Šaldymo sistemos ir šilumos siurbliai. Saugos ir aplinkosauginiai reikalavimai. 1 dalis. Pagrindiniai reikalavimai, apibrėžtys, klasifikavimas ir atrankos kriterijai

This document specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment and establishes procedures for the operation, maintenance and repair of refrigerating systems and the recovery of refrigerants. The term “refrigerating system” used in this document includes heat pumps. This part of EN 378 specifies the classification and selection criteria applicable to refrigerating systems. These classification and selection criteria are used in Parts 2, 3 and 5. This document applies to: a) refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard e.g. [7] b) secondary cooling or heating systems; c) the location of the refrigerating systems; d) replaced parts and added components after adoption of this document if they are not identical in function and in the capacity. Systems using refrigerants other than those listed in Part 5 of this standard are not covered by this document. Clause 7 specifies how to determine the refrigerant quantity safety limit in a given space, which, when exceeded, requires additional protective measures to reduce the risk. This document is not applicable to refrigerating systems which were manufactured before the date of its publication as a European Standard except for extensions and modifications to the system which were implemented after publication. This document is applicable to new refrigerating systems, extensions or modifications of already existing systems, and for existing stationary systems, being transferred to and operated on another site. This document also applies in the case of the conversion of a system to another refrigerant type, in which case conformity to the relevant clauses of Parts 1, 2, 3 and 5 of the standard is expected to be assessed. Product family standards dealing with the safety of refrigerating systems take precedence over horizontal and generic standards covering the same subject.

Termoplastikinių pusgaminių suvirintųjų jungčių bandymai. 6 dalis. Tempimo žemoje temperatūroje bandymas

This document specifies the dimensions, the method of sampling and the preparation of the test specimens, also the conditions for performing the low temperature tensile test perpendicular to the weld in order to determine the low temperature tensile welding factor. A low temperature tensile test can be used in conjunction with other tests (e.g. bend, tensile creep, macro) to assess the performance of welded assemblies, made from thermoplastics materials. The low temperature tensile welding factor and the appearance of the fracture surface provide a guide regarding the ductility of the joint and the quality of the work. The test is applicable to co-axial or co-planar welded assemblies made from thermoplastics materials filled or unfilled, but not reinforced, irrespective of the welding process used. The test is not applicable for co-axial welded assemblies of an external diameter less than 20 mm.

This document specifies general principles for the execution, supervision, inspection, testing and monitoring of in situ soil mixing works (Deep Mixing) carried out by two different methods: dry mixing and wet mixing. Soil mixing considered in this document is limited to methods which involve: - mixing by rotating mechanical mixing tools, including jetting and/or compressed air assistance, where the lateral support provided by the surrounding ground is not removed; - different shapes and configurations of soil mixing elements, either columns, panels, walls or any combination of more than one single element, with or without overlapping; - treatment of soils and fills, including brownfields, sludges, etc., with possible limited penetration into the rock; - mass mixing; - environmental mixing, involving installation of containment and permeable reactive barriers and solidification/stabilization of contaminated soils and sludges. This standard does not apply to shallow soil stabilization, which consists of granulating the surface soil and mixing it with binder using soil stabilizing machines to improve soil performance as an alternative to soil replacement, typically in road works.

Adityvioji gamyba. Duomenys. AG dalių duomenų paketai (ISO/ASTM DIS 52951:2025)

This document provides the methods, parameter sets and models to develop and utilize a data package for a part created using AM technologies (AM part). This document is scoped to the information requirements associated with workflow of the fabrication of an AM part, from design to acceptance. Peripheral information related to entities such as organization, facility, operator, security, and others is addressed for sake of completeness; but is not the focus of this document and can be defined elsewhere. This document provides the means to develop an organizational or application-specific data package for the communication between and amongst the designer, the manufacturer, and all acceptance authorities, among other potential stakeholders. This document does not impose a plan of execution to produce an AM part, though a digital thread is provided to establish a referenceable information workflow. The requirements set forth in this document are based on the fabrication of a part using the PBF-LB/M process. While specific details directly relate to PBF-LB/M, generalized workflow requirements can be related to any AM process.
