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…

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)…

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…

The ISO 19124 series is focused on calibration and validation (Cal/Val) of remote sensing data, which are collected by a sensor on-board a platform in a mission, and products derived in part or whole from the data. The ISO 19124 series defines the metadata related to the calibration and validation process that has not been defined in other ISO/TC 211 International Standards. The metadata allows…

Scope 1.1 This Standard applies to visual signaling devices intended for indoor and/or outdoor installation: a) In Canada only: in accordance with CSA C22.1, Canadian Electrical Code, Part I, Safety Standard for Electrical Installations; and with ULC-S524, Standard for Installation of Fire Alarm Systems. b) In the United States only: in accordance with the National Electrical Code, NFPA 70,…

This document specifies a methodology and provides related requirements, recommendations and guidance for the design and integration of safety‐related parts of control systems (SRP/CS) that perform safety functions, including the design of software. This document applies to SRP/CS for high demand and continuous modes of operation including their subsystems, regardless of the type of technology…

This document specifies test methods for flexible non-thrust resistant socket-and-spigot joints with elastomeric sealing elements for buried and aboveground glass-reinforced thermosetting plastics (GRP) pipeline applications. It covers methods of test for the leaktightness and resistance to damage of the joint only, when subject to specified combinations of longitudinal extension (draw), angular…
