Kranai. Varikliniai suktuvai ir keltuvai. 2 dalis. Varikliniai keltuvai

This document is applicable to the design, information for use, maintenance and testing of power driven hoists, compact or open construction, with or without trolleys for which the prime mover is an electric, hydraulic or pneumatic motor. They are designed for the lifting and lowering of loads that are suspended on hooks or other load lifting attachments. Hoists can be used either in cranes, in other machines, e.g. rail dependent storage and retrieval equipment, monorail conveyors or by itself. This document is applicable to the following types of hoists and applications: — rope hoists; — chain hoists; — belt hoists; — NGL building hoists; — winches used for lifting operation; — hoists designed for holding stationary loads above persons; — hoists designed for high risk applications. This document does not apply to belt hoists with steel belts as hoisting media. This document does not apply to builders’ hoists for transportation of goods having a guided platform or having a guided load carrying device. This document is not applicable to the following hazards: — this document does not cover hazards related to the lifting of persons. This document does not specify additional requirements for hazards related to the use of hoists in explosive atmospheres in underground mines. This document does not address the hazards related to autonomous operation and use of self-evolving behaviour of the power driven hoists. The significant hazards covered by this document are identified in Annex H. This document is not applicable to power driven hoists manufactured before the date of its publication.

Sprogiosios atmosferos. 20-1 dalis. Medžiagų charakteristikos dujoms ir garams klasifikuoti. Bandymo metodai ir duomenys (ISO/IEC DIS 80079-20-1:2026)

This document is published as a dual log standard and provides guidance on classification of gases and vapours. It describes a test method intended for the measurement of the maximum experimental safe gaps (MESG) for gas-air mixtures or vapour-air mixtures under normal conditions of temperature and pressure (20 °C, 101,3 kPa) so as to permit the selection of an appropriate group of equipment. This document also describes a test method intended for use in the determination of the auto-ignition temperature (AIT) of a vapour-air mixture or gas-air mixture at atmospheric pressure, so as to permit the selection of an appropriate temperature class of equipment. Values of chemical properties of materials are provided to assist in the selection of equipment to be used in hazardous areas. Further data may be added as the results of validated tests become available. The materials and the characteristics included in a table (see Annex B) have been selected with particular reference to the use of equipment in hazardous areas. The data in this document have been taken from a number of references which are given in the bibliography. These methods for determining the MESG or the AIT may also be used for gas-air-inert mixtures or vapour-air-inert mixtures. However, data on air-inert mixtures are not tabulated. Keywords: classification of gases and vapours, measurement of the maximum experimental safe gaps (MESG)

Bitumas ir bituminiai rišikliai. Papildomų specifikacijų, susijusių su eksploatacinėmis charakteristikomis, sistema

This document specifies a framework of additional characteristics and associated test methods for bitumens and bituminous binders, which is complementary to other product standards for bitumens and bituminous binders. This document is applicable to bitumens and bituminous binders suitable for use in paving applications, but it is also applicable for other uses such as waterproofing membranes. With regard to paving applications, the following characteristics are addressed: - resistance to permanent deformation (rutting); - resistance to low-temperature cracking; - resistance to ravelling; - resistance to fatigue cracking; - temperature susceptibility; - equi-stiffness temperature and phase angle; - durability (evolution of equi-stiffness temperature and phase angle); - mixing and handling characteristics (paving and compaction) temperatures; - additional characteristics (e.g. solubility, elastic recovery and storage stability). Not all the properties and characteristics established in the framework are universally relevant to all binders. For example, elastic recovery is not relevant for unmodified binders.
