The proposed standard document specifies requirements for ensuring quality, safety and performance of laboratory-developed tests (LDT). It outlines the general principles and assessment criteria by which LDT shall be designed, developed, manufactured, validated and monitored for internal use by medical laboratories. While the proposed standard follows a current best practice and state-of-the art approach, it does not provide specific details on how to achieve these requirements within certain disciplines of medical laboratory testing. This document does not cover requirements for examination procedures developed by research or academic laboratories developing and using testing systems for non-in-vitro-diagnostic purposes. However, the concepts presented in this document may also be useful for these institutions. The proposed standard does not apply to the design, development and industrial production of commercially used in vitro diagnostic medical devices.

This document specifies a horizontal in vitro method for the molecular identification and differentiation of the monophasic variant of Salmonella enterica subsp. enterica serovar Typhimurium (1,4[5],12:i:- ) lacking, or not expressing, the second H phase H:1,2, starting from isolates. The method detects specific DNA sequences of an intergenic region of the first H phase flagellin cluster for identification of Salmonella enterica subsp. enterica serovar Typhimurium (further called Salmonella Typhimurium) and specific DNA sequences of genes associated with second H phase flagellar antigen expression.

The method is applicable for:

— differentiation of the isolate under analysis between monophasic Salmonella Typhimurium and the monophasic variant of another Salmonella non-Typhimurium serovar that has the same antigenic formula;

— identification of the isolate under analysis being either monophasic Salmonella Typhimurium or (biphasic) Salmonella Typhimurium.

This document is applicable for the analysis of a pure culture belonging to the genus Salmonella, isolated from:

— products intended for human consumption;

— products intended for animal feeding;

— environmental samples in the area of food and feed production and handling;

— samples from the primary production stage.

This document can also be applied in other domains for identification of monophasic Salmonella Typhimurium (e.g. environmental, human health, animal health).

The global description "wall saw and wire saw equipment" contains two differing types of machines for use in the construction industry, and both used to make cuts on walls, ceilings and floors composed of mineral construction materials and/or composite materials. The many different cutting tasks and choice of operating method determine the type of machine to be used for each application. The machines may therefore be split into the following two principal classifications: - Wall saws - exclusively rail guided - transportable. - Wire saws - transportable. The machines are intended for the use of diamond tools. The types of cutting tools used in conjunction with the machines as described above fall within the design and use parameters supplied by the manufacturer. Cutting debris generated by the cutting action is removed from the cutting joint by a medium such as water directed to the cutting tool. Machines covered by this standard may be powered by: electric motor, IC engine, electro-hydraulic drive and IC engine-hydraulic drive. This European Standard deals with all significant hazards, hazardous situations and events relevant to wall saws and wire saws machinery, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards generated by the cutting process work cycle. For special applications, for example, when working in potentially explosive atmospheres, additional safety requirements is necessary which are not covered by this standard. This European Standard does not apply for wire saws intended for quarrying and stationary machining of natural stone as covered by prEN 15163. This European Standard applies primarily to machines which are manufactured after the date of approval by CEN of this standard.

This document specifies the requirements for the ultrasonic testing of steel castings (with ferritic structure) for highly stressed components and the methods for determining internal discontinuities by the pulse-echo technique. Purchasers determine if components are highly stressed based on the need for performance or safety. This document applies to the ultrasonic testing of steel castings which have usually received a grain-refining heat treatment and which have wall thicknesses up to and including 600 mm. For greater wall thicknesses, special agreements apply with respect to test procedure and recording levels. This document does not apply to austenitic steels and joint welds.

ISO 14404-1:2013 specifies calculation methods for the carbon dioxide (CO2) intensity of plant where steel is produced through a blast furnace. It includes boundary definition, material and energy flow definition and emission factor of CO2. Besides direct source import to the boundary, upstream and credit concept is applied to exhibit the plant CO2 intensity. ISO 14404-1:2013 supports the steel producer to establish CO2 emissions attributable to a site. ISO 14404-1:2013 cannot be used to calculate benchmarks or to compare CO2 intensities of production processes that are operated inside the site.
