This document sets out a laboratory sequential procedure for the froth flotation testing of fine coal, e.g. coal having a particle size of less than 0,5 mm. The procedure provides a means of evaluating the flotation characteristics for coal (expressed as a yield/ash relationship) that can be expected from the froth flotation process. This document does not apply to pulp samples that cannot be…

This document specifies two procedures for the in situ determination of the insertion loss of underwater noise abatement measures (noise abatement systems). The impulsive sound of pile driving is used as the sound source for the investigation of noise abatement systems. This document does not apply to artificial sound sources and investigations under laboratory conditions. Apart from the correct…

This document specifies the general requirements for the in vitro amplification of nucleic acid sequences (DNA or RNA). This document is applicable to the testing for microorganisms and viruses from the food chain using the polymerase chain reaction (PCR). This document, or parts of it, is applicable to other fields of PCR diagnostics based on a case-by-case evaluation. The minimum requirements…

This document specifies a laboratory test method for evaluating the thermal stress resistance of water-leakage crack repair materials through permeability testing. This document outlines general principles and procedures for the test method. This document does not specify specific variables that control the quantifiable parameters of the testing.

This document specifies a laboratory test method for evaluating the substrate (crack) movement response of water-leakage crack repair materials through permeability testing. This document outlines general principles and procedures for the test method. Specific variables that control the quantifiable parameters of the testing are filled in using relevant national standards or testing parameters,…

This document specifies a laboratory test method for evaluating watertightness of water-leakage crack repair materials through permeability testing. This document outlines general principles and procedures for the test method. This document does not specify specific variables that control the quantifiable parameters of the testing.

This document deals with the likely degradation of air performance of fans tested in standardized airways according to ISO 5801 when compared with the performance of fans tested under actual site conditions. It deals with the performance of a number of generic types of fan and fittings. The results given are intended as guidelines and only provide trends, as the system effect depends on the exact…

This document specifies a method for the determination of β-galactooligosaccharides (GOS) in infant formula (both powder and liquid) containing 0,2 g/100 g to 3,0 g/100 g of GOS in the product as prepared ready for consumption. The method has been validated in a multi-laboratory study with reconstituted infant formula at levels of 0,236 g/100 g, 0,594 g/100 g, 0,616 g/100 g and 0,688 g/100 g and…

This document specifies a method for the generation of tyre and road wear particles (TRWP) in a road simulator laboratory that is representative of actual driving conditions. Guidance is provided for the road simulator system, test pavement and tyres, vacuum collection system, monitoring and reporting. This method is applicable for the collection of TRWP from a known pavement and tyre type under…
