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 European Standard describes the specifications and test methods for gravity fed devices for conditioning of drinking water that are not connected to the mains water distribution system in buildings, known as jug water filter systems. It also gives instructions for the user manuals, so that the jug water filter system can be used and maintained properly. Jug water filter systems are intended to modify the properties of drinking water only, and are not designed to make non-potable water safe for drinking. The scope of this document does not extend to combination systems that require an electrical power supply such as water heaters and water coolers systems. NOTE 1 Although jug water filter systems are covered by the widely harmonized food legislation (EU Regulations 178/2002 and 1935/2004), existing national regulations concerning the use and or the characteristics of these products remain in force NOTE 2 This standard provides no information as to whether the product is used without restriction in any of the Member States of the EU or EFTA.

 

This European Standard specifies a method for the determination of the dissolved residual matter, also known as evaporation residue, in liquefied petroleum gases (LPG), by gas chromatography in the range of (10 to 600) mg/kg (ppm mass). This test method quantifies soluble organic compounds (hydrocarbon materials), sometimes called ‘evaporation residue’, which can be present in liquefied petroleum gases and which are substantially less volatile than the LPG product, i.e. with a boiling point between 174 °C and 522 °C (C10 to C40). Higher boiling materials, or materials that adhere permanently to the chromatographic column, will not be detected. WARNING - This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

 

This document specifies the test method and performance metrics to evaluate the behaviour of a vehicle equipped with door open warning system during several accidental scenarios. These potential accidents occur when a door is about to be opened and there is a risk of collision due to the vehicle door opening. This document applies to category M1 and N1 vehicles equipped with a door open warning system. NOTE Depending on accidentology, only a part of the scenarios can be used for an evaluation of performance.

 

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.
