In the conditions given above, it is recommended that the hoses and hose assemblies be protected by shields wherever possible. Where the installation involves severe bends or where the fixing points are in different planes, the use or formed (shaped) hose should be considered. Hoses installed at bend radii less than…

Frames are defined as the foi’mat of data iackets on the wire. The Internet Protocol (lPv4) theoretically allows for a maximum IP packet length of 64 Khytes. This size is limited by the Ethernet specification, which defines a 16-bit-length field and requires a minimum packet length of64 bytes, as well as allowing for a maximum payload length of 1 500 bytes. Consequently, IP packets can have a maximum length of only 1 500 bytes on Ethernet. Howevei IP allows for fragmentation of IP packets over multiple Ethernet frames to work around this limitation. The rules for fragmentation of IP packets differ between IPv6 and lPv4 and are not specified in this document. The Ethernet connection of a…

  • ISO 13909-5:2016 pdf free download.Hard coal and coke Mechanical sampling Part 5:Coke Sampling from moving streams Houlile et coke — Echantillonnage mécanique — Partie 5: Coke — Echantillonnage en continu. Under some conditions, e.g. high ambient temperature, increments which are smaller than those corresponding to the design capacity of the system may suffer from disproportionate changes in quality, e.g. loss in moisture, and precautions need to be taken to prevent this. If such losses cannot be prevented and are found to cause bias, such means as buffer hoppers shall be used. Alternatively, increments can themselves be retained temporarily in a buffer hopper until there is sufficient mass to ensure passage, without introducing bias into the system, through an on-line preparation system. On no account shall a primary sampler be switched off at low flow rates to avoid low mass increments. When measuring primary increment variance (see ISO 13909-7:20 16, Clause 6) at preliminary stages in the design of the sampling scheme, use increment masses that are close to those expected to be taken by the system, based on similar coke from similar sampling systems. After implementation of the sampling scheme, the precision of the result can be estimated and adjusted…
