IEC 61400-6:2020 specifies requirements and general principles to be used in assessing the structural integrity of onshore wind turbine support structures (including foundations). The scope includes the geotechnical assessment of the soil for generic or site specific purposes. The strength of any flange and connection system connected to the rotor nacelle assembly (including connection to the yaw…

Scope The requirements of this certification document concern the materials and concrete properties; fabrication (including placing, finishing, and curing); as well as the methods related to the handling, transportation, and installation of, and repairs to the precast concrete elements. The quality management system elements that shall be implemented within the manufacturer’s operations are also…

1.1 This Standard specifies the requirements for the on-site manufacture and installation of light density, open cell spray applied semi-rigid polyurethane foam to produce a material that meets the physical property requirements of CAN/ULC-S712.1, Standard for Thermal Insulation – Light Density, Open Cell Spray Applied Semi-Rigid Polyurethane Foam – Material Specification. The material only…

This document defines the minimum design, installation, commissioning, operation, inspection and maintenance requirements, for the safety, and, where appropriate, for the performance of public and non-public fuelling stations that dispense gaseous hydrogen to light duty road vehicles (e.g. fuel cell electric vehicles). This document is not applicable to the dispensing of cryogenic hydrogen, or…

1 Scope This document provides requirements and recommendations for human-centred design principles and activities throughout the life cycle of computer-based interactive systems. It is intended to be used by those managing design processes, and is concerned with ways in which both hardware and software components of interactive systems can enhance human–system interaction. NOTE Computer-based…

1 Scope 1.1 This Standard sets forth characteristics of effective and durable installation methods, in both new and existing buildings, of fenestration products within the scope of AAMA/WDMA/CSA 101/I.S.2/A440 that are intended for installation in buildings of all occupancies to which NBC Parts 3, 4, 5, and 6 of Division B apply. 1.2 In addition to fenestration products within the scope of…

1 Scope 1.1 This Standard specifies the design, installation, operation, and maintenance of site-built and modular gaseous hydrogen fuelling stations (HFS) intended to fuel on-road vehicles. 1.2 Unless otherwise stated, the standard conditions are as follows: temperature 15 °C and pressure 101 kPa. 1.3 In case of conflict between this Standard and federal, provincial, state, or local…

This document provides information on how to assess the severity of machine tool spindle vibrations measured on the spindle housing. It gives specific guidance for assessing the severity of vibration measured on the spindle housing at customer sites or at the machine tool manufacturer's test facilities. Its vibration criteria apply to gear-driven spindles intended for stationary machine…

CISPR 16-1-3:2004+A1:2016+A2:2020 is designated a basic standard, which specifies the characteristics and calibration of the absorbing clamp for the measurement of radio disturbance power in the frequency range 30 MHz to 1 GHz. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. In this edition a more detailed calibration method for…

This document specifies essential requirements and related test methods for non-electrically driven portable infusion devices, thereafter called "device". It is applicable to devices designed for continuous (fixed or adjustable) flow and/or for bolus neuraxial and intravascular or hypodermic applications. NOTE Sites for the neuraxial application include the spine, intrathecal or…
