This document specifies a method for the quantitative determination of the sum of short-chain polychlorinated n-alkanes also known as short-chain polychlorinated paraffins (SCCPs) in the carbon bond range n-C10 to n-C13 inclusive, in mixtures with chlorine mass fractions ("contents") between 50 % and 67 %, including approximately 6 000 of approximately 8 000 congeners.

This method is applicable to the determination of the sum of SCCPs in unfiltered surface water, ground water, drinking water and waste water using gas chromatography-mass spectrometry with electron capture negative ionization (GC-ECNI-MS).

Depending on the capability of the GC-ECNI-MS instrument the concentration range of the method is from 0,1 μg/l or lower to 10 μg/l. Depending on the waste water matrix, the lowest detectable concentration is estimated to be > 0,1 μg/l.

This International Standard specifies a test method for measuring the heat-transferred through horizontally mounted flame-resistant textile materials when exposed to a combination of convective and radiant heat. The exposure conditions are adjusted to be approximately a 50/50 mixture of pure convective heat and pure radiant heat. The total exposure heat flux is 84 kW/m2.

This test method can be used for any type of sheet material used either as a single layer or in a multilayer construction when all structures or sub-assemblies are made of flame-resistant materials. It is not intended to be used on materials that are not flame resistant.

This test method is not intended for evaluating materials exposed to any other type of thermal-energy sources, such as radiant heat only or flame contact only. Use ISO 6942 for evaluating materials for exposure to radiant heat only and use ISO 9151 when evaluating materials due to flame contact only.

This test method may not identify textile materials that can ignite and continue to burn after exposure to convective and radiant heat.

This International Standard should be used to measure and describe the properties of materials, products or assemblies in response to both convective and radiant heat under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, the results of this test method may be used as elements of a fire-risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end-use.

NOTE This test method may not correlate to the heat-insulation performance of vertically oriented flame-resistant textile materials when exposed to convective and radiant heat or used in actual clothing configurations.

This international standard specifies the use of FTIR spectrometry for determining the concentrations of individual volatile organic compound (VOC) in waste gases from non-combustion processes. The method can be employed to continuously analyse sample gas which is extracted from ducts and other sources. A bag sampling method may also be applied, if the compounds do not adsorb on the bag material. This would only be used in cases where it is difficult or impossible to obtain a direct extractive sample.

The principle, sampling procedure, IR spectral measurement and analysis, calibration, handling interference, QA/QC procedures and some essential performance criteria for measurement of individual VOCs are described in this standard.

Note 1 The practical minimum detectable concentration of this method depends on the FTIR instrument (i.e. gas cell path length, resolution, instrumental noise and analytical algorithm used), compounds, and interference specific (e.g. water and CO2).

This International standard specifies two laboratory test methods for the determination of effective shear strength parameters for soils under consolidated drained conditions using either a shear box or ring shear device. The shearbox test is generally used for the determination of peak effective shear strength parameters. The ring shear test is generally used for the determination of residual effective shear strength parameters of fine grained soils.

Residual effective shear strength parameters may also be obtained from shear box tests and peak effective shear strength parameters may also be obtained from ring shear tests.

This standard is applicable to the laboratory determination of effective shear strength parameters for soils in direct shear within the scope of geotechnical investigations.

The test method consists of placing the test specimen in the direct shear device, applying a pre-determined normal stress, providing for draining (and wetting if required) of the test specimen, consolidating the specimen under normal stress and then shearing the specimen. This shearing is imposed by displacing one part horizontally, relatively with respect to the other part of the specimen at a constant rate of shear-deformation. The shearing force and the horizontal and vertical displacements are measured as the specimen is sheared. Shearing is applied slowly enough to allow excess pore pressures to dissipate by drainage so that effective stresses are equal to total stresses.

The tests included in this standard are for undisturbed, remoulded, re-compacted or reconstituted soils. The procedure describes the requirements of a determination of the shear resistance of a specimen under a single normal stress. Generally three or more similar specimens from one soil are prepared for shearing under three different normal pressures to allow the shear strength parameters to be determined.

Special procedures for preparation and testing the specimen, such as staged loading and pre-shearing or for interface tests between soils and other materials, are not covered in this standard procedure.

NOTE 1 This document fulfils the requirements of the determination of the drained shear strength of soils in direct shear for geotechnical investigation and testing in accordance with EN 1997-1 and EN 1997-2.

This International Standard specifies methods for the laboratory determination of the water flow characteristics in soil.

This International Standard is applicable to the laboratory determination of the coefficient of permeability of soil within the scope of geotechnical investigations.

The permeability test is carried out on a cylindrical test specimen that is either confined laterally by a rigid container or by a flexible membrane. The specimen is subjected to differential hydraulic head and the water flow is measured under either a constant or falling head. The results are used to determine the coefficient of permeability of the soil specimen. Tests may be carried out on undisturbed, remoulded, compacted or reconstituted specimens.

The calculation of coefficient of permeability assumes the application of Darcy’s law for laminar flow under saturated conditions.

The size of the specimen may not adequately represent the fabric features present in field conditions.

NOTE This document fulfils the requirements of the determination of the coefficient of permeability of soils in the laboratory for geotechnical investigation and testing in accordance with EN 1997-1 and EN 1997-2.

This part of ISO 21268 specifies a test providing information on leaching of soil and soil materials under

the experimental conditions specified hereafter, and particularly at a liquid to solid ratio of 2 l/kg dry

matter.

This part of ISO 21268 has been developed to measure the release of inorganic and organic constituents

from soil and soil material and the ecotoxicological effects of eluates with respect to micro-organisms,

fauna and flora. The test is not suitable for constituents that are volatile under ambient conditions. For

ecotoxicological testing, see ISO 15799.

NOTE 1 Volatile organic constituents include the low-molecular-weight components in mixtures such as

mineral oil.

NOTE 2 It is not always possible to optimise test conditions simultaneously for inorganic and organic

constituents and optimum test conditions may also vary between different groups of organic constituents. Test

requirements for organic constituents are generally more stringent than those for inorganic constituents. The test

conditions suitable for measuring the release of organic constituents will generally also be applicable to inorganic

constituents.

NOTE 3 For ecotoxicological testing, eluates representing the release of both inorganic and organic

contaminants are needed. In this document, ecotoxicological testing is also meant to include genotoxicological

testing.

The test procedure specified in this part of ISO 21268 produces eluates, which are subsequently

characterised by existing physical, chemical and ecotoxicological standard methods.

This procedure is not applicable to materials with a dry-matter-content ratio lower than 33 %.

This test is mainly aimed at being used for routine and control purposes, and it cannot be used alone to

describe all leaching properties of a soil. Additional leaching tests are needed for that extended goal.

This part of ISO 21268 does not address issues related to health and safety. It only determines the

leaching properties as outlined in Clause 4.

This part of ISO 21268 specifies a test, which is aimed at determining the leaching behaviour of

inorganic and organic constituents from a soil and soil material. The method is a once-through

percolation test with water (0,001 mol/l CaCl2) under standardized conditions of flow rate. The

material is leached under dynamic hydraulic conditions. The eluates obtained can be used to determine

the ecological properties of the soil with respect to micro-organisms, flora and fauna. The test results

enable the distinction between different release patterns, for instance wash-out and release under the

influence of interaction with the matrix, when approaching local equilibrium between material and

leachant.

This test method produces eluates, which can subsequently be characterised by physical, chemical and

ecotoxicological methods in accordance with existing standard methods. The results of eluate analysis

are presented as a function of the liquid/solid (L/S) ratio. The test is not suitable for species that are

volatile under ambient conditions.

NOTE 1 Volatile organic constituents include the low-molecular-weight components in mixtures such as

mineral oil.

NOTE 2 It is not always possible to optimise test conditions simultaneously for inorganic and organic

constituents and optimum test conditions can also vary between different groups of organic constituents. Test

requirements for organic constituents are generally more stringent than those for inorganic constituents. The test

conditions suitable for measuring the release of organic constituents will generally also be applicable to inorganic

constituents.

NOTE 3 For ecotoxicological testing, eluates representing the release of both inorganic and organic

contaminants are needed. In this document, ecotoxicological testing is also meant to include genotoxicological

testing.

NOTE 4 The test is generally not suitable for soils with hydraulic conductivities below 10-8 m/s (see also Annex

B). It might be difficult to maintain the designated flow rate already in the range of saturated hydraulic

conductivity between 10-7 m/s and 10-8 m/s.

The application of this test method alone is not sufficient for the determination of the leaching

behaviour of a material under specified conditions different to those from the test procedure, since this

generally requires the application of several test methods, behavioural modelling and model validation.

This part of ISO 21268 does not address issues related to health and safety. It only determines the

leaching properties as outlined in Clause 4.

This part of ISO/TS 21268 specifies a test method to obtain information on the short- and long-term

leaching behaviour and characteristic properties of materials.

It applies to the determination of the influence of pH on the leachability of inorganic and organic

constituents from soil and soil material, and the ecotoxicological effects of eluates with respect to

microorganisms, fauna and flora. The test is not suitable for constituents that are volatile under ambient

conditions. The equilibrium condition, as defined in this part of ISO/TS 21268, is established by the

addition of predetermined amounts of acid or base to reach desired final pH values.

The test procedure specified in this part of ISO/TS 21268 produces eluates that are subsequently

characterized by physical, chemical and ecotoxicological standard methods.

For the purposes of ecotoxicological tests, the relevant pH range (see 9.2) will usually be pH 5 to 9.

NOTE 1 Volatile organic constituents include the low molecular weight components in mixtures such as

mineral oil.

NOTE 2 It is not always possible to optimize test conditions simultaneously for inorganic and organic

constituents and optimum test conditions may also vary between different groups of organic constituents. Test

requirements for organic constituents are generally more stringent than those for inorganic constituents. The test

conditions suitable for measuring the release of organic constituents will generally also be applicable to inorganic

constituents.

NOTE 3 For ecotoxicological testing, eluates representing the release of both inorganic and organic

contaminants are needed. In this document, ecotoxicological testing is meant to include genotoxicological testing.

This test cannot be used alone to determine the total leaching behaviour of a soil. More leaching tests

are needed for that extended goal. This part of ISO/TS 21268 does not address issues related to health

and safety. It only determines the leaching properties outlined in Clause 5.

1.01 This International Standard gives general guidance for the sampling and analysis of airborne organic isocyanates in workplace air.

1.02 This International Standard is appropriate for a wide range of organic compounds containin isocyanate groups, including monofunctional isocyanates (e.g. phenyl isocyanate), diisocyanate monomers (e.g. 1,6-hexamethylene diisocyanate (HDI), toluene diisocyanate (TDI), 4,4’ diphenylmethane diisocyanate (MDI), and isophorone diisocyanate (IPDI)), prepolymers (e.g. the biuret and isocyanurate of HDI), as well as chromatographable intermediate products formed during production or thermal breakdown of polyurethane.

1.03 In mixed systems of HDI and IPDI products, it is impossible to identify and quantify low levels of IPDI monomer using this International Standard, due to coelution of IPDI monomer with HDI-uretidinedione.

1.04 It is known that the method underestimates the oligomer in MDI-based products. Total isocyanate group (NCO) will be underestimated in MDI-based products by about 35% as compared to dibutylamine titration.

1.05 The method has been successfully modified to be used with LC-MS-MS for TDI monomer using an isocratic 70% acetonitrile/30% 10 mM ammonium formate mobile phase.

1.06 The useful range of the method, expressed in moles of isocyanate group per species per sample, is approximately 1 × 10−10 to 2 × 10−7. The instrumental detection limit for the monomers using both ultraviolet (UV) detection and fluorescent (FL) detection is about 2 ng monomer per sample.
The useful limit of detection for the method using reagent impregnated filters is about 10-20 ng monomer per sample for both UV and FL detection. For a 15 l sample, this corresponds to 0.7-1.4 µg.m-3. For impinger samples, which require solid phase extraction, experience has shown that the useful limit of detection is about 30-80 ng monomer per sample.
