This document specifies safety requirements for hand-held non-electric power tools intended for installation of a fastener, (hereinafter referred to as “fastener driving tools”) forming a mechanical connection or attachment with the workpiece. This document is applicable to fastener driving tools that are powered by compressed air or combustible gases (which may be ignited by a battery or accumulator) and where the energy is transmitted to an impacted element by an intermediary component that does not leave the device. NOTE These fastener driving tools are intended to be used by one operator and supported by the operator's hand or hands, with or without a suspension, e.g. a balancer. This document is applicable to fastener driving tools in which energy is applied to a loaded fastener for the purpose of driving this into a workpiece. This document deals with all significant hazards, hazardous situations or hazardous events relevant to fastener driving tools for fasteners when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer, with the exception of the use of power tools in potentially explosive atmospheres. This document is not applicable to fastener driving tools in which the energy for driving fasteners is drawn from powder-actuated cartridges, hydraulics or from any type of electrical supply. This document does not deal with special requirements and modifications of hand-held power tools for the purpose of mounting them in a fixture. This document is not applicable to fastener driving tools or fastener driving tool components which are manufactured before the date of publication of the standard. NOTE ISO 80079–36 gives requirements for non-electrical equipment for potentially explosive atmospheres.

This document specifies a method for the determination of cetane number of diesel fuels by air flow regulation in a standard test engine. This document is applicable to various types of diesel fuels, including vehicle diesel, bio-diesel, synthetic diesel, and similar unconventional products. The cetane number measurement range is from 0 CN to 100 CN, whereas a typical cetane number range of 25 CN to 70 CN. However, the precision for synthetic and unconventional diesel has not been established.

ISO 19377:2017 describes test methods for determining the deviation of the path travelled by a vehicle during a braking manoeuvre induced by an emergency braking system from a pre-defined desired path. The purpose of this document is the evaluation of the vehicle path during and following the system intervention. The corrective steering actions for keeping the vehicle on the desired path can be applied either by the driver or by a steering machine or by a driver assistance system. By making this document open for either open-loop or closed-loop testing, it is possible to apply the test method for evaluating how well the vehicle can be kept within user-defined lane markings after the system intervention, and also for evaluating the precision of the interaction between the emergency braking system and an active lane keeping system.

This document applies to heavy vehicles equipped with an advanced emergency braking system (AEBS), including commercial vehicles, commercial vehicle combinations, buses and articulated buses as defined in ISO 3833 (trucks and trailers with maximum weight above 3,5 tonnes and buses and articulated buses with maximum weight above 5 tonnes, according to ECE and EC vehicle classification, categories M3, N2, N3, O3 and O4).

NOTE The test method is intended to evaluate the entire vehicle behaviour, not for defining system requirements for the AEBS, which is done in the respective standards created by ISO/TC 204.

This document specifies the long-term sampling of PCDDs/PCDFs/PCBs. There are three different sampling methods, which are based on the three different principles described in EN 1948-1, but partially modified for long-term sampling requirements:

— filter/condenser method;

— dilution method;

— cooled probe method.

Each sampling method is illustrated in detail in Annex D. The sampling methods described in this document are designed for a sampling duration of typically up to four weeks.

Additionally, this document specifies a framework of quality control requirements for any long-term sampling method.

With the methods described, experiences were gained for a concentration range up to 4,0 ng TEQ/m3 at various stationary sources (e.g. waste incinerators, sinter plants, cement kilns).

For complete implementation of the measurement method, the use of EN 1948-2 and EN 1948-3 describing extraction, clean-up, identification, and quantification, respectively, is necessary in order to determine PCDDs/PCDFs. Additionally, EN 1948-4 is necessary for PCBs.

This document specifies a method for determining the dynamic surface tension of liquids based on the pressure in gas bubbles. The dynamic surface tension of solutions is influenced by surface-active molecules in the solution (often surfactants in water-based solutions). The surface tension is measured at a newly created interface depending on the age of this surface. This allows direct conclusions to be drawn about how quickly and strongly the surfactants in the solution reduce the surface tension of a new surface. The interface used to determine surface tension is renewed with each gas bubble. Due to the principle, very short measurement times in the millisecond range are possible, which makes the test method particularly suitable for surfactant-containing solutions of high concentration (significantly above the critical micelle concentration), e.g. in electroplating baths, cleaning baths, preferably low-viscosity Newtonian paints, inks. The sequence of air bubbles resulting from a gas volume flow enables continuous measurement without the sample having to flow through the measuring system. For the purpose of controlling surfactant concentration, surface tension is monitored at an appropriate, well-defined surface age.

This document defines test methods and criteria for distinguishing intrinsically biodegradable plastic materials from those that are persistent. Biodegradability is inferred from biodegradation tests conducted under aerobic conditions, i.e. under the conditions typically found in most natural habitats. Plastics that undergo ultimate biodegradation under aerobic conditions in a manner similar to natural polymer materials are defined as biodegradable plastics. This document describes a method for distinguishing between non-biodegradable plastics, which do not biodegrade even when environmental conditions are favourable for biodegradation (including aerobic conditions), and biodegradable plastics, i.e. those that biodegrade upon contact with active microorganisms when environmental conditions are favourable for biodegradation.

The aim is to demonstrate ultimate aerobic biodegradability of plastic materials, i.e. the intrinsic potential for conversion to carbon dioxide, water and biomass by aerobic microorganisms in an oxygen-rich environment, which is representative of most natural environments.

The potential for biodegradation should be verified using alternative tests and criteria, if a deposition in a permanent anaerobic environment (e.g. deep subsurface environments, wetlands and swamps, anoxic zones in oceans and lakes) is expected.

NOTE          Currently, there are no methodologies or criteria available to verify accumulation due to the lack of biodegradation of plastics in such anaerobic habitats.

The plastic materials identified as intrinsically biodegradable following this document can be used in the design of products with a high risk of dispersion whenever the use of biodegradable components is searched by the designer. Intrinsically non-biodegradable components are not susceptible to biodegradation and therefore cannot be removed from the environment by the action of micro-organisms. This factor tends to increase the residence time of products in the environment. In addition, their eventual degradation, mainly due to abiotic factors, results in persistent fragments (microplastics).

The test scheme described in this document is not specific to any particular application. Rather, it is a framework methodology that can be used in different industries to identify biodegradable plastics that can be used to make different types of products and for different applications. For the characterisation and environmental assessment of products placed on the market containing plastics identified as biodegradable according to this document, reference is made to the specific product standards, where available. This document only deals with the definition of intrinsic biodegradability of plastic materials, without defining the hazard of the products, which requires a specific assessment that is beyond the scope of this document. The rate of biodegradation of a plastic object as a function of environmental conditions cannot be determined from this document. Therefore, this document is not sufficient to carry out an analysis of the ecological risk associated with the dispersal of products, as this requires an assessment of the intrinsic hazard, of the environmental fate, in addition to the assessment of biodegradability.

The methodology described in this document does not apply to applications covered by mandatory regulations.
