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…

1 Scope 1.1 This Standard describes methods for determining the occupational noise exposure level of workers (Lex,T) using sampling techniques. Lex,T represents the long-term noise exposure of workers and is calculated from measurements of Leq,t (3 dB exchange rate) in the workplace. Notes: 1) The methods in this Standard are based on established definitions, units, instrumentation, and…

1 Scope This part of ISO/IEC 14776 defines the command set extensions to facilitate operation of SCSI direct access block devices. The clauses in this standard, implemented in conjunction with the applicable clauses of SPC-4, specify the standard command set for SCSI direct access block devices. The objectives of this standard are to: a) permit an application client to communicate over a…

1 Scope and object This part of IEC 61215 lays down IEC requirements for the design qualification and type approval of terrestrial photovoltaic modules suitable for long-term operation in general open air climates, as defined in IEC 60721-2-1. This standard is intended to apply to all crystalline silicon terrestrial flat plate modules. This standard does not apply to modules used with…

1 Scope and object This part of IEC 61215 lays down IEC requirements for the design qualification and type approval of terrestrial photovoltaic (PV) modules suitable for long-term operation in general open-air climates, as defined in IEC 60721-2-1. This standard is intended to apply to all terrestrial flat plate module materials such as crystalline silicon module types as well as thinfilm…

1 Scope and object This International Standard series lays down IEC requirements for the design qualification and type approval of terrestrial photovoltaic modules suitable for long-term operation in general open-air climates, as defined in IEC 60721-2-1. This part of IEC 61215 is intended to apply to all terrestrial flat plate module materials such as crystalline silicon module types as well…

This National Standard of Canada applies to two types of automotive fuel: type 1, 50% to 85% by volume denatured fuel ethanol with gasoline and type 2, 20% to 25% by volume denatured fuel ethanol with gasoline. Both types are strictly for use in flexible-fuel vehicles over a wide range of climatic conditions. Users of this standard are advised to consult the owner’s manual and/or the original…

1 Scope This Recommendation | International Standard establishes control objectives, controls and guidelines for implementing controls, to meet the requirements identified by a risk and impact assessment related to the protection of personally identifiable information (PII). In particular, this Recommendation | International Standard specifies guidelines based on ISO/IEC 27002, taking into…

1 Scope This Recommendation | International Standard provides guidance on concepts and principles for the governance of information security, by which organisations can evaluate, direct, monitor and communicate the information security related activities within the organisation. This International Standard is applicable to all types and sizes of organisations

1 Scope This document establishes: — principles and methods for performance assessment of presentation attack detection mechanisms; — reporting of testing results from evaluations of presentation attack detection mechanisms; — a classification of known attack types (in an informative annex). Outside the scope are: — standardization of specific PAD mechanisms; — detailed information about…
