NFC forumo specifikacijos. 2 dalis. NFC duomenų mainų formatas

The NFC Data Exchange Format (NDEF) specification defines a message encapsulation format to exchange information between two NFC Forum Devices. NDEF is a lightweight, binary message format that can be used to encapsulate one or more application-defined payloads of arbitrary type and size into a single message construct. Each payload is described by a type, a length, and an optional identifier. Type identifiers can be URIs, MIME media types, or NFC-specific types. This latter format permits compact identification of well known types commonly used in NFC Forum applications, or self-allocation of a name space for organizations that wish to use it for their own NFC-specific purposes. The NDEF Payload Length is an unsigned integer that indicates the number of octets in the payload. A compact, NDEF short-record layout is provided for very small payloads. The optional NDEF Payload Identifier enables association of multiple payloads and crossreferencing between them. NDEF Payloads can include nested NDEF Messages or chains of linked chunks of length unknown at the time the data is generated. NDEF is strictly a message format, which provides no concept of a connection or of a logical circuit, nor does it address head-of-line problems.

Naftos ir dujų pramonė, įskaitant mažesnio anglies dioksido pėdsako energijos gamybą. Transportavimo vamzdynais sistemos. Patikimumu pagrįstų ribinių būsenų metodai (ISO/DIS 16708:2026)

ISO 16708:2006 specifies the functional requirements and principles for design, operation and re-qualification of pipelines in the petroleum and natural gas industries using reliability based limit state methods as permitted by ISO 13623. Reliability-based limit state methods provide a systematic way to predict pipeline safety in design and operation. ISO 16708:2006 supplements ISO 13623 and can be used in cases where ISO 13623 does not provide specific guidance and where limit states methods can be applied, such as, but not limited to - qualification of new concepts, e.g. when new technology is applied or for design scenarios where industry experience is limited, - re-qualification of the pipeline due to a changed design basis, such as service-life extension, which can include reduced uncertainties due to improved integrity monitoring and operational experience, - collapse under external pressure in deep water, - extreme loads, such as seismic loads (e.g. at a fault crossing), ice loads (e.g. by impact from ice keels), - situations where strain-based criteria can be appropriate. ISO 16708:2006 applies to rigid metallic pipelines on-land and offshore used in the petroleum and natural gas industries.

Elektros tiekimo saugos įrangai centrinės sistemos

This document specifies the general requirements for central power supply systems for an independent energy supply to essential safety equipment. This standard covers systems that are permanently connected to AC supply voltages not exceeding 1 000 V and use batteries as an alternative power source. Central safety power supply systems are intended to ensure energy supply to emergency escape lighting in the event of normal supply failure and may be suitable for energizing other essential safety equipment, for example: – electric circuits of automatic fire extinguishing installations; – paging systems and signalling safety installations; – smoke extraction equipment; – carbon monoxide warning systems; – special safety installations related to specific buildings, e.g. high-risk areas. The power supply of CPS systems should be dedicated only to the essential safety equipment, and not for other type of loads such as general purpose IT or industrial systems etc. Combinations of the aforementioned safety equipment types are permitted together on the same central safety power supply system providing the availability for safety equipment loads is not impaired. A fault occurring in a circuit should not cause the interruption in any other circuit used to supply essential safety equipment. Schematic representations of typical central safety power supply equipment are depicted in Clause 4. Power supply systems for fire alarm equipment that are covered by EN 54 (series) are excluded.

Trąšos, kalkinimo medžiagos ir inhibitoriai. Chloridų kiekio nustatymas

This document specifies references to methods for the determination of the chloride content in organic fertilizers, organo-mineral fertilizers, inorganic fertilizers, liming materials and inhibitors. This document is applicable to fertilizing product blends where the blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed only of inorganic products, the European Standard for inorganic fertilizers applies. NOTE Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.

Eurokodas 1. Poveikiai konstrukcijoms. 4 dalis. Silosai ir rezervuarai

1.1 Scope of EN 1991-4 (1) This document provides rules for calculating actions for the structural design of silos and tanks. NOTE 1 Silos are used for the storage of particulate solids. Tanks are used for the storage of liquids. NOTE 2 For limitations on rules for silos given in this document, see 1.3. NOTE 3 For limitations on rules for tanks given in this document, see 1.4. (2) This document includes some provisions for actions on silo and tank structures that are not only associated with the stored particulate solids or liquids (e.g. the effects of thermal differentials) but substantially affected by them. NOTE Liquid loads on tanks are very precisely defined. Many loads on silos are not known with great precision. This document provides guidance for many practical situations for which very limited certain knowledge is available, and the information is derived from the limited experimental and analytical information available, coupled with conclusions drawn from failure investigations. The information is not based on a sound statistical treatment of experimental data. (3) This document is intended for use with concrete, steel, aluminium, timber and FRP storage structures. NOTE FRP is the standard acronym for fibre reinforced polymer materials. (4) This document is also applicable for the structural assessment of existing silos and tanks, unless otherwise specified by the relevant authority or, if not specified, agreed between the relevant parties for the specific project. NOTE 1 Changes in filling or discharge arrangements, changes in the wall friction of inner surfaces, or in the use of the silo, including storage of different particulate solids, can be reasons for assessing existing silos. NOTE 2 Differentiation of the liquid stored can be a reason for assessing existing tanks. 1.2 Assumptions (1) The assumptions of EN 1990-1 apply. (2) This document is intended to be used in conjunction with EN 1990 1, with the other parts of EN 1991, EN 1992, EN 1993, EN 1995, EN 1997, EN 1998 and EN 1999 where relevant to the design of silos and tanks. 1.3 Limitations on silos 1.3.1 Geometrical limitations (1) The following geometrical limitations apply to the design rules for silos and silo batteries (see 3.2.59 and 3.2.60) covered by this document: - the silo planform cross-section shapes are limited to those shown in Figure 1.1c. NOTE 1 Further information concerning planform cross-section geometries is given in Clause 7. NOTE 2 For the determination of the effective diameter dc of the silo see Figure 1.1c; - the following dimensional limitations on the aspect ratio for free-standing single cell silos hc/dc, the overall height hb and the effective diameter dc apply (see Figure 1.1): hc/dc < 10 (1.1) hb < 100 m (1.2) dc < 60 m (1.3) NOTE 3 See Figure 1.1 for hc, dc and hb. - the structural transition lies in a single horizontal plane (see Figure 1.1a). [Figure 1.1 - Silo forms showing dimensions and pressure notation] (2) Only hoppers that are conical (i.e. axisymmetric), rectangular pyramidal with a/b ≤ 1,5, wedge-shaped (i.e. with two vertical end walls on opposite sides) or oblique are covered by this document. Other hopper shapes and hoppers with internal structures require special considerations. (3) Silos with an oblique conical hopper used to achieve an eccentric outlet are covered by this document. (4) Silos with an oblique hopper are covered, but generally silos with a systematically non-symmetric geometry are not specifically covered by this document. These situations include a chisel hopper (i.e. a wedge hopper beneath a circular cylinder) and hoppers with an elongated outlet other than wedge shaped. 1.3.2 Limitations on the stored particulate solids (1) The following limitations on the stored particulate solids apply to the design rules for silos contained in this document: ...

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.
