This International Standard is used to determine the degree of disintegration of plastic materials in a pilot-scale aerobic composting test under defined conditions. The test method laid down in this standard can also be used to determine the influence of the test material on the composting process and the quality of the compost obtained. It cannot be used to determine the aerobic…

ISO 17591 defines identifying terms, specifies a means of classification and gives a nomenclature of components for the knuckleboom log loader machinery used in forestry. Its aim is to establish a uniform method of describing the various configurations of this type of mobile forest machine.

This standard defines the mechanical, electrical, timing, and protocol requirements of the SCSI parallel interface to allow conforming SCSI devices to inter-operate. The SCSI parallel interface is a local I/O bus that may be operated over a wide range of transfer rates. The objectives of the SCSI parallel interface are:a) To provide host computers with device independence within a class of…

ISO/IEC 8348:2002 defines the set of capabilities, in terms of abstract service definition, provided by the Network Layer to the Transport Layer. For designers of Transport Layer protocols, it provides a definition of the Network service to allow design and implementation independent of details of the Network Layer protocol. For designers of Network Layer protocols, it defines the set of…

This part of ISO 230 specifies diagonal displacement tests which allow the estimation of the volumetric performance of a machine tool. Complete testing of the volumetric performance of a machine tool is a difficult and time-consuming process. Diagonal displacement tests reduce the time and cost associated with testing the volumetric performance. A diagonal displacement test is not in itself a…

ISO 2639 defines the case-hardened depth, and specifies methods for the determination of this depth, in steel. It is applicable to carburized cases and carbonitrided cases;parts that, when heat treated to final hardness, have a hardness of less than 450 HV 1 at a distance of three times the case-hardened depth, from the surface. The case-hardened depth is defined by special agreement where these…

1. Scope This Standard defines technical and ergonomic requirements for pay telephone keypads and function keys, with particular regard to the needs of persons with disabilities, to enable users to locate, identify, and operate the keys necessary to place phone calls. Note: While the purpose of this Standard is to make the product more usable, there may be some persons with disabilities who…

1. SCOPE 1.1 This standard applies to task chairs for office work with Visual Display Terminals (VDT) by providing dimensional and adjustment requirements. This standard also defines test methods for measuring chairs and assessing their performance. 1.2 This standard also provides for dimensional and adjustment requirements that respect gerally acceptable ergonomic guidelines such as those…
