Standard Practice for Preparing Specimens of Hydraulic Erosion Control Products for Index Property Testing

Published by: 2017-02-15 / 2017-02-15 / 3 pages

1.1 This practice specifies a set of instructions for preparing samples of hydraulic erosion control products (HECPs) for index property testing.

1.2 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.

1.2.1 For purposes of comparing measured or calculated value(s) with specified limits, the measured or calculated value(s) shall be rounded to the nearest decimal or significant digits in the specified limits.

1.2.2 The procedures used to specify how data are collected/recorded or calculated, in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be measured. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the users objectives; and it is common practice to increase or reduce the significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in the analytical methods for engineering design.

1.3 Units-The values stated in SI units are being regarded as standard. No other units of measurement are included in the practice.

1.4 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.

Performance Characterization of Electrified Powertrain Motor-drive Subsystem

Published by: 2017-02-15 / 2017-02-15
This document was developed to provide a method of obtaining repeatable measurements that accurately reflects the performance of a propulsion electric drive subsystem, whose output is used in an electrified vehicle regardless of complexity or number of energy sources. The purpose is to provide a familiar and easy-to-understand performance rating. Whenever there is an opportunity for interpretation of the document, a good faith effort shall be made to obtain the typical in-service performance and characteristics and avoid finding the best possible performance under the best possible conditions. Intentional biasing of operating parameters or assembly tolerances to optimize performance for this test shall not be considered valid results in the scope of this document.

IEC 62035 Ed. 2.0 b:2014

Discharge lamps (excluding flourescent lamps) – Safety specifications

Published by: 2014-04-10 / 2014-04-10 / 95 pages
IEC 62035:2014 specifies the safety requirements for discharge lamps (excluding fluorescent lamps) for general lighting purposes. This second edition cancels and replaces the first edition published in 1999, AMD1:2003 and AMD2:2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition. Photobiological safety requirements are taken care of on basis of the risk group concept of IEC 62471 and the technical report IEC TR 62778 on blue light hazard. This has consequences for terms, marking, structure of 4.6, and introduction of a new symbol "Caution, do not stare at light source". Special attention is given to blue light hazard. This bilingual version (2016-11) corresponds to the monolingual English version, published in 2014-04. The French version of this standard has not been voted upon.

LV-17-C026 — The Development of the Database of the Equipment Characteristics for the Building Energy Simulation Tool

Customers Who Bought This Also Bought

Published by: 2017-01-01 / 2017-01-01 / 8 pages

The database of the equipment characteristics provided by the BEST (Building Energy Simulation Tool) program is a flexible and expandable data set in which interactions among building equipments are well considered. These characteristic databases are always maintained in the neutral and fair way by the five subcommittee which are not affected by any specific manufacturer. The BEST program is designed to express every model in modules and can create various system configurations like major simulation tools such as TRNSYS and EnergyPlus. In this paper, the importance of modifiability of equipment databases, the expandability of the BEST program’s equipment databases, and the details of developing equipment characteristic databases are explained.

And, the methods to apply equipment characteristics based on other standards are also introduced. This database has three data sets (nominal performance characteristics, part load performance characteristics, and dynamic performance characteristics) which are solved by applying two modelling methods (empirical model and/or physics-based model) to represent equipment characteristics to provide shorter calculation cycles in the coupled calculation within the entire building calculation. Users will be able to run the simulations just by choosing and entering general informations of the equipments which are available from catalogs. In addition, more advanced equipment characteristics (e.g. heat pump utilizing renewable energy) are also prepared in this development.

ASTM D425-17

Standard Test Method for Centrifuge Moisture Equivalent of Soils

Published by: 2017-01-15 / 2017-01-15 / 5 pages

1.1 This test method covers the determination of the moisture equivalent of soil in the laboratory by means of a centrifuge technique.

1.2 This test method is limited to specimens of coarse-grained sandy soils having a maximum particle size of less than 2.00 mm and with fines of low plasticity. Soils having a unified soil classification, based upon procedures outlined in Practice D2488 such as SP, SW, SC-SM, or SM are considered acceptable for the test method.

1.2.1 For soils that are predominantly fine-grained, coarse-grained soils with medium to high plasticity, intact specimens or soils being tested at a specific density or unit weight refer to Test Methods D6836.

1.3 This test method is intended to be performed in a constant temperature environment. Variations in temperature exceeding the range outlined in 8.7 may influence the test data.

1.4 Units-The values stated in SI units are to be regarded as the standard except for sieve designations, which also include the “alternative” system in accordance with E11.

1.5 All recorded and calculated values shall conform to the guide for significant digits and rounding established in Practice D6026.

1.6 The procedures used to specify how data are collected/recorded and calculated in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining data, special purpose studies, or any considerations for the user's objectives; and it is common practice to increase or reduce significant digits of reported data to commensurate with these considerations. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design.

1.7 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.
