Method for the assessment of the degree of pigment or carbon black dispersion in polyolefin pipes, f...
This International Standard describes a method with two procedures for the assessment of pigment or carbon black
particle and agglomerate size and degree of dispersion in polyolefin pipes, fittings and compounds.
The method is applicable to polyolefin pipes and fittings, as well as raw material in pellet form, with the choice of
procedure to be determined by the referring specification.

Environmental solid matrices — Determination of the specific electrical conductivity
Specifies an instrumental method for the routine determination of the specific electrical conductivity in an aqueous extract of soil. The determination is carried out to obtain an indication of the content of water-soluble electrolytes in a soil.
Green coffee — Determination of loss in mass at 105 °C
ISO 6673 specifies a method for the determination of the loss in mass at 105 °C of green coffee.
It is applicable to decaffeinated and non-decaffeinated green coffee as defined in ISO 3509.
This method of determining the loss in mass can be considered, by convention, as a method for determining the water content and can be used as such by agreement between the interested parties, but it gives…
ISO 15238:2016 specifies a procedure for the determination of the total cadmium content of coal.
This procedure has not been validated with coals that spontaneously ignite. Prior to use with such sample types, users should validate the method.
Coal and coke — Determination of phosphorus — Reduced molybdophosphate photometric method
ISO 622:2016 specifies a reduced molybdophosphate photometric method for the determination of the total phosphorus content of hard coal, lignites and coke. Two methods for taking the phosphorus into solution are specified, namely extraction from the coal or coke ash with acid or by repeated oxidation of the coal or coke, by acid, to remove carbonaceous matter.
Brown coals and lignites — Determination of moisture — Part 2: Indirect gravimetric method for moist...
ISO 5068-2:2007 specifies a method for the determination of the moisture content in the analysis sample of brown coals and lignites using an indirect gravimetric method.
Brown coals and lignites — Determination of moisture — Part 1: Indirect gravimetric method for total...
ISO 5068-1:2007 specifies two methods for determination of the total moisture content of brown coals and lignites using an indirect gravimetric single-stage method and a two-stage method.
Biodiversity – Requirements and guidelines for strategically and operationally addressing biodiversi...
This standard defines requirements and guidelines to help organisations understanding and mainstreaming biodiversity’s protection, conservation, the sustainable use of its components and the fair and equitable sharing of the benefits arising out of the utilization of genetic resources, within their activities.
This standard is suitable for all kind of organisations (e.g. economic operators,…
