This document specifies the mechanical, physical and optical characteristics of a 120 mm rewritable optical disk with a capacity of 100,0 Gbytes. It specifies the quality of the recorded and unrecorded signals, the format of the data and the recording method, thereby allowing for information interchange by means of such disks. User data can be written, read and overwritten many times using a…

This document specifies maximum and minimum dimensions for omega clamps (saddle clamps) installed by means of two bolts with nominal diameters of 5 mm. The specified dimensions define a dimensional envelope. This document is not an interchangeability standard. The tolerances for each type of clamp are defined in the drawings in the standards for parts.

This document specifies acceptance levels for indications from imperfections in butt welds of steel, nickel, titanium and their alloys detected by radiographic testing. If agreed, the acceptance levels can be applied to other types of welds (such as fillet welds, etc.) or materials. The acceptance levels can be related to welding standards, application standards, specifications or codes. This…

This document specifies acceptance levels for indications from imperfections in aluminium butt welds detected by radiographic testing. If agreed, the acceptance levels can be applied to other types of welds (such as fillet welds etc.) or materials. The acceptance levels can be related to welding standards, application standards, specifications or codes. This document assumes that the radiographic…

1 Scope 1.1 These requirements cover mechanical type accessories that are typically intended for attachment to storage tanks or connecting pipe for flammable and combustible liquids in commercial (public) or private (fleet) automotive fueling station and similar storage or dispensing applications and are designed to provide automatic safety or operational functions. 1.2 These products may be…

1.1 Scope ASME A17.8/CSA B44.8 applies to elevators permanently installed in a wind turbine tower to provide vertical transportation of authorized personnel and their tools and equipment only. Such elevators are typically subjected to extreme temperatures, humidity variations, and substantial horizontal motions where, by reason of their limited use and the types of construction of the…

1 Scope 1.1 General This Standard outlines minimum requirements and recommendations for the management of a stormwater system established by an operating authority. It provides a standardized guidance process to manage a stormwater system to meet regulatory requirements, reflect sound policy decision-making, and demonstrate a high standard of care to minimize legal, environmental, social, and…

1 Scope 1.1 This Standard covers fibrocement Type 1 (Class 3000) and Type 2 (Class 4000) pipe and pipe fittings for installation in storm and sanitary drainage systems for drain, waste, and vent (DWV) inside and outside of buildings, above and below grade. 1.2 This Standard includes specifications for material, dimensions, crushing strength, chemical resistance, and joint tightness. Methods…

Scope This standard defines Ethernet local area, access and metropolitan area networks. Ethernet is specified at selected speeds of operation; and uses a common media access control (MAC) specification and management information base (MIB). The Carrier Sense Multiple Access with Collision Detection (CSMA/CD) MAC protocol specifies shared medium (half duplex) operation, as well as full duplex…
