Water quality — Biochemical and physiological measurements on fish — Part 2: Determination of ethoxy...
ISO/TS 23893-2:2007 specifies a method for measuring the ethoxyresorufin-O-deethylase (EROD) enzyme activity on a post-mitochondrial fraction of fish liver homogenate (subcellular fraction in which the EROD activity is located) employing a cell or microplate fluorimetric method.
It applies to fish that are sampled in their natural environment (fresh water or salt water) or exposed to substances…
Radiation protection instrumentation - Equipment for sampling and monitoring radioactive noble gases
Is applicable to equipment used for sampling and continuous measurement of radioactive noble gases in the workplace, in gaseous effluents discharged into the environment as well as in the environment itself. Monitoring by definition is the process of continuous and real-time measurement. The processes of sampling or taking samples for retrospective laboratory analysis are covered as well.
Application of uncertainty of measurement to conformity assessment activities in the electrotechnica...
IEC Guide 115 presents a practical approach to the application of uncertainty of measurement to conformity assessment activities in the electrotechnical sector. It is specifically conceived for use in the IECEE Schemes as well as by testing laboratories engaged in testing electrical products to safety standards. IEC Guide 115 describes the application of uncertainty of measurement principles,…
SCOPE
The product requirements apply to plastic bags made from different types of plastic.
NOTE - The different types of plastic may be, for example, from fossil resources or non-fossil resources.
Plastics - Determination of the degree of disintegration
of plastic materials under defined composting
conditions in a pilot-scale test.
Plastics - Determination of the degree of…
ISO 10650-2:2007 specifies requirements and test methods for powered polymerization activators with light-emitting diodes (LED) in the blue wavelength region intended for chair-side use in polymerization of dental polymer-based restorative materials.
ISO 10650-2:2007 is not applicable to powered polymerization activators used in laboratory fabrication of indirect restorations, veneers, dentures…
Determination of the ultimate aerobic biodegradability of plastic materials under controlled compost...
ISO 14855-2:2007 specifies a method for determining the ultimate aerobic biodegradability of plastic materials under controlled composting conditions by gravimetric measurement of the amount of carbon dioxide evolved. The method is designed to yield an optimum rate of biodegradation by adjusting the humidity, aeration and temperature of the composting vessel.
The method applies to the following…
Soil quality — Guidance on long and short term storage of soil samples
ISO 18512:2007 gives guidance on how to store and preserve soil samples for laboratory determinations and how to prepare them for analysis after storage. Special emphasis is given to maximum storage times as a function of different storage conditions.
