Water quality — Interlaboratory comparisons for proficiency testing of analytical chemistry laborato...
ISO/TS 20612:2007 specifies the criteria related to proficiency testing by interlaboratory comparisons in the field of water, waste water and sludge analysis. In particular, it specifies the requirements in respect to proficiency test providers and to the design, execution and evaluation of laboratory proficiency comparisons.
ISO/TS 20612:2007 may be used if the determinands in the…
Water quality — Biochemical and physiological measurements on fish — Part 1: Sampling of fish, handl...
ISO 23893-1:2007 provides guidance on how to sample fish for determination of biochemical and physiological characteristics, such as the composition and enzyme activities of blood, liver, muscle and other tissues in order to asses the health of fish in the field as well as in the laboratory. The biochemical and physiological variables used for this purpose are often called biomarkers.
ISO 23893-1…
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…
