Abstract: Within the context of the ISO/IEEE 11073 family of standards for device communication, this standard establishes a normative definition of the communication between personal strength fitness devices and managers (e.g., cell phones, personal computers, personal health appliances, and set top boxes) in a manner that enables plug-and-play interoperability. It leverages appropriate portions of existing standards including ISO/IEEE 11073 terminology and information models. It specifies the use of specific term codes, formats, and behaviors in telehealth environments restricting optionality in base frameworks in favor of interoperability. This standard defines a common core of communication functionality for personal telehealth strength fitness devices. In this context, strength fitness devices are being used broadly to cover strength fitness devices that measure musculo-skeletal strength-conditioning activities. Keywords: medical device communication, personal health devices, strength fitness equipment

Kranai. Krovimo kranai

This document specifies requirements for design, calculation, examinations and tests of hydraulic powered loader cranes and their mountings on vehicles or static foundations. This document applies to loader cranes designed to be installed on: - road vehicles, including trailers, with load carrying capability; - tractors (road or agricultural), where only a towed trailer has capability to carry goods; - demountable bodies to be carried by any of the above; - other types of carriers (e.g. separate loaders, crawlers, rail vehicles, non-seagoing vessels); - static foundations. NOTE 1 A demountable body is a detachable frame designed to be carried by a vehicle or trailer. NOTE 2 A separate loader is a vehicle, with no load carrying capacity, equipped with a loader crane and designed to load or unload other vehicles and trailers. This document also applies to loader cranes equipped with special tools or interchangeable equipment (e.g. grapple, clamshell bucket, pallet clamp, etc.), as specified in the operator’s manual. This document does not apply to loader cranes used on board sea going vessels or to articulated boom system cranes which are designed as total integral parts of special equipment such as forwarders. The hazards covered by this document are identified in Clause 4. This document does not cover hazards related to the lifting of persons. NOTE 3 The use of cranes for lifting of persons can be subject to specific national regulations. This document is not applicable to loader cranes manufactured before the publication of this document. For loader cranes designed before the publication of this document, the provisions concerning stress calculations in the version of EN 12999 that was valid at the time of their design, are still applicable.

Potencialiai sprogiose atmosferose naudojamų ventiliatorių projektavimas

1.1 This document specifies the constructional requirements for fans constructed to Group II G (of explosion groups IIA, IIB and hydrogen) categories 1, 2 and 3, and Group II D categories 2 and 3, intended for use in explosive atmospheres. NOTE 1 Operation conditions for the different categories of fans used in this document are defined in Clause 4. 1.3 This document specifies requirements for design, construction, testing and marking of complete fan units intended for use in potentially explosive atmospheres in air containing gas, vapour, mist and/or dusts. Such atmospheres can exist inside (the conveyed atmosphere (flammable or not)), outside, or inside and outside of the fan. This document covers mechanical equipment, in particular fans. The “type of protection” as specified in EN ISO 80079 37:2016 is constructional safety. 1.4 This document is applicable to fans working in ambient atmospheres and with normal atmospheric conditions at the inlet, having — absolute pressures ranging from 0,8 bar to 1,1 bar, — and temperatures ranging from −20 °C to +60 °C, — and maximum volume fraction of 21 % oxygen content, — and an aerodynamic energy increase of less than 25 kJ/kg. NOTE 1 25 kJ/kg is equivalent to 30 kPa at inlet density of 1,2 kg/m3. This document can also be helpful for the design, construction, testing and marking of fans intended for use in atmospheres outside the validity range stated above or in cases where other material pairings need to be used. In this case, the ignition risk assessment, ignition protection provided, additional testing (if necessary), manufacturer's marking, technical documentation and instructions to the user, clearly demonstrate and indicate the equipment's suitability for the conditions the fan can encounter. NOTE 2 Temperatures below −20 °C can be considered. Material suitability can require specific evaluation for these temperatures. With lower temperature the explosion pressure increases, which leads to increased test pressures (see A.3) and can require specific testing. Although the standard atmospheric conditions in EN ISO 80079 36:2016 give a temperature range for the atmosphere of −20 °C to +60 °C the normal ambient temperature range for the equipment is −20 °C to +40 °C unless otherwise specified and marked. 1.5 This document does not apply to: — group I fans (fans for mining); — explosion group IIC (other than hydrogen); — category 1D fans; — cooling fans or impellers on rotating electrical machines; — cooling fans or impellers on internal combustion engines, vehicles or electric motors. NOTE 3 Measures for category 1D fans are given in EN 1127 1:2019. NOTE 4 Measures for explosion group IIC (other than hydrogen) are given in EN 1127 1:2019. NOTE 5 Measures for explosion group I are given in EN ISO/IEC 80079 38:2016 and EN 1127 2:2014.

Cemento bandymo metodai. 16 dalis. Atsparumas sulfatams. Kvadratinės prizmės metodas

This document describes a test method applicable to cast test specimens for evaluating the Sulfate Resistance (SR characteristic) of cements. Sulfate resistance means that these binders can be used in concrete bodies submitted to sulfate attacks. In these methods, the test is carried out under controlled exposure conditions using a defined concentration of sulfate solution. The chosen test conditions are intended to accelerate external sulfate attack. This test method is appropriate in particular for CEM III/A cements and other various binders, in particular those with pozzolanic main constituents. It is adapted from the CUR - NL - Civieltechnisch Centrum Uitvoering Research en Regelgeving (Centre for Civil Engineering Research and Codes) - Recommendation 48 - Suitability test for new cements for application in concrete. This test method is listed in European Assessment Document - EAD 150004-00-0301, Annex B.
