specified (using a pH-meter) is applicable to all types of water and waste water samples in the range from pH 3 to pH 10. The temperature, some gases and organic materials interfere with the pH-measurement. Suspended materials in the sample may cause significant errors. When measuring sewage and some surface waters, there is a particularly high risk of smearing the electrodes or contaminating the membranes and diaphragm with oil, grease or other contaminants.


?AOAC 973.55

1884年に米国内の肥料検査法の統一を目的に設立された団体Association of Official Agricultural Chemistsを起源として、色々な変遷を経て現在正式名称を”AOACインターナショナル”(http://www.aoac.org)と呼ばれる団体です。
