This document describes procedures for determination of the compressive behaviour of ceramic matrix composite materials with continuous fibre reinforcement at room temperature. This method applies to all ceramic matrix composites with a continuous fibre reinforcement, uni-directional (1D), bi-directional (2D) and tri-directional (xD, with 2 < x < 3), tested along one principal axis of reinforcement or off axis conditions. This method also applies to carbon-fibre-reinforced carbon matrix composites (also known as carbon/carbon or C/C). Two cases of testing are distinguished: compression between platens and compression using grips.

ISO 9455-17:2002 specifies a method of testing for deleterious effects that may arise from flux residues after soldering or tinning test coupons. The test is applicable to type 1 and type 2 fluxes in solid or liquid form, or in the form of flux-cored solder wire, solder preforms or solder paste constituted with eutectic or near-eutectic tin/lead solders.This test method is also applicable to fluxes for use with lead-free solders. However, the soldering temperatures may be adjusted with agreement between tester and customer.

This document specifies the general safety requirements for demountable machines and trailers, including road-rail trailers - henceforward referred to as ‘machines, for use when travelling and working on railway track.NOTE Trailers, including road-rail trailers, are considered as machines because they are moved along the track by powered machines.This document specifies the requirements to deal with the common hazards presented by their use on the railway during transport, assembly and installation, commissioning, travelling and working on track, use including setting, programming, and process changeover, operation, cleaning, fault finding, maintenance and de-commissioning of the machines and associated equipment when they are used as intended and under conditions of misuse which are reasonably foreseeable.These machines will not run on railway lines open to normal traffic.NOTE Other rail mounted railway maintenance and infrastructure inspection machines are dealt with in other European standards, see Technical Report CEN/TR 17498:2020.This document is also applicable to machines and associated equipment that in working mode are partly supported on the ballast or the formation.The requirements in this document are based on the assumption that the machines are used, operated and maintained by skilled person(s).This document does not apply to the following:- requirements for quality of the work or performance of the machine;- use of separate equipment temporarily mounted on machines;- machines that utilize external power supplies such as the overhead contact line system for traction purposes or as a power source;- hazards due to air pressure caused by the passing of high-speed trains at more than 200 km/h;- operation subject to special rules, e.g. potentially explosive atmospheres;- hazards due to natural causes, e.g. earthquake, lightning, flooding;- working methods;- operation in severe working conditions requiring special measures, e.g. corrosive environments, contaminating environments, strong magnetic fields;- hazards occurring when used to handle suspended loads which may swing freely.

This document specifies the crucial steps of a quantitative real-time polymerase chain reaction (qPCR) method to quantify the abundance of specific mRNA molecules extracted from Daphnia magna.The method allows the identification of molecular responses to exposures for potentially toxic substances through the analysis of the abundance of specific mRNA molecules. In this document, the central genes involved in reproductive and toxic responses are included.NOTE The selection of genes can be adapted to specific exposure conditions, for example, exposure to known toxic substances, by adding genes known to respond to a specific insult.The present method allows for rapid, robust and sensitive detection of molecular responses and can be used to analyse the toxic effects of water leachates from soil and waste. The method gives information of the concentration of a substance or test-liquid at which toxic effects begin to occur prior to observations of reproductive or toxic effects at higher levels of organization, which reduces the need for the use of safety factors in toxicity assessment.The method is useful in several types of risk assessment. In this document, the genes studied are appropriate for the assessment of the risks when recycling materials and for the classification of waste, but the method can be adapted to other types of risk assessment by including other genes.

Heavy duty refers to situations where the stresses applied to the rope are either high or vary by a large amount during service.This document refers to round wires and three types of shaped wire: full lock (Z), half lock (H) and trapezoidal (T).It does not apply to steel wire taken from manufactured ropes.This document specifies the following for cold drawn non alloyed steel wire for ropes for high duty applications:- dimensional tolerances;- mechanical characteristics;- requirements relating to the chemical composition of the steel wire;- conditions to be satisfied by any coating.

This document specifies the basic formulae for use in the determination of the surface load capacity of straight and helical (skew), Zerol and spiral bevel gears including hypoid gears, and comprises all the influences on surface durability for which quantitative assessments can be made. This document is applicable to oil lubricated bevel gears, as long as sufficient lubricant is present in the mesh at all times. The formulae in this part of ISO 10300 are based on virtual cylindrical gears and restricted to bevel gears whose virtual cylindrical gears have transverse contact ratios of eva < 2. The results are valid within the range of the applied factors as specified in ISO 10300-1 (see ISO 6336-2[1]). Additionally, the given relations are valid for bevel gears of which the sum of profile shift coefficients of pinion and wheel is zero (see ISO 23509). The formulae in this document are not directly applicable to the assessment of other types of gear tooth surface damage, such as plastic yielding, scratching, scuffing or any other type not specified.
