This International Standard specifies a general method for determining the average molecular mass and molecular mass distribution of polymers (see Reference) from 2 000 g ⋅ mol−1 to 20 000 g ⋅ mol−1 by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS).
The average molecular masses and molecular mass distributions are calculated from a calibration curve constructed using synthetic-polymer and/or biopolymer standards. This method is therefore classified as a relative method.
The method is not applicable to polyolefins or to polymers with a polydispersity > 1,2.
This document specifies the particular requirements for the clinical investigations of intraocular lenses that are to be implanted in the eye in order to correct aphakia.
This PAS specifies requirements for the collaborative sharing of structured health and safety information throughout the project life-cycle.
The PAS supports the development of structured health and safety (H&S) data for all projects progressively from the outset.
The PAS provides guidance on how H&S information is generated, flows and can be used throughout the project and asset lifecycle. Whilst all H&S risk information can be included within an information model, this PAS requires the contextualization and filtering of hazards and risks to prioritize the significant risks.
The PAS sets out a model for the application of H&S data and information-use through BIM processes and applications. The principles and requirements of this PAS can be applied equally to non-BIM projects.
The PAS specifies how to use H&S information in order to:
a) provide a safer and healthier environment for end-users;
b) mitigate the inherent hazards and risks across the whole project lifecycle;
c) result in improved construction safety performance, less incidents and associated impacts;
d) provide for clearer, more assured and relevant health and safety information to the ‘right-people’ at the ‘right time’;
e) reduce construction and operational costs.
The exchange and use of H&S information is intended to support:
1) representation of the nature and characteristics of the project, site and built asset;
2) representation of H&S hazards, risks and associated factors;
3) the generalization, dissemination and re-use of H&S knowledge and experience.
The PAS is applicable to individuals and organizations that contribute to and influence the definition of design, construction, operation (use) and end of life of a built asset.
This PAS does not define or change the duties set out in any relevant statutory provisions.
This PAS can be applied in conjunction with the duty holder’s own management systems policies and arrangements.
This PAS describes a method for testing the performance of a single bollard, when subjected to a single impact using a 2 500 kg impact trolley at a speed of 16 km/h or 32 km/h.
PAS 170-1 does not cover testing the performance of blockers, planters or street furniture.
It is not equivalent to a full-scale vehicle impact test method. It does not cover the performance of a test item or its control apparatus when subjected to: blast explosion, ballistic impact, manual attack with the aid of tools or electrical manipulation/attack through a control system.
This PAS is for use by manufacturers, distributers or specifiers of bollards.
NOTE Full-scale vehicle impact test method is defined in 3.7.

This International Standard defines the essential technical requirements that must be addressed in the process of design and construction of Generation IV (GEN IV) nuclear reactors. It does not address operation, maintenance and in-service inspection of reactors.
Six reactor concepts are considered for GEN IV:
The Sodium Fast Reactor, The Lead Fast Reactor, The Gas Fast Reactor, The Very High Temperature Reactor, The SuperCritical Water Reactor and the Molten Salt Reactor.
Annex A details the main characteristics for the different concepts.
The scope of application of the standard is limited to mechanical components related to nuclear safety and to the prevention of the release of radioactive materials:
— that are considered to be important in terms of nuclear safety and operability, and
— that play a role in ensuring leaktightness, partitioning, guiding, securing and supporting,
— that contain and/or are in contact with fluids (such as vessels, pumps, valves, pipes, bellows, box structures, heat exchangers, handling and driving mechanisms).
This International Standard gives design, construction, type and production testing, and marking requirements for non-insulated cryogenic flexible hoses used for the transfer of cryogenic fluids within the following range of operating conditions:
— working temperature: from − 270 °C to + 65 °C;
— nominal size (DN): from 10 to 100.
End fittings for mounting of any couplings are within the scope of this International Standard, but the couplings are subject to other standards.
It is intended that the hose be designed and tested to satisfy the generally accepted rated pressure i.e. at least PR 40. Hoses may be then selected with a PR equal to or greater than the maximum allowable pressure (PS) of the equipment to which it is to be used.
This standard specifies requirements and test methods for sterile urethral catheters for single use, with or without a balloon.

This part of ISO 21970 specifies the methods of preparation of test specimens and the standard test methods to be used in determining the properties of thermoplastic polyketone moulding and extrusion materials. Requirements for handling test material and/or conditioning both the test material before moulding and the specimens before testing are given.
Procedures and conditions for the preparation of test specimens in a specified state and procedures for measuring properties of the test materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize polyketone moulding and extrusion materials are listed.
The properties have been selected from the general test methods in, ISO 10350‑1. Other test methods in wide use for or of particular significance to these moulding and extrusion materials are also included in this part of ISO 21970, as are the designatory properties specified in part 1.
In order to obtain reproducible and comparable test results, it is necessary to use the methods of preparation and conditioning, the specimen dimensions and the test procedures specified in this part of ISO 21970. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.
Background noise exists ubiquitously in analytical instruments, whether or not a sample is applied to the instrument. This document is concerned with mathematical methodologies for estimating the minimum detectable value in case that the most predominant source of measurement uncertainty is background noise. The minimum detectable value can directly and mathematically be derived from the stochastic characteristics of the background noise.
This document specifies basic methods to
— extract the stochastic properties of the background noise,
— use the stochastic properties to estimate the standard deviation (SD) or coefficient of variation (CV) of the response variable, and
— calculate the minimum detectable value based on the SD or CV obtained above.
The methods described in this document are useful for checking the detection of a certain substance by various types of measurement equipment in which the background noise of the instrumental output predominates over the other sources of measurement uncertainty. Feasible choices are visible and ultraviolet absorption spectrometry, atomic absorption spectrometry, atomic fluorescence spectrometry, luminescence spectrometry, liquid chromatography and gas chromatography.
This document defines the basic terms relating to the design and operation of Reciprocating Internal Combustion (RIC) engines.

However, other criteria might also apply, such as surface temperatures, temperature rise of surroundings, appliance stability, etc., and these have to be taken into account in the method of installation.
NOTE 1 For the purposes of this standard, installation includes design, inspection and commissioning. It is recognized that each of these tasks can at times be performed by the same persons.
NOTE 2 As well as normally constructed dwellings, domestic premises include any permanently sited leisure accommodation vehicles, residential park homes and permanently moored boats. Particular and additional requirements exist for the supply of gas to these categories of premises and can be found in IGEM/G/6 . Neither this standard nor IGEM/G/6  applies to gas installations in towed or motorized caravans.
NOTE 3 Where domestic cooking appliances are installed in commercial or industrial premises in conjunction with catering appliances, reference should be made to BS 6173, particularly with regard to ventilation and extraction.
NOTE 4 For commercial premises that are primarily domestic premises, e.g. a small bed and breakfast premises, the general rules of BS 6173 do not apply except with respect to hygiene and general safety.
This British Standard specifies requirements for eight classes of petroleum fuels for engines and boilers used in agricultural, domestic and industrial applications.
This British Standard does not preclude lawful use of one class of fuel in an application designed for use with a fuel of another class. However, it is strongly recommended that only class C1 burner fuel is used in flueless domestic appliances, and it is advisable that tests or consultation with the equipment manufacturer are carried out if fuel is to be used for a purpose other than that for which it is classified in this British Standard.
NOTE Annex A, Annex B and Annex C provide information on fuel types and applications, storage and handling, and properties of fuels respectively. Additional information on storage and handling is given in BS 6380.
This part of BS 5306 gives recommendations for the initial commissioning of portable fire extinguishers and schedules for the subsequent maintenance of extinguishers installed in all locations.
