This activity w ill be the parallel development of EN 16603-20-40 and ECSS-E-ST-20-40C. The scope shall cover the areas of existing ASIC and FPGA engineering chapter 5 of ECSS-Q-ST-60-02C, but w ith w ider breadth and greater depth, covering engineering requirements of end-to-end development flow s, from specification of requirements to validation of prototypes, of the follow ing monolithic devices for its use in space: • ASICs (distinguishing digital, analogue and mixed-signal development flow s) • FPGAs (distinguishing three technology families: SRAM, FLASH and anti-fuse technologies) • ASIC and FPGA System-on-Chip embedding processor cores w hich have external “softw are programme” dependencies to be addressed during the SoC development, resulting in SW-HW co-design requirements.

This document, together with EN 746-1, EN 746-2 and EN 746-11, specifies the safety requirements for industrial thermoprocessing equipment ( IThE) with "Open firing oxy-fuel gas welding equipment", as well as the relevant gas distribution and protective systems. This document applies to IThE supplied with fuel gases. IThE in the scope of application of this document shall be able to be operated under the following ambient conditions: -? temperature range; -? during operation: +5°C to +40°C; -? during transportation and storage: -5°C to +55°C; -? relative humidity: up to 90% at 20°C, non-condensing. This document covers the significant hazards, hazardous situations and events listed in Appendix A for oxy-fuel IThE, associated gas supply systems and protective systems on the basis that they are used as intended and under the conditions specified by the manufacturer. This document applies to: -? gas distribution system, beginning in the direction of flow with the manually isolation main shut-off valve at the inlet of the thermoprocessing equipment; -? burner, burner assembly and ignition devices, open firing; -? Safety control system (protective system). This document is applicable to all types of combustion of fuel gases with atmospheric air, compressed air or oxygen. This document also includes necessary requirements for user information. This document does not apply to manual burners, systems for flame spraying and micro soldering torches. This document does not apply to systems for welding, cutting and associated processes using plasma and laser technology. This document does not cover the hazards arising as a result of the release of flammable substances from the products processed in the IThE. This document is not applicable to electrical wiring and heavy-current wiring connected upstream of the IThE control cabinet/control panel/protective system. Noise and optical radiation can cause significant hazards when using gas welding equipment. These are not covered in this document. This document is not applicable to oxy-fuel IThE, associated gas supply systems and protective systems manufactured before the date of publication of this document in the Official Journal of the EU.

This draft European standard is applicable to the physical and link layer parameters of baseband communication over twisted pair (M Bus) for meter communication systems. It is especially applicable to thermal energy meters, heat cost allocators, water meters and gas meters. NOTE It is usable also for other meters (like electricity meters) and for sensors and actuators. For generic descriptions concerning communication systems for meters and remote reading of meters see EN 13757-1.

This document specifies methods for qualifying an environment that approximates to an acoustic free field near one or more reflecting planes. The goal of the qualification is to determine the environmental correction K2, which is used to correct for reflected sound when determining the sound power level or sound energy level of a noise source from sound pressure levels measured on a surface enveloping the noise source (machinery or equipment) in such an environment. In addition, the environmental correction K2  is used as an input parameter for the determination of the local environmental correction K3 which is used to determine the emission sound pressure level in an environment that approximates to an acoustic free field near one or more reflecting planes. In practice, the K2  value determined will be a function of both the reflected sound from the test environment and the shape and size of the measurement surface used for the K2 determination. For the purposes of this standard and the standards that refer to it, the differences between K2  values determined with different measurement surfaces are assumed to be included in the stated measurement uncertainty for the test method.

This document specifies the composition, mechanical properties and other relevant characteristics of copper and copper alloys. The sampling procedures and test methods for the verification of conformity to the requirements of this document are also specified. This document is applicable to: a) copper alloy ingots intended to be remelted for later processing (e.g. castings); and b) copper and copper alloy castings which are intended for use without subsequent working other than machining. Recommended practice for the ordering and supply of castings is included in Annex A. Optional supplementary inspection procedures for ingots and castings are included in Annex B. NOTE Ingots are not suitable for pressure equipment applications.

This document specifies a test method for the determination of the opening, closing and running torque of thermoplastics valves. This test is considered to be performed as part of the initial type testing. This document applies to all types of thermoplastics valves intended to be used for the transport of fluids. NOTE 1 Examples of valve types tested with this method are in ISO 16135, ISO 16136, ISO 16138, ISO 16139, ISO 21787, ISO 4437-4, ISO 16486-4, EN 12201-4, EN 1555-4. It does not specify the relationship between the torque and its possible increase after valve prolonged use at specific working condition or materials wear/chemical aggression. NOTE 2 Concerning the chemical aggression of the materials, a collection of data is reported in ISO/TR 10358; concerning the endurance test necessary to confirm the ability of hand-operated plastics valves to withstand prolonged use with repeated opening and closure, further information is provided in ISO 8659.

This document specifies three test methods for investigating brazeability. A spreading test shows testing method with measurement of the spread area of the filler metals. A T-joint test describes a scheme to construct a T-shape design by the test pieces and a testing method. A varying gap test describes a test piece and a testing method for assessing the influence of the various parameters which can influence brazing during manufacture as a function of clearances.
