Space systems — Failure reporting, analysis, and corrective action (FRACA) process requirements
This project proposes the development of a new International Standard that defines Failure Reporting, Analysis, and Corrective Action (FRACA) process requirements. This new International Standard will require an organization, group, or individual to apply a closed-loop FRACA process that is capable of effectively managing the failure risks and issues associated with its products. In addition,…
Magnetic fusion facilities — Requirements for the safety systems raised by the application of the su...
The proposal will cover following aspects:
- Requirements on penetrations through vacuum vessel, cryostat and building walls. They serve as different level of confinement systems. Superconducting magnets are located between the vacuum vessel and cryostat with the auxiliary systems connecting the magnets with power and coolant supply outside the main building.
- Requirements on the shielding…
Determination of sustained combustibility of liquids
This document specifies a procedure, at temperatures up to 100 °C, to determine whether a liquid product, that would be classified as “flammable” by virtue of its flash point, sustains combustion at the temperature(s) specified e.g. in regulations.
NOTE Many national and international regulations classify liquids as presenting a flammable hazard based on their flash point, as determined by…
ISO 28079:2009 specifies a method for measuring the Palmqvist toughness of hardmetals and cermets at room temperature by an indentation method. ISO 28079:2009 applies to a measurement of toughness, called Palmqvist toughness, calculated from the total length of cracks emanating from the corners of a Vickers hardness indentation, and it is intended for use with metal-bonded carbides and…
Implants for surgery — Materials — Simulated body fluid (SBF) preparation procedure and test method ...
This document specifies a procedure for preparing the simulated body fluid (SBF) and a test method for use as an initial screening tool in the evaluation of apatite formation on the surfaces of bone-contacting implant materials.
The results of this SBF test (see Clause 7) alone do not establish bone-bonding ability. The test can be used along with other in vitro and in vivo confirmatory tests to…
Polyphenylsulphone (PPSU) — Effect of time and temperature on expected strength
This document specifies the minimum values for expected strength as a function of time and temperature in the form of reference lines, for use in calculations on Polyphenylsulfone (PPSU) injection moulded piping components.
Reaction to fire tests — Parallel panel test method for wall systems — Measurement of heat release a...
This standard will specify a large-scale fire test method for measuring the heat release rates (HRR) and the smoke-production rates (SPR) of wall systems. The fire scenario covered in this document is representative of severe fires originating in near wall or corner locations of an exterior or interior wall construction. Severe fire exposure to wall systems, on the order of 100 kW/m2 heat flux,…
