ISO 17208 -sarja kuvaa menettelyt, joilla mitataan tutkittavan aluksen säteilemää vedenalaista ääntä sekä lasketaan mittaustuloksista äänilähdettä kuvaavia suureita, kuten lähdetaso ja säteillyn melun taso.Standardeissa ISO 17208-1...3 oletetaan, että tutkittava alus osallistuu mittauksiin yhteistyössä suorittamalla useita ajoja määrättyä reittiä pitkin mittausjärjestelmän ohi ennalta määritellyllä nopeudella ja koneistokokoonpanolla. Ohi kulkevien alusten säteilemän äänen opportunistiset mittaukset eivät kuulu näiden kolmen standardin soveltamisalaan.ISO 17208 -standardisarjan osa 1[1] esittää menettelyn aluksen vedenalaisen äänen määrittämiseksi sen säteillyn melun tasona. Tämä lasketaan aluksen kaukokentässä, sivukulmassa mitatusta äänenpainetasosta (SPL), joka skaalataan lähimmän ohitusetäisyyden (CPA) mukaan ja raportoidaan desidekadikaistoin. Säteillyn melun tason käyttötarkoituksena on osoittaa sopimusvaatimusten tai kriteerien täyttyminen, mahdollistaa eri alusten vertailu, tukea alusten akustisen tunnuskuvan säännöllistä arviointia sekä palvella tutkimus- ja kehitystyötä.ISO 17208-2[1] määrittelee menetelmät, joilla standardin ISO 17208-1 mukaisesti saaduista säteillyn melun tason arvoista lasketaan määritellyllä nimellisellä lähdesyvyydellä sijaitsevan ekvivalentin monopoliäänilähteen lähdetaso. Lähdetason ja siihen liittyvän nimellisen lähdesyvyyden käyttötarkoituksena on mahdollistaa kaukokentän äänen etenemisen ennustaminen esimerkiksi ympäristövaikutustutkimuksia tai vedenalaisten melukarttojen laatimista varten.ISO 17208-1 ja ISO 17208-2[1] soveltuvat syvän veden mittauksiin, joissa veden syvyys on suurempi kuin arvoista 150 m ja 1,5 kertaa aluksen kokonaispituus suurempi. Osan 3 mukaisten mittausten sallitut veden syvyydet ja ympäristöolosuhteet on kuvattu kohdassa 4.5.Tässä asiakirjassa määritellään menettelyt tutkittavan aluksen säteilemän vedenalaisen äänen mittaamiseksi matalassa vedessä. Lisäksi siinä määritellään menetelmät, joilla äänenpainemittauksista lasketaan lähdetaso siihen liittyvine nimellisine lähdesyvyyksineen ottaen huomioon ne ilmiöt, jotka hallitsevat äänen etenemistä matalassa vedessä. Nämä laskentamenetelmät on kuvattu kohdassa 7. Kun lähdetaso on laskettu, siitä ja lähdesyvyydestä voidaan johtaa myös muita mittareita. Kohdassa 7.3 esitetään menettely sellaisen säteillyn melun tason laskemiseksi, joka olisi mitattu syvässä vedessä standardin ISO 17208-1 mukaisesti samalla aluksella ja samoissa käyttöolosuhteissa.

ISO 21439:2009 määrittelee menetelmät vedessä tai kudoksessa esiintyvien absorboituneen annoksen jakaumien määrittämiseksi ennen silmäkasvainten hoitoon tarkoitetun beetasäteilyn sekä suonensisäisen brakyterapian käyttöä. Standardissa esitetään suosituksia beetasäteilylähteiden kalibrointiin, dosimetrisiin mittauksiin, annoslaskentaan, dosimetriseen laadunvarmistukseen sekä beetasäteilyyn perustuvan brakyterapian hoitosuunnitteluun. Lisäksi annetaan ohjeita veteen absorboituneen annoksen epävarmuuden arviointiin. ISO 21439:2009 soveltuu "suljettuihin" radioaktiivisiin lähteisiin, kuten tasomaisiin ja koveriin pintalähteisiin, yksittäisistä siemenlähteistä muodostuviin lähdeketjuihin, viivalähteisiin sekä kuori- ja tilavuuslähteisiin, joissa ainoastaan emittoituvalla beetasäteilyllä on hoidollista merkitystä.Standardissa kuvattujen kliinisen dosimetrian menettelyjen standardointi muodostaa perustan beetasäteilyyn perustuvan brakyterapian luotettavalle käytölle. Standardissa esitetyt erityiset dosimetriset menetelmät soveltuvat silmäsairauksien parantavaan hoitoon tarkoitettuihin lähteisiin, suonensisäiseen brakyterapiaan, verisuonen uudelleenahtauman ehkäisyyn sekä muihin beetasäteilyä hyödyntäviin kliinisiin sovelluksiin.ISO 21439:2009 on tarkoitettu organisaatioille, jotka haluavat ottaa käyttöön dosimetrian vertailumenetelmiä ja pyrkivät täyttämään kliiniset vaatimukset siten, että potilaalle annettavan säteilyannoksen epävarmuus pysyy riittävän pienenä. Standardi ei kuitenkaan sulje pois mahdollisuutta käyttää muitakin menetelmiä, joilla voidaan saavuttaa sama tai jopa pienempi mittausepävarmuus.

(Intermodal and Short Sea Shipping)
Alkuperä: ISO
Määräpäivä: 2026-10-02
This document defines events and associated information elements that are used for tracking and tracing of all types of cargo in the maritime domain. This does not include passengers or crew.
The document also defines information exchanges and information elements based on the ISO 28005 framework.
The document is an elaboration of the UNECE “Business Requirements Specification for Integrated Track and Trace for Multi-Modal Transportation” with its inherent assumptions, which are:
All transportation is related to a trade transaction between a seller and a buyer of goods that results in one or more shipments. Therefore, all tracking and tracing and events described in this document ultimately also “link” with these shipments.
There is no present need for additional data identifiers to facilitate multi-modal tracking and tracing of trade shipments or the linked transportation in scope for this document. See below this bullet list.
Identifiers for trade items, cargo, their packaging or container, or means of transport will support multi-modal tracking and tracing, if the identifiers are globally unique.
Linkages can be made between the different identifiers using various existing technologies.
The model supports tracking and tracing using various existing technologies by using the most relevant waypoints for the transport journey (as agreed among stakeholders).
Standardized exchange processes may be used, without the need to create new class diagrams or new message structures.
The operational scope covers the voyage of the ship, via the terminal, up to and including the gate-in event or gate-out event in the terminal. Gate-in and gate-out events include transfers between the maritime terminal and hinterland modes of transport such as road vehicles, feeder ships, inland waterway barges or rail wagons. The document aims to cover all kinds of cargoes carried on maritime ships.
Cargo moves through ports in two main directions:
Coming in from sea to be transported to destinations in the hinterland of the port.
Coming in from the hinterland to be transported to overseas destinations on maritime ships.
For the purposes of this document, we will ignore the transshipment scenario where the cargo comes in on maritime ships and also leaves on maritime ships from and to destinations that are not considered part of the hinterland of the port.
The supply chain events that occur outside the boundaries of gate in and gate out mentioned above are not in scope for this document. It is recognised that the transport-related operations covered in the scope of this document are an integral part of the end-to-end supply chain between seller and buyer. Therefore, the requirements outlined in this document will follow standards and "best practices" already in use in the supply chain. This is also driven by the fact that there are critical hand-overs between the wider supply chain and the operations in scope for this document at the gate in and gate out processes that require unambiguous exchange of information related to the critical events in those processes.

1.1 This document specifies the constructional requirements for fans constructed to Group II G (of explosion groups IIA, IIB and hydrogen) categories 1, 2 and 3, and Group II D categories 2 and 3, intended for use in explosive atmospheres.
NOTE 1 Operation conditions for the different categories of fans used in this document are defined in Clause 4.
1.3 This document specifies requirements for design, construction, testing and marking of complete fan units intended for use in potentially explosive atmospheres in air containing gas, vapour, mist and/or dusts. Such atmospheres can exist inside (the conveyed atmosphere (flammable or not)), outside, or inside and outside of the fan.
This document covers mechanical equipment, in particular fans. The “type of protection” as specified in EN ISO 80079 37:2016 is constructional safety.
1.4 This document is applicable to fans working in ambient atmospheres and with normal atmospheric conditions at the inlet, having
— absolute pressures ranging from 0,8 bar to 1,1 bar,
— and temperatures ranging from -20 °C to +60 °C,
— and maximum volume fraction of 21 % oxygen content,
— and an aerodynamic energy increase of less than 25 kJ/kg.
NOTE 1 25 kJ/kg is equivalent to 30 kPa at inlet density of 1,2 kg/m3.
This document can also be helpful for the design, construction, testing and marking of fans intended for use in atmospheres outside the validity range stated above or in cases where other material pairings need to be used. In this case, the ignition risk assessment, ignition protection provided, additional testing (if necessary), manufacturer's marking, technical documentation and instructions to the user, clearly demonstrate and indicate the equipment's suitability for the conditions the fan can encounter.
NOTE 2 Temperatures below -20 °C can be considered. Material suitability can require specific evaluation for these temperatures. With lower temperature the explosion pressure increases, which leads to increased test pressures (see A.3) and can require specific testing. Although the standard atmospheric conditions in EN ISO 80079 36:2016 give a temperature range for the atmosphere of -20 °C to +60 °C the normal ambient temperature range for the equipment is -20 °C to +40 °C unless otherwise specified and marked.
