1 Scope 1.1 This test method evaluates the temperature transmission performance of an encapsulation material or assembly of materials installed over a wood substrate when the test specimen is subjected to a standard fire exposure condition following the standard time-temperature curve as described in Section 6 (Test Conditions). 1.2 It is the intent that the encapsulation period…

1 Scope 1.1 This Standard covers the principles governing the design and application of visual components used to create a safety way guidance system (SWGS) and requirements for the installation, inspection, testing and maintenance of SWGS. 1.2 This Standard contains general principles valid both for electrically powered and for photoluminescent components. Special information which is…

This document defines the message, data structures, and data elements to support exchanges between the roadside equipment and vehicles to address applications to improve safety, mobility and environmental efficiency. In order to verify that the defined messages will satisfy these applications, a systems engineering process has been employed that traces use cases to requirements and requirements…

IEC 62402:2019 provides requirements and guidance for obsolescence management applicable to any organization that is dependent on another organization to obtain value from the usefulness of the items that it provides. A cost-effective obsolescence management process and the activities used to implement the process are applicable throughout all phases of an item’s life cycle. This document covers…

This document specifies requirements for 13 grades of cut steel wire abrasives, as supplied for blast-cleaning processes. It specifies ranges of particle sizes, together with corresponding grade designations. Values are specified for hardness, density, defect/structural requirements, metallographic structure and chemical composition. This document is suitable for cut steel wire supplied for blast…

This document provides a framework and consistent terminology for specifying user requirements. It specifies the common industry format (CIF) for a user requirement specification including the content elements and the format for stating those requirements. NOTE 1 A user requirements specification is the formal documentation of a set of user requirements, which aids in the development and…

This document specifies a method, carried out under standard conditions, for preparing and storing a sample of a multicomponent coating system and subsequently assessing its pot-life by measuring a particular property/ies. Reactive systems curing within a short period of time, e.g. 3 h, will have the end of their pot life so near to the gel point that they will need to be tested for that…

IEC 60704-3:2019 describes procedures for determining and verifying the declared values of the noise emitted by household and similar appliances. It applies to all categories of household and similar electrical appliances covered by IEC 60704-1 and all parts of IEC 60704-2, which include particular requirements for special categories of appliances. It applies to appliances being produced in…

IEC 62271-107:2019 applies to three-pole-operated fused circuit-switchers designed with rated voltages above 1 kV up to and including 52 kV for use on three-phase alternating current systems of either 50 Hz or 60 Hz. This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical…

IEC 60704-3:2019 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60704-3:2019 describes procedures for determining and verifying the declared values of the noise emitted by…
