Standard Specification for Transferring Digital Neurophysiological Data Between Independent Computer Systems (Withdrawn 2004)

Standard Specification for Transferring Digital Neurophysiological Data Between Independent Computer Systems (Withdrawn 2004)

SCOPE
1.1 This specification covers transmission of digitally recorded electrophysiologic waveform data and related textual annotations between laboratories or clinics, or between computer systems in a given laboratory or clinic. This includes all electroneurophysiology (EN) studies such as electroencephalograms (EEG) and magnetoencephalograms (MEG), polysomnograms (PSG) and multiple sleep latency tests (MSLT), evoked potentials (EP) and evoked magnetic fields (EMF), event-related potentials (ERP), electromyograms (EMG) and nerve conduction studies (NCS), and many others in either a clinical or research environment. Although this specification is concerned primarily with electroneurophysiology, the methods used for encoding waveform and related data would be suitable for other tests involving waveforms, such as electrocardiograms (EKG), vascular/intracranial pressure monitoring, oximetry, or gastrointestinal motility studies.
1.2 This specification defines a format for waveform data based on Specification E 1238 (developed in cooperation with HL7 (Health Industry Level 7)), with extensions to support the transmission of multichannel time-series waveforms.
1.3 This specification may be applied either to two-way transmission of data over medium- to high-speed data communication networks, or one-way transmission of data by recording on and later playback from magnetic or optical digital storage media. It defines the blocked stream of data, called a message, which is transmitted over a network connection or recorded on a storage medium. It does not define the hardware or software network protocols or storage media formats needed for message transmission (for example, see ISO 8072), or the formats used to store data internally by the sender or receiver.
1.4 Recognizing, however, that some standardization in storage media format and network protocols would help to promote exchange of data between computer systems with diverse hardware and software, it is suggested that readily available universal media and formats be used, when possible, for data exchange. An example suitable for transmission of large amounts of digital waveform data would be the use of industry-standard magnetic tape or digital audio tape (DAT), with ANSI standard tape labels, employing variable length blocked records (lines) with a maximum block size of 4092 bytes. Individual lines within the blocks would be terminated by carriage return characters, Code 13 in the American Standard Codes for Information Interchange (ASCII). As another example, for the transmission of moderate amounts of digital waveform data, floppy disks written in MS-DOS (1) format (or another commonly used directory and file structure) would be appropriate; the data would be contained within a single sequential file on the disk, with lines within the file delimited by carriage return (ASCII 13) or carriage return followed by linefeed (ASCII 10) characters. An example of network hardware and software suitable for transmission of waveform data would be Ethernet (2)and the TCP/IP (3)protocol.
NOTE: This page does not contain the complete scope (section 1.5). To see scope in it's entirety please refer to the standard.

Standard Test Methods and Definitions for Mechanical Testing of Steel Products

SIGNIFICANCE AND USE
4.1 The primary use of these test methods is testing to determine the specified mechanical properties of steel, stainless steel, and related alloy products for the evaluation of conformance of such products to a material specification under the jurisdiction of ASTM Committee A01 and its subcommittees as designated by a purchaser in a purchase order or contract.  
4.1.1 These test methods may be and are used by other ASTM Committees and other standards writing bodies for the purpose of conformance testing.  
4.1.2 The material condition at the time of testing, sampling frequency, specimen location and orientation, reporting requirements, and other test parameters are contained in the pertinent material specification or in a general requirement specification for the particular product form.  
4.1.3 Some material specifications require the use of additional test methods not described herein; in such cases, the required test method is described in that material specification or by reference to another appropriate test method standard.  
4.2 These test methods are also suitable to be used for testing of steel, stainless steel and related alloy materials for other purposes, such as incoming material acceptance testing by the purchaser or evaluation of components after service exposure.  
4.2.1 As with any mechanical testing, deviations from either specification limits or expected as-manufactured properties can occur for valid reasons besides deficiency of the original as-fabricated product. These reasons include, but are not limited to: subsequent service degradation from environmental exposure (for example, temperature, corrosion); static or cyclic service stress effects, mechanically-induced damage, material inhomogeneity, anisotropic structure, natural aging of select alloys, further processing not included in the specification, sampling limitations, and measuring equipment calibration uncertainty. There is statistical variation in all aspects of mechanical testin...
SCOPE
1.1 These test methods2 cover procedures and definitions for the mechanical testing of steels, stainless steels, and related alloys. The various mechanical tests herein described are used to determine properties required in the product specifications. Variations in testing methods are to be avoided, and standard methods of testing are to be followed to obtain reproducible and comparable results.

Test Method for Shrinkage Temperature of Wet Blue and Wet White

SIGNIFICANCE AND USE
5.1 This test method is designed to determine the temperature at which the Wet Blue or Wet White specimen experiences shrinkage. In this test method, shrinkage occurs as a result of hydrothermal denaturation of the collagen protein molecules which make up the fiber structure of the Wet Blue or Wet White. The shrinkage temperature of Wet Blue or Wet White is influenced by many different factors, most of which appear to affect the number and nature of crosslinking interactions between adjacent polypeptide chains of the collagen protein molecules. The value of the shrinkage temperature of Wet Blue or Wet White is commonly used as an indicator of the type of tannage or the degree of tannage, or both, of that particular Wet Blue or Wet White (especially for the more hydrothermally stable tannages such as chrome tannage).
SCOPE
1.1 This test method covers the determination of the shrinkage temperature of all types of Wet Blue and Wet White. The heating medium is water when the shrinkage temperature is at or below 98 °C. The heating medium is a glycerine-water solution when the shrinkage temperature is above 98 °C.  
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Guide for Selection of Test Methods for Ethylene Propylene Diene Terpolymer (EPDM) Geomembranes

SIGNIFICANCE AND USE
4.1 This standard provides guidance to obtain data that is the most representative of the material’s characteristics and performance. To properly evaluate EPDM, tests should be performed in accordance with specific test methods and procedures.
SCOPE
1.1 This guide covers and provides recommendations for the selection of appropriate test methods for Ethylene Propylene Diene Terpolymer (EPDM) geomembranes used in geotechnical and geoenvironmental applications.  
1.2 This guide includes test methods for three different types of EPDM geomembranes including: scrim-reinforced membranes, composite membranes, and smooth, nonreinforced membranes.  
1.3 The test methods are divided into three categories including manufacturing quality control, optional performance tests, and seam testing.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
