This part of ISO 19901 provides requirements, guidance, and information for the design and, fabrication of topsides structure for offshore structures. It complements ISO 19902, ISO 19903, ISO 19904-1,
ISO 19905-1 and ISO 19906, which provide requirements for various forms of substructure.
The actions on topsides structure, and the action effects in the structural components are derived from this part of ISO 19901, where necessary in combination with other International Standards in the ISO 19901 series.
The resistances of non-cylindrical structural components of the topsides structure can be determined by the use of national building standards, as specified in this part of ISO 19901.
The resistance of cylindrical structural components are to be in accordance with ISO 19902 but may be according to national building standards, as specified in this part of ISO 19901.
This part of ISO 19901 is applicable to the following:
— topsides of fixed offshore structures;
— discrete structural units placed on the hull structures of floating offshore structures and mobile offshore units;
— topsides of arctic offshore structures, excluding winterization ( ISO 19906).
If any part of the topsides structure forms part of the primary structure of the overall structural system which resists global platform actions, the requirements of this part of ISO 19901 are supplemented with applicable requirements in ISO 19902, ISO 19903, ISO 19904-1, ISO 19905-1 and ISO 19906.
This part of ISO 19901 does not apply to those aspects of topsides structure that form part of the overall structural system of floating offshore structures and mobile offshore units that are governed by the rules of a recognized certifying authority and which are within class rules.
The fire and explosion provisions of this part of ISO 19901 can however be applied to those parts of the hulls of floating offshore structures and mobile offshore units that contain hydrocarbon processing, piping or storage.
This part of ISO 19901 addresses the following aspects of topsides structure:
— design, fabrication, installation and modification;
— prevention, control and assessment of fire, explosions and other accidental events.
NOTE Requirements for structural integrity management are presented in ISO 19901-9.
This part of ISO 19901 applies to structural components including the following:
— primary and secondary structure in decks, module support frames and modules;
— flare structures;

— crane pedestal and other crane support arrangements;
— helicopter landing decks (helidecks);
— permanent bridges between separate offshore structures;
— masts, towers and booms on offshore structures.

The primary purpose of this document is to provide minimum acceptable criteria required to establish a procedure for retrospective dosimetry by electron paramagnetic resonance spectroscopy and to report the results.
The second purpose is to facilitate the comparison of measurements related to absorbed dose estimation obtained in different laboratories.
This document covers the determination of absorbed dose in the measured material. It does not cover the calculation of dose to organs or to the body. It covers measurements in both biological and inanimate samples, and specifically:
a) based on inanimate environmental materials like glass, plastics, clothing fabrics, saccharides, etc., usually made at X-band microwave frequencies (8 GHz to 12 GHz);
b) in vitro tooth enamel using concentrated enamel in a sample tube, usually employing X-band frequency, but higher frequencies are also being considered;
c) in vivo tooth dosimetry, currently using L-band (1 GHz to 2 GHz), but higher frequencies are also being considered;
d) in vitro nail dosimetry using nail clippings measured principally at X-band, but higher frequencies are also being considered;
e) in vivo nail dosimetry with the measurements made at X-band on the intact finger or toe;
f) in vitro measurements of bone, usually employing X-band frequency, but higher frequencies are also being considered.
For biological samples, in vitro measurements are carried out in samples after their removal from the person or animal and under laboratory conditions, whereas the measurements in vivo are carried out without sample removal and may take place under field conditions.
NOTE The dose referred to in this document is the absorbed dose of ionizing radiation in the measured materials.

The purpose of this document is to provide minimum criteria required for quality assurance and quality control, evaluation of the performance and to facilitate the comparison of measurements related to absorbed dose estimation obtained in different laboratories applying ex vivo X-band EPR spectroscopy with human tooth enamel.
This document covers the determination of absorbed dose in tooth enamel (hydroxyapatite). It does not cover the calculation of dose to organs or to the body.
This document addresses:
a) responsibilities of the customer and laboratory;
b) confidentiality and ethical considerations;
c) laboratory safety requirements;
d) the measurement apparatus;
e) preparation of samples;
f) measurement of samples and EPR signal evaluation;
g) calibration of EPR dose response;
h) dose uncertainty and performance test;
i) quality assurance and control.

This document focuses on monitoring the activity concentrations of radioactive gases. They allow the calculation of the activity releases, in the gaseous effluent discharge from facilities producing positron emitting radionuclides and radiopharmaceuticals. Such facilities produce short-lived radionuclides used for medical purposes or research and can release gases typically including, but not limited to 18F, 11C, 15O and 13N. These facilities include accelerators, radiopharmacies, hospitals and universities. This document provides performance‑based criteria for the design and use of air monitoring equipment including probes, transport lines, sample monitoring instruments, and gas flow measuring methods. This document also provides information on monitoring program objectives, quality assurance, development of air monitoring control action levels, system optimisation and system performance verification.
The goal of achieving an unbiased measurement is accomplished either by direct (in-line) measurement on the exhaust stream or with samples extracted from the exhaust stream (bypass), provided that the radioactive gases are well mixed in the airstream. This document sets forth performance criteria and recommendations to assist in obtaining valid measurements.
NOTE 1 The criteria and recommendations of this document are aimed at monitoring which is conducted for regulatory compliance and system control. If existing air monitoring systems were not designed according to the performance criteria and recommendations of this document, an evaluation of the performance of the system is advised. If deficiencies are discovered based on a performance evaluation, a determination of the need for a system retrofit is to be made and corrective actions adopted where practicable.
NOTE 2 The criteria and recommendations of this document apply under both normal and off‑normal operating conditions, provided that these conditions do not include production of aerosols or vapours. If the normal and/or off-normal conditions produce aerosols and vapours, then the aerosol collection principles of ISO 2889 also apply.

This document specifies minimum nuclear criticality safety training requirements for operations staff, operations supervisors, and management.
This document is applicable to areas, processes or facilities containing quantities of fissile material for which nuclear criticality safety assessment is required as defined in ISO 1709.
This document is not applicable to the transport of fissile materials outside the boundaries of nuclear establishments.

This document specifies the characteristics of reference measurement standards of radioactive surface contamination, traceable to national measurement standards, for the calibration of surface contamination monitors. This document relates to alpha-emitters, beta-emitters, and photon emitters of maximum photon energy not greater than 1,5 MeV.
It does not describe the procedures involved in the use of these reference measurement standards for the calibration of surface contamination monitors. Such procedures are specified in IEC 60325[6], IEC 62363[7], and other documents.
NOTE Since some of the proposed photon standards include filters, the photon standards are to be regarded as reference measurement standards of photons of a particular energy range and not as reference measurement standards of a particular radionuclide. For example, a 241Am source with the recommended filtration does not emit from the surface the alpha particles or characteristic low-energy L X-ray photons associated with the decay of the nuclide. It is designed to be a reference measurement standard that emits photons with an average energy of approximately 60 keV.
This document also specifies preferred reference radiations for the calibration of surface contamination monitors. These reference radiations are realized in the form of adequately characterized large area sources specified, without exception, in terms of surface emission rate and activity which are traceable to national standards.

This document specifies the different leakage test methods for sealed sources. It gives a comprehensive set of procedures using radioactive and non-radioactive means.
This document applies to the following situations:
— leakage testing of test sources following design classification testing in accordance with ISO 2919[1];
— production quality control testing of sealed sources;
— periodic inspections of the sealed sources performed at regular intervals, during the working life.
Annex A of this document gives guidance to the user in the choice of the most suitable method(s) according to situation and source type.
It is recognized that there can be circumstances where special tests, not described in this document, are required.
It is emphasized, however, that insofar as production, use, storage and transport of sealed radioactive sources are concerned, compliance with this document is no substitute for complying with the requirements of the relevant IAEA regulations[17] and other relevant national regulations. It is also recognized that countries can enact statutory regulations which specify exemptions for tests, according to sealed source type, design, working environment, and activity (e.g., for very low activity reference sources where the total activity is less than the leakage test limit)

This International Standard provides requirements and guidance regarding the use of CAAS for operations. Requirements and guidance on CAAS design are provided in the IEC 60860:2014.
This International Standard is applicable to operations with fissile materials outside nuclear reactors but within the boundaries of nuclear establishments.
This International Standard applies when a need for CAAS has been established. As a consequence, the need for CAAS is not covered by this International Standard but information about the need for CAAS is
given in annex C.
This International Standard does not include details of administrative steps, which are considered as prerogatives of the management system (ISO 14943 provides details of administrative steps).
Details of nuclear accident dosimetry and personnel exposure evaluations are not within the scope of this International Standard.
This International Standard is concerned with gamma and neutron radiation rate-sensing systems.
Specific detection criteria can be met with integrating systems or with systems detecting either neutron or gamma radiation, and analogous considerations apply.

This standard provides the specification of the Common Distributed Application Protocol (CDAP).
CDAP enables distributed applications to deal with communications at an object level, rather than
forcing applications to explicitly deal with serialization and input/output operations. CDAP provides
the application protocol component of a Distributed Application Facility (DAF).[3] CDAP provides
a straightforward and unifying approach to sharing data over a network without having to create
specialized protocols. This standard describes the following: an overview of CDAP; the specification
of CDAP; a description of policies, in the specific sense introduced in the text; and some notes on CDAP
context.

This document specifies requirements and test methods for evaluation of the permanence and
durability of writing, printing, and copying on paper stored in libraries, archives, and other protected
environments for long periods of time, in which the information contents of images must be retained
but not necessarily the full artistic quality.
It is applicable to:
— images on white permanent paper in accordance with ISO 9706 or ISO 11108;
— recording obtained from pens, stamp pads, copying machines and printers (that can produce
monocoloured and/or multicoloured images)
It does not apply to:
— documents stored under harmful conditions, such as high humidity that promotes microbiological
attack, excessive heat, radiation (e.g. light), high levels of pollutants, or the influence of water.
Since documents are kept in non-protected environments before being transferred to protected
environments, resistance to water and light is, however, of importance;
— legal documentation, e.g. banking documents, where the authenticity is of primary interest;
— documents where the information contents are influenced by small colour changes;
— documents within the scope of ISO/TC 42, Photography.

This standard provides a method for evaluating the resonance vibration frequency of multi-copter UA
only. The frequency of the rotor means the frequency within the operating frequency range, and the
frequency of the main body means the global mode frequency. This standard specifies a method to
avoid design of UA that the resonance occurs generated by the coincidence of the natural frequency of
the UA body and the rotational frequency of the rotor.
This standard relates to multi-copter UA weighing less than 150kg.

This PAS gives guidance on establishing a decision-making framework for sharing
data and information services in smart cities.
It covers:
a) types of data in smart cities;
b) establishing a data sharing culture;
c) data value chain – roles and responsibilities;
d) purposes for data use;
e) assessing data states;
f) defining access rights for data; and
g) data formats/format of transportation.
This PAS aims to support the sharing of data and information services within
cities. For some cities there will also be a need to establish specific data sharing
agreements, particularly where data is being shared by multiple organizations
at once.
This PAS supports a transparent approach to making decisions and creating
specific data sharing agreements in order to fully realise the benefits and value
of data and information services in a city.
Missing data or misinterpretation of data can lead to the wrong actions being
taken by city decision-makers. A decision-making framework for sharing data can
help ensure that they have the best overall data on which to base decisions.
This PAS does not cover:
a) national security issues;
b) good practice for use of data by the citizen;
c) existing interoperability agreements between cities;
d) defining application programming interfaces (API) networks; or
e) any data sharing rules and regulations specific to a particular jurisdiction.
It is assumed that a security-minded approach to data sharing is used by cities.
NOTE 1 Requirements on establishing and implementing a security-minded approach
to data sharing are specified in PAS 185 (in preparation).
NOTE 2 Further details on the areas not covered in this PAS, including information on
relevant standards publications, are given in Annex A.
This PAS is for use by decision-makers in smart cities from the public, private and
third sectors. It is also of interest to any city organization wishing to share data.
