This document specifies a procedure for the evaluation of centreline segregation of continuously cast slabs, including sampling, sample preparation and evaluation method. This document is applicable for low carbon steel slabs for pipe production manufactured by continuous casting. These steels have a typical chemical composition as follows (mass percentages): — C ≤ 0,12 % — Mn ≤ 2,0 % — Si ≤ 0,5 % — Ti + Nb + V ≤ 0,2 % The common dimensions of these slabs are in the following ranges: — Slab width: 800 mm to 2 600 mm — Slab thickness: 150 mm to 450 mm The evaluation methods covered by this document are based on macroscopic etching of slab samples followed by visual inspection by means of human eye or camera systems. The procedures for sampling described in 5.1 to 5.3 of this document are applicable to steels slabs in general (e. g. other steel grades or dimensions). However, the etching procedure (see 5.4) in combination with the evaluation methods described in Clause 6 have been developed especially for the application on pipeline steels as given above. Thus, they are not applicable to other steel grades, product types or dimensions without a prior validation. Any extension or modification beyond the scope of this document necessitates a separate agreement between producer and customer.

1.1 This European Standard establishes general principles for the execution of bored piles (see 3.2). NOTE 1 This standard covers piles or barrettes which are formed in the ground by excavation and are structural members used to transfer actions and/or limit deformations. NOTE 2 This standard covers piles with circular cross-section (see Figures 1 and A.1a)) and barrettes (see 3.3) with rectangular, T or L or any other similar cross-section (see Figure 2) concreted in a single operation. NOTE 3 In the standard the term pile is used for circular cross-section structure and the term barrette for other shapes. Both are bored piles. 1.2 This European Standard applies to bored piles (see Figure 3) with: - uniform cross-section (straight shaft); - telescopically changing shaft dimensions; - excavated base enlargements; or - excavated shaft enlargements. NOTE The shape of a pile base and of an enlargement depends on the tool used for the excavation. 1.3 This European Standard applies (see Note) to: - bored piles with a depth to width ratio  5; - piles (see Figures 1 and 3) with a shaft diameter 0,3 m  D  3,0 m; - barrettes (see Figure 2) with the least dimension Wi  0,4 m, a ratio LBiB / Wi between its largest and its least dimensions  6 and a cross-sectional area A  15 m²; - piles with circular precast elements used as structural member (see Figure 7) with a least dimension DP  0,3 m; - barrettes with rectangular precast elements used as structural member with a least dimension WP  0,3 m. NOTE The standard covers a large range of diameters. For small diameter bored piles less than 450 mm, the general specification can be adapted to cater for the lack of space (e.g. minimum bars number and spacing). 1.4 This European Standard applies to piles with the following rake (see Figure 4): - n  4 (  76°); - n  3 (  72°) for permanently cased piles.

This document specifies requirements and provides a framework for the digital transformation of Facility Management (FM). It defines the principles, processes and supporting elements for organizations to apply when planning, implementing and improving digitalization within FM. The purpose of this standard is to ensure that FM organizations can adopt digital practices in a consistent and effective manner that improves operational efficiency, enhances decision-making and strengthens resilience. The standard is written as a companion to EN ISO 41001 [5] Facility management — Management systems — Requirements with guidance for use and EN 15221-8 [2] Facility management — Principles and processes. Its role is not to duplicate the management system requirements of EN ISO 41001 [5] or the principles and processes of EN 15221-8 [2], but to provide the digitalization dimension that complements both. NOTE Annex B describes the relationship between this document and other standards. This standard applies broadly. It is relevant to: — organizations of any type, size, or sector engaged in FM; — both in-house FM functions and outsourced FM service providers; — all phases of FM service delivery and the asset life cycle. Certain elements are outside the scope of this document. General FM principles and processes are covered in EN 15221-8 [2], while the management system requirements for FM are addressed by EN ISO 41001 [5]. These exclusions ensure that this document remains focused on digital transformation as a distinct, yet integrated, component of FM.

Dažai ir lakai. Dirbtinio klimato poveikis, įskaitant dengimą rūgštimi (ISO/DIS 15110:2026)

ISO 15110:2017 specifies a so-called acid dew and fog test (ADF test) as an accelerated laboratory test method for simulating, by the use of artificial acidic precipitation, the damaging effects of acidic atmospheric precipitation in association with UV radiation, neutral condensed precipitation, and changing temperature and humidity. This test method is intended to be used in evaluating, on the basis of relative performance rankings, the suitability of painted materials for use in outdoor environments with acidic precipitation. It is not intended to generate the same extent of damage or the same damage pattern as in outdoor weathering, but rather to give a ranking which is similar to that which would be obtained in outdoor weathering. The method produces damage which is more homogeneous, allows fewer specimens to be exposed (and hence more rapid testing) and enables evaluation of the exposed specimens to be carried out using methods which are more objective than visual assessment.

This European Standard covers only the types of sprinkler specified in EN 12259 1 (see Annex L). The requirements and recommendations of this European Standard are also applicable to any addition, extension, repair or other modification to a sprinkler system. They are not applicable to water spray or deluge systems. It covers the classification of hazards, provision of water supplies, components to be used, installation and testing of the system, maintenance, and the extension of existing systems, and identifies construction details of buildings which are the minimum necessary for satisfactory performance of sprinkler systems complying with this European Standard. This European Standard does not cover water supplies to systems other than sprinklers. Its requirements can be used as guidance for other fixed firefighting extinguishing systems, provided that any specific requirements for other firefighting extinguishing supplies are taken into account. This European Standard is intended for use by those concerned with purchasing, designing, installing, testing, inspecting, approving, operating and maintaining automatic sprinkler systems, in order that such equipment will function as intended throughout its life. This European Standard is intended only for fixed fire sprinkler systems in buildings and other premises on land. Although the general principles might well apply to other uses (e.g. maritime use). For these other uses additional considerations should be taken into account. The requirements are not valid for automatic sprinkler systems on ships, in aircraft, on vehicles and mobile fire appliances or for below ground systems in the mining industry. Sprinkler system design deviations might be allowed when such deviations have been shown to provide a level of protection at least equivalent to this European Standard, for example by means of full-scale fire testing where appropriate, and where the design criteria have been fully documented.
