This document specifies a laboratory method for the extraction of microplastics from compost matrices originating from industrial or home composting. The method outlines various extraction steps assuring polymer stability, and high recovery rate. This extraction process separates microplastics from the compost matrix that can be further analysed either by number-based or by mass-based techniques.

The method is applicable for microplastics up to 1 mm in size.

The method is applicable for microplastics with densities lower than 1,4 g/cm3.

This document will not specify downstream detection methods for the identification and quantification.

The method in this document has not been validated for microplastic extraction from other matrices, except for composts.

This document defines methods that measure amounts of bacterial cells or a marker gene DNA to obtain the total abundance in environmental aqueous samples, such as seawater and river water, for biodegradability assessment. Amounts of a marker gene DNA enable to give a prediction of abundance of bacterial cells by using a conversion factor such as average number of the marker gene homologues in a bacterial cell. The methods could be also applicable to aqueous samples artificially enriched with bacterial cells released from environmental sediments. In addition, this document is applicable to solution with bacteria extracted from environmental sediments and plastic surfaces, where appropriate pre-treatment might be defined elsewhere. In the document, the method provides measurement of prokaryotic bacterial cells, though eukaryotic microorganisms are out of scope.

NOTE   Eukaryotic microorganisms, especially fungi, are well known to be primary decomposers in land, but the role in hydrosphere has been less documented and is largely unknown yet. Actually, the proportion of fungi in the ocean whole microbial metagenome has been reported as low (fungal reads make up 1,4 % to 2,9 % [2]).

This document specifies a method for extraction, separation, and determination of inorganic arsenic (iAs) in organic or organo-mineral fertilizers using anion-exchange high performance liquid chromatography (HPLC) or ion chromatography (IC) coupled to ICP-MS. This document is applicable to fertilizing product blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants and where the following category organic fertilizer or organo-mineral fertiliser is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If the organic fertilizer or the organo-mineral fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.

This document specifies methods used to determine the concentration of plutonium and neptunium isotopes in water by inductively coupled plasma mass spectrometry (ICP-MS) (239Pu, 240Pu, 241Pu and 237Np). The concentrations obtained can be converted into activity concentrations of the different isotopes[9]. Due to its relatively short half-life and 238U isobaric interference, 238Pu can hardly be measured by this method. To quantify this isotope, other techniques can be used (ICP-MS with collision-reaction cell, ICP-MS/MS with collision-reaction cell or chemical separation). Alpha spectrometry measurement, as described in ISO 13167[10], is currently used[11]. This method is applicable to all types of water having a saline load less than 1 g·l−1. A dilution of the sample is possible to obtain a solution having a saline load and activity concentrations compatible with the preparation and the measurement assembly. A filtration at 0,45 μm is needed for determination of dissolved nuclides. Acidification and chemical separation of the sample are always needed. The limit of quantification depends on the chemical separation and the performance of the measurement device. This method covers the measurement of those isotopes in water in activity concentrations between around[12][13]: — 1 mBq·l−1 to 5 Bq·l−1 for 239Pu, 240Pu and 237Np; — 1 Bq·l−1 to 5 Bq·l−1 for 241Pu. In both cases, samples with higher activity concentrations than 5 Bq·l−1 can be measured if a dilution is performed before the chemical separation. It is possible to measure 241Pu following a pre-concentration step of at least 1 000.

This document specifies methods for testing the resistance to sustained longitudinal tensile loading (longitudinal stress-rupture) of uniaxial plastic pipe/pipe or pipe/fitting or fitting/fitting assemblies using hydrostatic pressure at a given temperature. This document is applicable to pipe assemblies with electrofusion or butt fusion joints. The methods accommodate water-in-water, water-in-air, and liquid-in liquid tests. Method A uses no external hoop expansion restraint (specifically designed test piece). Method B uses external hoop expansion restraint (metal end caps or circumferential (ring) clamps). Note 1 The longitudinal (axial) tensile loading by hydrostatic internal pressure is achieved by using means to create axial stress as the maximum principal stress over the hoop stress in the assemblies. The external hoop expansion restraint or specific test piece design is used for this purpose[1,2].

This document establishes a system for the classification of fan efficiency for all fan types driven by motors with an electrical input power of 0,125 kW and above. It applies to driven fans only, but not to the system (finished original equipment manufacturer’s product, for example box fans and roof fans or ventilation system) in which they might be installed. This document, as well as ISO 12759-3, ISO 12759-5 and ISO 12759-6, describe a number of different procedures to classify the efficiency of a fan or to apply a minimum efficiency limit (MEL).

Appendix F shows how procedures described in this document can be used to set MELs.

There is no method described to compare these classifications and MELs.
