Soil quality. Determination of soil microbial biomass - Fumigation-extraction method Ingestion-build-279162 Measurement of electrical surface resistance

Measurement of electrical surface resistance of conductive layers for aerospace applications is extremely important

An eCall equipment mounted on P2WVs is also subjected to far harsher environmental exposure than its in-car counterparts

including wavelength selective switches (WSSs)

PD CEN/TS 17363  on eCall optional additional data in ITS system is useful for:

Soil quality. Determination of soil microbial biomass - Fumigation-extraction method Ingestion-build-279162 Measurement of electrical surface resistance1 Scope This part of ISO 14240 specifies a method for the estimation of microbial biomass of soils by measurement of total extractable organic biomass material mainly from freshly killed microorganisms. The method is also applicable to the estimation of microbial nitrogen and microbial ninhydrin reactive nitrogen in soil, but this part of ISO 14240 describes only the measurement of extractable organic carbon. The fumigation extraction (FE) method is
