This document provides guidelines for the use of hydrogen in its gaseous and liquid forms as well as its storage in either of these or other forms (hydrides). This document identifies the basic safety concerns, hazards and risks, and describes the properties of hydrogen that are relevant to safety. Detailed safety requirements associated with specific hydrogen applications are treated in separate International Standards. “Hydrogen” in this document means protium (the most common isotope of hydrogen) (1H2), not deuterium (2H2) or tritium (3H2).

This document specifies a method for the determination of the content of cadmium, chromium, copper, lead, nickel and zinc in fertilizers and liming materials using inductively coupled plasma-atomic emission spectrometry (ICP-AES) after aqua regia dissolution. Limits of quantification are dependent on the sample matrix as well as on the instrument, but can roughly be expected to be 0,3 mg/kg for Cd and 1 mg/kg for Cr, Cu, Ni, Pb and Zn.
This document is applicable to the fertilizing products 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: inorganic fertilizers and liming materials is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic fertilizers and liming materials 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.
NOTE 1 The term fertilizer is used throughout this document and needs to be taken to include liming materials unless otherwise indicated.
NOTE 2 Dissolution by aqua regia is equivalent to digestion and extract and digest are equivalent terms in this sense for the purposes of this standard.

This document specifies methods for measuring rolling resistance, under controlled laboratory conditions, for new pneumatic tyres designed primarily for use on passenger cars, trucks and buses. This document is not applicable to tyres intended for temporary use only. It includes a method for correlating measurement results to allow inter-laboratory comparisons. It is designed to facilitate international cooperation and, possibly, regulation building. Measurement of tyres using the methods of this standard enables comparisons to be made between the rolling resistance of new test tyres when they are free-rolling straight ahead, in a position perpendicular to the drum outer surface, and in steady-state conditions. During the measurement of rolling resistance using the methods of this standard, the value of the rolling circumference of the tyre can be derived using the drum method of either standard ISO 9112 or ISO 17269.

This document specifies a test method for the determination of the specific migration of polycyclic aromatic hydrocarbons (PAH) from paper, board and pulp into the food simulant isooctane. The amounts of polycyclic aromatic hydrocarbons (PAHs) are expressed in micrograms PAH per litre of solvent extract.
It is applicable for the determination of the 24 PAHs given in 6.3, Table 1. The test method is also applicable for the determination of further PAHs unless a validation for every further analyte is done by the laboratory using this test method.
In general, this test method is applicable to the determination of PAHs in concentrations ranging from 2,5 µg/l to 100 µg/l for solvent extracts. Deviations from this range are possible.

This International Standard specifies methods for measuring rolling resistance, under controlled laboratory conditions, for new pneumatic tyres designed primarily for use on motorcycles. The relationship between values obtained and the fuel economy of the vehicle is undetermined, and such values are not intended to be used to indicate levels of performance or quality. This International Standard applies to motorcycle tyres. Measurement of tyres using the methods of this standard enables comparisons to be made between the rolling resistance of new tyres when they are free-rolling straight ahead, in a position perpendicular to the drum outer surface, and in steady-state conditions. In measuring tyre rolling resistance, it is necessary to measure small forces in the presence of much larger forces. It is, therefore, essential that equipment and instrumentation of appropriate accuracy be used. During the measurement of rolling resistance using the methods of this standard, the value of the rolling circumference of the tyre can be derived using the drum method standard ISO 13328.

a) for assessing the compliance of adhesives according to EN 301, EN 15425, EN 16254, EN 17334 and EN 17418;
b) for assessing the suitability and quality of adhesives for load-bearing timber structures;
c) for assessing the effect on the bond strength resulting from constant load at different climate conditions.
This method is intended primarily to obtain performance data for the classification of adhesives for load bearing timber structures according to their suitability for use in defined climatic environments.
