This document specifies procedures to determine the thermal resistance of products whose thicknesses exceed the maximum thickness for guarded hot plate or heat flow meter apparatus. Most of the procedures described in this standard require apparatus that allows tests on specimens up to 100 mm thick . This document gives guidelines to assess the relevance of the thickness effect, i.e. to establish whether the thermal resistance of a thick product can or cannot be calculated as the sum of the thermal resistances of slices cut from the product, these guidelines complement the indications given in ISO 8302:1991[1] on the guarded hot plate apparatus. This document describes testing conditions which prevent the onset of convection which could take place in some products under the considered temperature differences and thicknesses.

 

This document describes a method for evaluating the carbonation resistance of concrete using test conditions that accelerate carbonation. After a defined period of curing and a period of preconditioning, the test is carried out under controlled exposure conditions using an increased level of carbon dioxide. NOTE The test performed under reference conditions takes a minimum of 112 days comprising a minimum age of the specimen prior to curing under water of 28 days, a minimum preconditioning period of 14 days and an exposure period to increased carbon dioxide level of 70 days. This procedure is not a method for the determination of carbonation depths in existing concrete structures.

 

This document describes a method for determining the unidirectional apparent chloride diffusion coefficient and surface concentration of conditioned specimens of hardened concrete. The test method enables the determination of the chloride penetration after a specified length of curing and length of exposure to NaCl solution. Since resistance to chloride penetration depends on ageing which includes the effects of continual hydration and interactions with the chloride solution, then the apparent diffusion coefficient also changes with age. A procedure to determine this ageing, expressed here by an ageing exponent, is included in this document and described in Annex A. The test procedure does not apply to concrete with surface treatments such as silanes and it does not apply to concrete containing fibres (see E.1).

 

This document specifies a method of determining the carbonation rate of a concrete, expressed in mm/va. This document establishes a procedure where a standardized climate controlled chamber is used and where specimens are placed on a natural exposure site protected from direct rainfall. The standardized climate controlled chamber procedure is the reference method. These procedures are applicable for the initial testing of concrete, including those manufactured with slowly reacting binders, provided that the ages at which the carbonation depth is measured, the number of measurements required to calculate the carbonation rate, as well as the length of exposure to CO2, are appropriately selected, as described in this document. These procedures are not applicable for factory production control.

 

This document specifies a method for the digestion of soil improvers and growing media using an aqua regia digestion. Materials containing more than about 28 % (m/m) organic matter will require treatment with additional nitric acid. With high solute concentrations in extract solutions, spectral interferences and background enhancement should be expected.

 

This document specifies different methods for quantitative determination of 16 polycyclic aromatic hydrocarbons (PAH) (see Table 1) in compost or digestate, using GC-MS, GCMS/MS or HPLC UV DAD/FLD covering a wide range of PAH contamination levels (see Table 1). When using fluorescence detection, acenaphthylene cannot be measured. Table 1 — Target analytes of this document [...table not reproduced...] The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract. This document contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used. The method may be applied to the analysis of other PAH not specified in the scope, provided suitability is proven by proper in-house validation experiments.

 

This document specifies a method for the extraction and determination of phosphonates (P-PO3) in growing media and soil improvers using ion chromatography and conductivity detection (IC-CD). This document is applicable to the fertilizing product blends where a blend is a mix of two or more fertilising products belonging to the categories of fertilizers, liming material, soil improvers, growing media, inhibitors and plant biostimulants, and where soil improvers and/or growing media are the components with the highest percentage in the blend by mass or volume, or in the case of products in liquid form by dry mass. If the soil improvers and/or growing media are not the components with the highest percentage in the blend, the document relevant to the component with the highest percentage in the blend applies. In case a blend is composed of fertilising products mixed in equal quantities, the user of the document decides which standard to apply. NOTE A soil improver consists of a single bulky (volume-building) component or a mix of bulky (volume-building) components (for example peat, wood fibres, coconut coir, compost, expanded perlite).

 

This document specifies a method for the determination of the dimensions, volume and the bulk density of pre-shaped and non pre-shaped plugs.

 

This document specifies a method for the determination of the chloride (Cl-) content by potentiometric titration. This method is applicable to growing media and soil improvers. NOTE It is possible to use other analytical techniques (e.g. ion chromatography, discrete analyser, continuous flow analyser); in this case a validation is carried out by the laboratory for the procedure and data generated.

 

This International Standard describes the procedure to qualitatively detect genetically modified organisms (GMOs) and derived products by analysing the nucleic acids extracted from the sample under study. The main focus is on polymerase chain reaction (PCR) based amplification methods. It gives general requirements for the specific detection and identification of target nucleic acid sequences (DNA) and for the confirmation of the identity of the amplified DNA sequence. Guidelines, minimum requirements and performance criteria laid down in this International Standard are intended to ensure that comparable, accurate and reproducible results are obtained in different laboratories. This International Standard has been established for food matrices, but could also be applied to other matrices (e.g. feed and plant samples from the environment). Specific examples of methods are provided in Annexes A to D.

A citizen science diver is competent in basic underwater scientific methodologies and protocols and shall be able to assist in scientific diving activities. This standard will specify competencies, prerequisites for training, Introductory information, Required theoretical knowledge, Required practical skills, Practical training parameters and Evaluation criteria for training systems aimed at training citizen science divers.

 

This document specifies the terms and definitions related to the structures for mine shafts, used throughout ISO 19426. Terms used in mining can vary from conventional engineering usage, and they vary quite considerably between different countries. For this reason, alternative terms are provided in many of the entries. The preferred terms, given in bold type, are those used throughout ISO 19426. It is assumed that users of this document are familiar with mining, so common terms with normal dictionary usage are not defined. Also, no definitions are provided for terms that can be widely used in mining but are not explicitly used in ISO 19426.

This document specifies conditions for the determination of circumferential mechanical properties of ceramic matrix composite (CMC) tubes with continuous fibre-reinforcement at room temperature on C-ring specimen under diametric compression. This document is specific to the tubular geometries because fibre architecture and specimen geometry factors in composite tubes are distinctly different from those in flat specimens. This test method is straightforward to carry out and low-material consumption. It provides information on the circumferential Young modulus, the mechanical response and the ultimate fracture force. If the ultimate fracture occurs within the linear elastic domain, then the compressive strength can be determined from the corresponding ultimate fracture force. The information can be used for material development, control of manufacturing (quality insurance), material comparison, characterization, reliability and design data generation for tubular components. This document addresses, but is not restricted to, various suggested test piece fabrication methods. This document is primarily applicable to ceramic matrix composites tube with a continuous fibrous-reinforcement: unidirectional (1D, filament winding and tape lay-up), bidirectional (2D, braid and weave) and multi-directional (xD, with x >2).
