The American National Standard officially provides all applicable requirements to the dry seal pipe threads. Subject threads are based on the American pipe thread but they significantly differ from USA pipe thread because they are commonly designed to seal the pressure tight joints without having top use additional sealing components. In order to accomplish this purpose, some modification shall be made to the form of the thread and greater manufacturing accuracy shall be reached.

The roots of the internal and external threads truncate more than crests so their flats are slightly wider than crests. This results in the metal to metal contact occurring at the roots and crests either at the time of flank contact or prior to that... This document addresses different types of threads, notations and designations, applications, assembly limitations, tolerances and forms, basic dimensions of the threads and many other information and data.

Three appendices deal with the symbols and formulas, suggested tap drill sizes, specific pipe threads such as special and special-extra short and others. Data tables at the end of the standard provide additional information on basic dimensions, recommended assembly limitations etc.

This is the official release of the BS ISO 19018-04 standard. The publication is divided into several chapters. The first one defines the scope of the document, the following ones address related normative references and special units applicable to the maritime navigation; the others are as below - Course, heading, track and speed; Bearings; Corrections; Influence of currents and winds; Geographical coordinates, positions, lines, graphical symbols; Waypoint navigation; Terms of time; Astronomical navigation; Depth of water and tides; Terrestrial magnetism; Radar navigation; LORAN-C; Global Positioning System.

This team of authors and editors who prepared on this standard, made their best trying to include the maximum possible number of important and relevant abbreviations, maritime terms and graphical systems - they are all frequently used in marine navigation on board vessels. It shall be noted, however, that the abbreviations listed in this paper should not actually be used in math formulae; the symbols that are allowed to be used in formulae are mentioned. The navigation itself if the process of finding the exact position of the ship; it also includes the planning, recording and controlling of how the vessel is moving from one position to another.

This technical code was prepared to address the conditions pertaining to the UK and; note that local conditions may also necessitate some modifications. The reference is actually made to BS not ES due to the most relevant European Standards being in the pre-standard form. The user shall apply some engineering judgement to properly determine if the recommendations of this code shall be followed and, if so, when they shall not.

The present code is intended for use by the industry engineers having some basic knowledge of the subject. This standard consists of the several parts, first one is the code of practice for general criteria, followed by design of quay walls, jetties and dolphins - design of drydocks, locks, shipways, shipbuilding berths, shiplifts, dock and lock gates - code of practice design of fendering, mooring systems, dredging and land reclamation - design of inshore moorings, floating structures, and breakwaters. Note that the offshore structures are not covered by this Code.

Same applied to the structures in inland waters. Additionally, note that this Code does not provide any guidance on the financial criteria though it is understood that proper economic evaluation shall be made for each project associated with the engineering criteria addressed by this Code.

The classic British Standard related to one of the most reliable and popular methods of nondestructive evaluation. The chapters making this document introduce the reader to the magnetic particle flaw detection, define the scope and provide the references and basic definitions, address the equipment used during the inspection, detecting media, all associated procedures (preparation, magnetization, current flow/threading bar or cable/rigid coil techniques, flexible cable technique, magnetic flow, induced current flow techniques, viewing and recording of indications, proper reporting, demagnetization and, finally, cleaning.

The Appendixes at the end of the publication provide some necessary supplementary data. In fact, the application of this method of nondestructive evaluation has already been described within several BS standards over the past years and it was considered necessary to prepare a separate basic standard that would address this particular method. And this is how the present BS 6072 standard has been developed and subsequently released - it provides people with a very detailed info on this method; however, we have to mention that some slight variation in the regular technique might be required for a number of particular applications.

The WPS referred to in the present British Standard, are required in order to provide a well defined basis for planning of any construction operations that would include welding, as well as for quality control during welding, evaluation of the established weld seams, assessment of the welding connections etc.

Welding itself is considered a very special process in the terminology of quality system standards - such standards would usually imply that special processes are to be carried out in full accordance with the written WPS, i.e. welding procedure specifications. Any possible deviations, as well as distortions and other imperfections, can be evaluated by means of the various nondestructive testing (NDT) methods on the newly established weld seam.

The special problem is constituted by the metallurgical deviations, because today's level of NDT technology does not allow for the nondestructive evaluation of the mechanical properties - this necessitated the establishment of a completely new set of applicable rules for approval of the WPS prior to the its release to actual production. There are nine parts in this standard, covering the general rules applicable to fusion welding, welding of the aluminum and aluminum alloys, WPS for arc welding, various welding procedure tests applicable approval of the standard WPS, pipeline welding, offshore applications etc.​

This standard provides necessary requirements to runway beams constructed using the rolled steel sections. Suitability of some other materials might be considered, but the designed must note the particular mechanical properties of the materials proposed for use.

It shall be underlined that the main obligation of the tester is to get the actual runway tested as necessary; under no circumstances shall he himself that the structures and associated supports seem suitable for all loads they will be take. Sometimes, cases this may not be practicable; it will then be the responsibility of the purchaser, in consultation with the competent person, to satisfy the tester that the structure is suitable. The runway beams, i.e. constructions on which trolleys move, shall be of suitable size and adequate stress - they shall also have an even running surface.

The beams shall be adequately supported/suspended and, of course, they shall be capable of being duly maintained. When calculating stresses in the beams, the lifted load shall be taken into account as necessary, along with the weight of the beam and of the lifting appliance, force on the hand chain, and any other loads that are superimposed...

The present British Standard no. BS EN 10079:1993 fully dedicated to the popular definitions that are applicable to the various steel products, and superseding the previous version BS 6562-1:1986. For Normative references refer to the Annex A & B. Steel in the liquid state ready for pouring and obtained from the melting of raw material.

A distinction is made between following: — liquid steel for pouring into ingot moulds or for continuous casting; — liquid steel for castings. Here is the arrangement of this document: scope - normative references - liquid steel - ingots and semi-finished products - flat and long products - other products - steel products and associated standards - references, etc. There is a brief trilingual vocabulary provided - it allows reader to find get the terms translated from English to German and French languages.

There is a number of figures for illustration, such as the illustration of typical profile sheet and of typical sandwich panel, typical sheet piling, typical bearing piling, typical mining frame sections, typical heavy sections etc. Apart from that, numerous links have been provided to some other standards. Highly recommended regulatory paper for everyone wishing to have the idea of the European nomenclature of the steel products.
