IEC TS 62607-6-17:2023 establishes a standardized method to determine the key control characteristic order parameter for graphene-based material and layered carbon material by X-ray diffraction (XRD) and transmission electron microscopy. The order parameter is analysed from two perspectives: z-axis and x-y-axis. In the z-axis the order parameter is derived from the full width at half maximum (…

This document specifies: —     physical and chemical tests on raw rubbers; —     standard materials, standard test formulations, equipment, and processing methods for evaluating the vulcanization characteristics of emulsion- and solution-polymerized styrene-butadiene rubbers (SBRs), including oil-extended rubbers. It applies to those rubbers listed in Table 1 which are normally used in vulcanized…

This document specifies the requirements and test methods for sterilized absorbent points used in endodontic procedures. Absorbent points are marketed sterilized or non-sterilized. The requirements apply to absorbent points which have been sterilized once in a manner approved by the manufacturer. This document specifies numerical systems and a colour-coding system for designating the sizes of…

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 62899-202:2023 defines the terms and specifies the standard test methods for characterization and evaluation of…

IEC 61156-11:2023 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 61156-11:2023 describes cables intended to be used for single balanced pair (office, home, industrial)…

IEC 62899-202:2023 defines the terms and specifies the standard test methods for characterization and evaluation of conductive inks. This document also provides measurement methods for evaluating the properties of conductive layers made both from an additive process using conductive inks and from a subtractive process used in printed electronics. This edition includes the following significant…

1 Scope This document provides guidance for the application of the requirements contained in ISO 11607-1 and ISO 11607-2. It does not add to, or otherwise change, the requirements of ISO 11607-1 and ISO 11607-2. This is an informative document, not normative. It does not include requirements to be used as basis of regulatory inspection or certification assessment activities. The guidance can be…

1 Scope 1.1 Introduction This Standard describes the test procedures, test set-ups, and calculations required to determine the performance, capacities, energy consumption, and overall efficiency of gas-fired and oil-fired combined radiant space and water heating systems (combos) with hydronic heat distribution. 1.2 Type of standard This Standard establishes laboratory methods for testing and…

1 Scope 1.1 General This Standard applies to free-standing, selective-type storage racks where the principal structural components are upright frames and load support beams. These storage racks include selective racks, double-deep racks, very narrow aisle (VNA) racks, push-back racks, pallet-flow racks, pallet shuttle racks, and automated storage and retrieval system (AS/RS) racks. Note:…

1 Scope 1.1 General 1.1.1 Application This Standard applies to hyperbaric chambers that have as their primary function the subjection of humans to pressure environments exceeding 1 atmosphere absolute, such as those required in a) diving operations; b) work under compressed-air conditions; c) medical treatment; d) training; and e) research. 1.1.2 Minimum requirements This Standard…
