This document specifies a method for determining the film hardness by pushing pencils of known hardness over the film. The test can be performed on a single coating of a paint, varnish or related product, or on the upper layer of a multi-coat system. This rapid test has not been found to be useful in comparing the pencil hardness of different coatings. It is more useful in providing relative ratings for a series of coated panels exhibiting significant differences in pencil hardness. The method is applicable only to smooth surfaces.

 

ISO 15110:2017 specifies a so-called acid dew and fog test (ADF test) as an accelerated laboratory test method for simulating, by the use of artificial acidic precipitation, the damaging effects of acidic atmospheric precipitation in association with UV radiation, neutral condensed precipitation, and changing temperature and humidity. This test method is intended to be used in evaluating, on the basis of relative performance rankings, the suitability of painted materials for use in outdoor environments with acidic precipitation. It is not intended to generate the same extent of damage or the same damage pattern as in outdoor weathering, but rather to give a ranking which is similar to that which would be obtained in outdoor weathering. The method produces damage which is more homogeneous, allows fewer specimens to be exposed (and hence more rapid testing) and enables evaluation of the exposed specimens to be carried out using methods which are more objective than visual assessment.

 

This document applies to acetylene manifold systems extending from the cylinder valve or the bundle outlet connections to the outlet connection of the main shut-off valve.

This part of ISO 16200 gives general guidance for the sampling and analysis of volatile organic compounds (VOCs) in air by solvent desorption/gas chromatography using pumped sampling. This part of ISO 16200 is applicable to a wide range of VOCs, including hydrocarbons, halogenated hydrocarbons, esters, glycol ethers, ketones and alcohols. A number of sorbents are recommended for the sampling of these VOCs, each sorbent having a different range of applicability. However, activated coconut shell charcoal is frequently used. Very polar compounds may require derivatization; very low boiling compounds may only be partially retained by the sorbents and can only be estimated qualitatively. Semi-volatile compounds should be fully retained by the sorbents, but may only be partially recovered. The upper limit of the useful range is set by the sorptive capacity of the sorbent used and by the linear dynamic range of the analytical instrumentation used. The lower limit of the useful range depends on the type of detector used, on the noise level of the detector and on blank levels of analyte and/or interfering artefacts on the sorbent tubes or in the desorption solvent. Artefacts are typically sub-nanogram for activated charcoal, but higher levels of aromatic hydrocarbons have been noted in some batches. By applying this part of ISO 16200, the lower limits achieved are typically in the range of 1 µg to 100 µg of a given VOC per sample. The concentration range for which this part of ISO 16200 is valid for the measurement of airborne vapours of VOCs is dependent on the lower limit and on the volume sampled. For example, for a 10-litre sample of air, the range is approximately 0,1 mg/m3 to 100 mg/m3 individual organic compound. For a 1-litre sample of air, the range is approximately 1 mg/m3 to 1 000 mg/m3 individual organic compound, and pro rata.

 

This part of ISO 16200 gives general guidance for the sampling and analysis of volatile organic compounds (VOCs) in workplace air by solvent desorption/gas chromatography using diffusive sampling. This part of ISO 16200 is applicable to a wide range of VOCs, including hydrocarbons, halogenated hydrocarbons, esters, glycol ethers, ketones and alcohols. A number of devices and sorbents are recommended for the sampling of these VOCs, each sorbent having a different range of applicability. Note 1 to entry Activated coconut shell charcoal is frequently used. Very polar compounds may require derivatization, very low boiling compounds may only be partially retained by the sorbents, polar or high boiling compounds may not be quantitatively extracted by the chosen solvent. In these cases, their concentration may be quantitatively determined, provided that reverse diffusion and analytical recovery studies are available. This part of ISO 16200 is valid for the measurement of airborne vapours of VOCs in a concentration range of approximately 0,1 mg/m3 to 1 000 mg/m3 individual organic for an exposure time of 8 h. The upper limit of the useful range is set by the sorptive capacity of the sorbent used and, subject to dilution of the analysed solution, by the linear dynamic range of the gas chromatograph, column and detector or by the sample splitting capability of the analytical instrumentation used. The lower limit of the useful range depends on the noise level of the detector and on blank levels of analyte and/or interfering artefacts on the sampling devices or in the desorption solvent. Artefacts are typically sub-nanogram for activated charcoal, but higher levels of aromatic hydrocarbons have been noted in some batches. By applying this part of ISO 16200, the lower limits of quantification achieved are typically in the range of 0,01 µg to 1 µg of a given VOC per sample. Determination of the blank value for target organic compounds is recommended for each lot of samplers.

This document specifies two methods for the determination of total organic carbon (TOC) in sludge, treated biowaste, soil and waste samples containing more than 0,1 % carbon in relation to the dry matter (dm). This document is validated for sludge, biowaste, soil, and waste (see also Annex A for the results of the validation).

 

Specifies a method for the determination of the total carbon content in soil after dry combustion. The organic carbon content is calculated from this content after correcting for carbonates present in the sample. If carbonates are removed beforehand, the organic carbon content is measured directly. Applicable to all types of air-dried soil samples.

 

This document specifies a basic method of determining the particle size distribution applicable to a wide range of mineral soil materials, including the mineral fraction of organic soils. It also offers procedures to deal with the less common soils mentioned in the introduction. This document has been developed largely for use in the field of environmental science, and its use in geotechnical investigations is something for which professional advice might be required. A major objective of this document is the determination of enough size fractions to enable the construction of a reliable particle-size-distribution curve. This document does not apply to the determination of the particle size distribution of the organic components of soil, i.e. the more or less fragile, partially decomposed, remains of plants and animals. It is also realized that the chemical pre-treatments and mechanical handling stages in this document could cause disintegration of weakly cohesive particles that, from field inspection, might be regarded as primary particles, even though such primary particles could be better described as aggregates. If such disintegration is undesirable, then this document is not used for the determination of the particle size distribution of such weakly cohesive materials.

 

This document specifies a method used to determine the resistance to slow crack growth (SCG) of thermoplastic materials, pipes and fittings. The test is applicable to samples taken from compression moulded sheets, extruded rods, sheets or pipes and injection moulded fittings of suitable thickness. The method is suitable for an accelerated slow crack growth characterization at ambient temperatures of 23 °C. This document specifies test parameters for polyethylene (PE), polypropylene (PP) and unplasticized polyamide (PA-U). Furthermore, this test can be applied to characterise the slow crack growth resistance of virgin, as well as non-virgin (reused, recycled) thermoplastic materials[5]. This test method can be adapted for other thermoplastics materials by developing the procedure using different test parameters.
