This document specifies a method for the quantification of four tobacco specific nitrosamines (TSNAs) in the total particulate matter of mainstream cigarette smoke under intense smoking conditions (ISO 20778) by using reversed phase high performance liquid chromatography with tandem mass spectrometry (LC-MS/MS). The quantified TSNAs are: N-nitrosonornicotine (NNN), N-nitrosoanatabine (NAT), N-nitrosoanabasine (NAB) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK).

This document defines the requirements concerning operator safety and environmental protection for closed transfer systems for liquid formulations of plant protection products (PPP) or compatible products in 1 to 20 litre containers and specifies the maximum potential contamination during any single transfer operation. The actions required to be completed in a single transfer operation are: Starting from the container being removed from any secondary packaging, connection of the transfer device, completion of the product transfer procedure, measurement of part of packs where applicable, rinsing of the pack and the transfer device, and removal of the pack ready for storage or disposal.

This document does not have the purpose of determining the actual level of operator exposure experienced when filling or using the application equipment.

This document specifies a method for the determination of benzo[a]pyrene (B[a]P) in the total particulate matter (TPM) of cigarette mainstream smoke using gas chromatography/mass spectrometry (GC/MS) with methanol as extraction solvent.

This method is specified using ISO 20778 smoking parameters. An alternative method for the determination of B[a]P is specified in ISO 23906-2 with a different clean-up using cyclohexane solvent and a shorter total analytical time.

This part of ISO 4254, intended to be used together with ISO 4254-1, specifies the safety requirements and their verification for the design and construction of trailed loader wagons and forage transport wagons and silage and forage body works for carrier vehicles, where the discharge is done at the rear of the machine and which is intended for the use by only one person (operator). In addition, it specifies the type of information on safe working practices including residual risks to be provided by the manufacturer.

This document is applicable to VC-A2 and VC-B1electrical systems used on tractors, self-propelled ride-on machines, interchangeable towed implements, semi-mounted implements and mounted implements used in agriculture and forestry; it also applies to earth-moving machinery (EMM) as defined in ISO 6165.

This document provides both general design requirements and guidelines for protection of operators and bystanders against electric shock and electrically induced fire related to machinery onboard components, equipment, and systems operating within VC-A2 and VC-B1 ranges, where VC for AC , and DC voltages can be synthesized by power electronic converters.

Requirements for machines which are both externally or self-powered are included in this document.

Alternative safety requirements can be necessary for special equipment or components such as underground mining equipment. This standard does not address the additional risks for machines operating in potentially explosive atmospheres.

This document deals with all significant hazards, hazardous situations or hazardous

events relevant to agricultural, forestry, or earthmoving machinery within its scope (see Annex A), when the machinery is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. It specifies appropriate technical measures for eliminating or reducing risks arising from significant hazards, hazardous situations, or hazardous events during commissioning, operation, and maintenance.

Even though this document addresses most hazards associated with the use of electrical systems within the voltage ranges above, owing to the possible presence of additional electrical hazards, conformance with it cannot be taken as an absolute guarantee of electrical safety. Areas of concern are included in the list of significant hazards found in Annex A.

This standard is not applicable to machines manufactured before the date of its publication.

NOTE 1 Although 12 VDC and 24 VDC systems are below the limits of this standard, meeting appropriate requirements of this standard, including those governing PELV (Protective Extra Low Voltage), ensures that proper protection exists between the covered systems and lower voltage systems.

Note 2 For machinery with multiple rated voltages, with at least one rated beyond the scope (> VC-B1), refer to ISO 16230-1 for ag machinery or ISO 14990 (all parts) for EMM, to address the interactions of circuits of different ranges.

This standard describes a method of Iodium-131, Caesium-134 and Caesium-137 massic activity (Bq/kg) determination in animal feed. Today, the most commonly used method for identification and quantification of radioactivity from these radionuclides in feed samples is high-resolution gamma-ray spectrometry. It is based on analysis of full-energy peaks (FEP) of the emitted gamma rays. Therefore, care should be taken to use appropriate energy and efficiency calibrations for each detector and test portion used. In this standard, general guidance on the preparation of feed samples is provided together with specific information on high resolution gamma-ray spectrometry of the three radionuclides Iodium-131, Caesium-134 and Caesium-137. More information on these and related topics can be found in specific standards referred to in this document. For example, generic advice on the equipment selection, detectors and quality assurance for gamma-ray spectrometry can be found in ISO 20042:2016. The current standard aims to be complementary to existing standards, as an aid to laboratory practitioners that are faced with a situation, which requires response to the current topic without having to go through and interpret standards with general descriptions of gamma-ray spectrometry in order to measure in a standardised way. This standard contains information specific to the three radionuclides that it covers. Examples are provided in Annex …(to be added).
