This part of ISO 13849 specifies a methodology and provides related guidance for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software. This document specifies the characteristics needed to determine the performance level required of safety functions. This document applies to SRP/CS for high demand and continuous mode including their subsystems, regardless of the type of technology and energy (e.g. electrical, hydraulic, pneumatic, mechanical), for many kinds of machinery. The standard does not apply to low demand mode.

This document does not specify the safety functions or required performance levels that are to be used in particular applications.

This document does not give specific requirements for the design of products that are parts of SRP/CS.

This document does not provide specific measures for security (e.g. physical, IT-security, cyber security) aspects.

NOTE 1 This document specifies a methodology for SRP/CS design without considering if certain machinery (e.g. mobile machinery) requires specific requirements. These specific requirements can be considered in a Type-C standard.

NOTE 2 See IEC 61508 for low demand mode.

NOTE 3 See also ISO/TR 22100-4 for IT-security aspects and IEC/TR 63074 for security aspects.

ISO 19918 describes laboratory test methods to determine the resistance of materials, closures, and seams used in personal protective equipment (PPE) to permeation by solid or liquid chemicals with low vapour pressure (less than 133,322 Pa at 25 °C) and/or insolubility in water or other liquids commonly used as collection media. These chemicals that are often part of pesticide formulations and other mixtures cannot be measured using other standards for measuring permeation. This test method is suitable for field strength and concentrated pesticide formulations as well as other mixtures in which the active ingredient is a chemical with low vapour pressure and/or low solubility in commonly used liquid and gaseous collection media. This test method is not intended to be used in place of standards such as ISO 6529, EN 16523-1 and ASTM F739, which measure permeation of chemicals that are either volatile or soluble in water or other liquids that do not interact with the material being tested. ISO 19918 is not suitable for measurement of volatile chemicals that may evaporate before the chemical analysis is complete. The degree of contamination depends on numerous factors, such as type of exposure, application technique, and chemical formulation. As the level of exposure can vary considerably, this method is designed to rate relative performance of PPE materials for different durations. This method is designed to measure cumulative permeation. Breakthrough time cannot be measured by this method. This test method does not measure resistance to penetration or degradation. The test method standard may be used for the evaluation of PPE materials that are new or those for which the product standard requires treatment, such as laundering or simulated abrasion. Details of the treatment shall be reported.

Although ISO 20179 for microcystin analysis by HPLC UV has been elaborated, the UV detection nevertheless requires several steps of sample clean-up and concentration to achieve detection limits in the range of micrograms per litre, μg/l. A more sensitive and effective method for quantitative determination of microcystins is been required.

This document specifies a method for the quantitation of twelve microcystin variants (microcystin-LR, -LA, -YR, -RR, -LY, -WR, -HtyR, -HilR, -LW, -LF, [Dha7]-microcystin-LR, and [Dha7]-microcystin-RR) in drinking water and freshwater samples. The method can be used to determine further microcystins, provided that analytical conditions for chromatography and mass spectrometric detection has been tested and validated for each microcystin. Samples are analysed by LC-MS/MS using internal standardization.

This method is performance based. The analyst is permitted to modify the method, e.g. increasing direct flow injection volume for low interference samples or diluting the samples to increase the upper working range limit, provided that all performance criteria in this method are met.

Detection of microcystins by high resolution mass spectrometry (HRMS) as an alternative for tandem mass spectrometry (MS/MS) is described in Annex A.

An alternative automated sample preparation method based on on-line solid phase extraction coupled to liquid chromatography is described in Annex B.

When instrumental sensitivity is not enough to reach the method detection limits by direct flow injection, a solid phase extraction clean-up and concentration step is described in Annex C.

- calibration of an instrument with one or two calibration gas mixtures,

- determining the composition of a gas sample, and

- evaluating the uncertainty of the composition of the gas sample in relation to the uncertainty of the composition of the calibration gases used, and the contribution of the measurement process.

This International Standard sets requirements to, and acceptance criteria for, the utilization of different measurement calibration designs with a limited (i.e. minimum) number of calibration gas mixtures used in calibration.

The methods in this International Standard are described for amount-of-substance fractions, but are also applicable for other composition quantities (such as mass fractions, volume fractions, or concentrations).

This document presents a method to quantify the soil organic carbon and nitrogen stocks in mineral soils at plot scale. It also provides guidance on how to detect and quantify simultaneously the variations of the carbon and nitrogen stocks over time in mineral soils at field scale. It is based on several documents already published [2, 3, 4, 5, 6, 7, 8].

This guidance does not apply to organic soils, soils with permafrost, wetland soils, or to soil layers prone to submergence below the groundwater table.

NOTE 1 The potential for soil to store carbon is viewed as a possible way to mitigate greenhouse gas emissions (GHGs). Knowledge on soil nitrogen is also crucial as nitrogen interacts with carbon cycling through plant and organic matter decomposers nutrition, and leakage of N is of environmental concern (e.g. N2O emissions, NO3- leaching). Therefore, it is becoming increasingly important to measure accurately the impact of changes of land uses and practices on organic carbon and nitrogen stocks.

NOTE 2 While understanding changes in soil inorganic carbon also will be required to understand the land-atmosphere exchange of CO2, measuring stocks of soil inorganic carbon is outside the scope of this guidance document.
