This Recommendation | International Standard defines the Message Store abstract-service. This abstract-service is provided by the Message Store access protocol (specified in ITU-T Rec. X.419 | ISO/IEC 10021-6) in conjunction with the MTS abstract-service (defined in ITU-T Rec. X.411 | ISO/IEC 10021-4), together with the Remote Operations Service Element (ROSE) services (defined in ITU-T Rec. X.…

This Recommendation | International Standard is one of a series on message handling. The entire set provides a comprehensive blueprint for a Message Handling System (MHS) realized by any number of cooperating open systems. The purpose of an MHS is to enable users to exchange messages on a store-and-forward basis. A message submitted on behalf of one user, the originator, is conveyed by the…

This Recommendation | Technical Report specifies the means by which the administrator of various aspects of an MHS system may configure information into the directory for MTAs to use to determine the routing of messages. ITU-T Rec. X.412 | ISO/IEC 10021-10 provides a set of directory structures that may be configured in many different ways to support a particular MHS routing strategy. In order to…

This International Standard specifies requirements for fusion-bonded epoxy-coated post-fabricated and prefabricated steel bar, wire and welded fabric for the reinforcement of concrete. This International Standard permits the application of either flexible (type A) or nonflexible (type B) coatings. Steel reinforcing bar, wire and welded fabric coated with a nonflexible (type B) coating shall not…

This International Standard specifies the general requirements and limit dimensions of inch series UNJ threads with controlled root radius for aerospace construction. It determines the basic triangular profile for this type of thread and gives a system for designating the diameter and number of threads per inch combinations. For all diameters 0,060 in (1,524 mm) to 6,000 in (152,4 mm), it offers…

1. Scope 1.1 This Standard specifies energy performance requirements for self-contained drinking-water coolers having an hourly rated capacity of up to 20 mL/s (20 Us gal/h). Included are (a) uniform procedures for measuring capacity and energy consumption; and (b) maximum energy consumption levels. 1.2 This Standard applies to the following mechanical, thermoelectric, and other…

This International Standard specifies the logical specifications of STbus which is a highperformance and highly reliable system bus. STbus adopts a synchronous transfer method with a high-speed clock and a split transfer method enabling to minimize bus holding time during one bus operation and to use a bus efficiently. The contents given in this specifications are as follows: a) System bus…

Describes the measurement of screening attenuation by the reverberation, or stirred, chamber, suitable for virtually any type of microwave component and having no theoretical upper frequency limit. It is only limited toward low frequencies due to the size of the test equipment, which is frequency dependent and is only one of several methods of measuring sreening attenuation. For the purpose of…

1. Scope 1.1 This Standard outlines requirements and classifications for automatic and manual descent control devices intended for use in the workplace. These devices are not used for fall arrest. Appropriate fall protection equipment is also required in the presence of a fall hazard, except in the case of emergency egress. 1.2 This Standard applies to equipment intended to be used…

1. SCOPE 1.1 This standard applies to a flat latex paint for most interior walls and ceilings, with the exception of bathrooms and kitchens, either new or previously painted. 1.2 The paint is suitable for application over all types of wall surfaces, including wallboard, gypsum board, dry plaster, cement, brick or concrete block. 1.3 The testing and evaluation of a product…
