- Inactive - Superseded. This Local and Metropolitan Area Network standard, ISO/IEC 8802-5 :1992, is part of a family of local area network (LAN) standards dealing with the physical and data link layers as defined by the ISO Open System Interconnection Reference Model. Its purpose is to provide compatible interconnection of data processing equipment by means of a local area network using the token-passing ring access method. The frame format, including delimiters, addressing, and frame-check sequence, are defined, and medium access control (MAC) frames, timers, and priority stacks are defined. The MAC protocol is defined. The finite-state machine and state tables are supplemented with a prose description of the algorithms. The physical layer (PHY) functions of symbol encoding and decoding, symbol time, and latency buffering are defined. The services provided by the MAC to the station management (SMT) and the services provided by the PHY to SMT and the MAC are described. These services are defined in terms of service primitives and associated parameters. The 4 and 16 Mb/s, shielded twisted pair attachment of the station to the medium, including the medium interface connector (MIC) are also defined. The applications environment for the LAN is intended to be commercial and light industrial. The use of token ring LANs in home and heavy industrial environments, while not precluded, has not been considered in the development of the standard. A Protocol Implementation Conformance Statement (PICS) proforma is provided as an annex to the standard

The use of mixed gas working fluids has become common in Joule–Thomson typecryocoolers for a variety of applications. However, there is a scarcity of data currently availablewith supporting theory capable of predicting the heat transfer coefficients associated with twophase,multi-component mixtures at cryogenic temperatures. This document describes anexperimental facility designed and constructed to measure the heat transfer coefficients andfrictional pressure drop in small diameter, horizontal test sections with two-phase, multicomponentzeotropic mixtures at cryogenic temperatures. The aim of this facility is to enable thecollection of high accuracy data to overcome the scarcity of heat transfer and pressure drop datafor zeotropic mixtures undergoing a phase change (boiling). Results are available forhydrocarbon mixtures (comprised of methane, ethane, and propane) and synthetic refrigerantmixtures (including R14, R23, R32, and R134a), which are commonly used in small Joule–Thomson cryocoolers. The measured heat transfer coefficients for hydrocarbon and syntheticmixtures included nitrogen and argon, respectively for dilution.

MPIF Standard 35 is issued to provide the design and materials engineer with the information necessary for specifying powder metallurgy (PM) materials that have been developed by the PM parts manufacturing industry. This section of Standard 35 deals with conventional PM materials for structural parts. It does not apply to materials for PM self-lubricating bearings, powder forged (PF) or metal injection molded (MIM) products which are covered in separate editions of MPIF Standard 35. The same materials may appear in more than one section of the standard depending upon their common use, e.g., some structural materials may also be used in bearing applications and vice versa. Each section of this standard is divided into subsections based on the various types of PM materials in common commercial use within that section. Notes at the beginning of each subsection discuss the characteristics of that material. Users of this standard should make a determination as to the availability of any referenced material.

New IEEE Standard - Unapproved Draft. This standard establishes uniform procedures for the measurement of radio noise generated by corona from overhead power lines. Measurement procedures in this standard are also valid for other power-line noise sources such as gaps and harmonics; however, most of the precautionary information, analysis, and data plotting techniques were written and developed primarily for corona discharges. The procedures are not valid for measuring transient radio noise sources that occur during breaker or disconnect switching operations. The procedure applies in the frequency range of 0.010-1000 MHz; however, the emphasis is on the standard amplitude modulation broadcasting (0.535-1.605 MHz) and television broadcasting (54-72 MHz, 76-88 MHz, 174-216 MHz, and 470-698 MHz) bands. This standard is applicable to both ac and dc transmission lines and substations.

ASTM D6839-16 : Standard Test Method for Hydrocarbon Types, Oxygenated Compounds, and Benzene in Spark Ignition Engine Fuels by Gas Chromatography

May 2, 2016, 3:09 am

≫ Next: ASTM D7845-16 : Standard Test Method for Determination of Chemical Species in Marine Fuel Oil by Multidimensional Gas Chromatography/Mass Spectrometry

≪ Previous: 2017 National Electrical Safety Code(R) and Handbook Set

1.1 This test method covers the quantitative determination of saturates, olefins, aromatics, and oxygenates in spark-ignition engine fuels by multidimensional gas chromatography. Each hydrocarbon type can be reported either by carbon number (see Note 1) or as a total.

Note 1: There can be an overlap between the C₉ and C₁₀ aromatics; however, the total is accurate. Isopropyl benzene is resolved from the C₈ aromatics and is included with the other C₉ aromatics.

1.2 This test method is not intended to determine individual hydrocarbon components except benzene.

1.3 This test method is divided into two parts, Part A and Part B.

1.3.1 Part A is applicable to automotive motor gasoline for which precision (Table 9) has been obtained for total volume fraction of aromatics of up to 50 %; a total volume fraction of olefins from about 1.5 % up to 30 %; a volume fraction of oxygenates, from 0.8 % up to 15 %; a total mass fraction of oxygen from about 1.5 % to about 3.7 %; and a volume fraction of benzene of up to 2 %. Although this test method can be used to determine higher-olefin contents of up to 50 % volume fraction, the precision for olefins was tested only in the range from about 1.5 % volume fraction to about 30 % volume fraction. The method has also been tested for an ether content up to 22 % volume fraction but no precision data has been determined.

1.3.1.1 This test method is specifically developed for the analysis of automotive motor gasoline that contains oxygenates, but it also applies to other hydrocarbon streams having similar boiling ranges, such as naphthas and reformates.

1.3.2 Part B describes the procedure for the analysis of oxygenated groups (ethanol, methanol, ethers, C₃ to C₅ alcohols) in ethanol fuels containing an ethanol volume fraction between 50 % and 85 % (17 % to 29 % oxygen). The gasoline is diluted with an oxygenate-free component to lower the ethanol content to a value below 20 % before the analysis by GC. The diluting solvent should not be considered in the integration, this makes it possible to report the results of the undiluted sample after normalization to 100 %.

1.4 Oxygenates as specified in Test Method D4815 have been verified not to interfere with hydrocarbons. Within the round robin sample set, the following oxygenates have been tested: MTBE, ethanol, ETBE, TAME, iso-propanol, isobutanol, tert-butanol and methanol. The derived precision data for methanol do not comply with the precision calculation as presented in this International Standard. Applicability of this test method has also been verified for the determination of n-propanol, acetone, and di-isopropyl ether (DIPE). However, no precision data have been determined for these compounds.

1.4.1 Other oxygenates can be determined and quantified using Test Method D4815 or D5599.

1.5 The method is harmonized with ISO 22854.

1.6 This test method includes a relative bias section for U.S. EPA spark-ignition engine fuel regulations for total olefins reporting based on Practice D6708 accuracy assessment between Test Method D6839 and Test Method D1319 as a possible Test Method D6839 alternative to Test Method D1319. The Practice D6708 derived correlation equation is only applicable for fuels in the total olefins concentration range from 0.2 % to 18.2 % by volume as measured by Test Method D6839. The applicable Test Method D1319 range for total olefins is from 0.6 % to 20.6 % by volume as reported by Test Method D1319.

1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.8 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 and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This test method covers the quantitative determination of a variety of chemical species in marine fuel oil (bunker fuel oil) by gas chromatography/mass spectrometry. By using the same conditions and by selecting required mass spectral selected ions, the test method may be used for the determination of other species than those for which precision statements and limits of detection have been established.

1.2 An example list of chemical species for which a limit of quantification has been determined by means of this test method is given in Table 1.

1.3 Other refinery hydrocarbon fractions and their mixtures may be tested using the same test method conditions. However, the precision of this test method reflects the compounds in Table 1.

1.4 Results are reported to the nearest 1.0 mg/kg.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 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 and health practices and determine the applicability of regulatory limitations prior to use.
