This document gives guidelines for the design and use of environmental performance evaluation (EPE) within an organization. It is applicable to all organizations, regardless of type, size, location and complexity. This document does not establish environmental performance levels. It is not intended for use for the establishment of any other environmental management system (EMS) conformity…

This document specifies the conditions and methods used for testing and characterizing the water distribution patterns of irrigation sprinklers. The term sprinkler is used in this document in a broad generic sense and is meant to cover a wide variety of products. The specific performance measurements addressed include distribution uniformity, wetted radius, and water jet trajectory height. This…

IEC 60335-2-34:2021 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 60335-2-34:2021 deals with the safety of sealed (hermetic and semi-hermetic type) motor-compressors, their…

IEC 60335-2-34:2021 deals with the safety of sealed (hermetic and semi-hermetic type) motor-compressors, their protection and control systems, if any, which are intended for use in equipment for household and similar purposes and which conform with the standards applicable to such equipment. It applies to motor-compressors tested separately, under the most severe conditions that may be expected…

This document specifies the minimum essential variables in order to produce a component of the required consistency and quality for the following thermal joining processes: — ultrasonic welding/staking/spot welding; — infrared welding; — hot gas convection welding; — linear vibration welding; — orbital vibration welding; — spin welding; — laser welding; — hot plate…

This document specifies a method for the determination of moisture in a general analysis sample by drying the sample in an oven. This method is suitable for use for general analysis samples in accordance with CEN/TS 15414‑1[3][1]. It is applicable to all solid recovered fuels. If solid recovered fuels contain large amounts of oil-fractions the Karl-Fischer-Method (for example ISO 760) is…

IEC 61800-2:2021 applies to adjustable speed electric AC power drive systems, which include semiconductor power conversion and the means for their control, protection, monitoring, measurement and the AC motors. It applies to adjustable speed electric power drive systems intended to feed AC motors from a BDM or CDM connected to line-to-line voltages up to and including 35 kV AC 50 Hz or 60 Hz and…
