Guidance on clearances and creepage distances in particular for distances equal to or less than 2 mm. Test results of research on influencing parameters

Published by: 2016-10-31 / 2016-10-31 / 38 pages
BS PD IEC/TR 63040:2016 describes test results of research on dimensioning of clearances and creepage
distances, for spacing equal to or less than 2 mm for printed wiring material and other
equivalent arrangements of insulation, where the clearance and the creepage distance follows
the same path along the surface of solid insulation.

The information contained in this document is the result of research only and cannot be used
for dimensioning the clearances and creepage distances for equipment within low-voltage
systems, where IEC 60664-1 applies. However distances can be taken into account for
functional reasons.

This document provides results of research related to the following criteria:

  • clearances independent from the micro-environment;
  • creepage distances for pollution degree 1, 2 and 3 which extends the use of smaller
    distances to products having design features similar to printed circuit boards;

  • creepage distances to avoid flashover of the insulating surface;
  • information on minimum creepage distances to maintain minimum insulation resistance.

A test method for the evaluation of the relevant water adsorption group for the surface of any
insulating material which has not yet been classified is described.

IEEE Draft Guide for Conducting a Transient Voltage Analysis of a Dry-Type Transformer Coil

Published by: / 31 pages

Scope

This guide applies to the equipment setup, measurement, and analysis of the transient voltage response of a dry-type transformer coil to impulse voltage.

Purpose

Transient voltage analysis is used to determine the response of various parts of the coil to a 1.2 x 50 microsecond impulse wave. This analysis can be made on specially designed prototype coils with imbedded voltage leads. This testing uses significantly lower voltages than the rated Basic Lightning Impulse Insulation Level (BIL) to expedite the test time for each data point required.

Abstract

Revision Standard – Unapproved Draft.

General recommendations for measuring voltage transients in dry-type distribution and power transformers are provided. Recurrent surge voltage generator circuitry, instrumentation, test sample, test point location, mounting the test coil, conducting the test, and reporting results are covered.

Published by: 2016-01-01 / 2016-01-01 / 8 pages

All Gulf Cooperation Council (GCC) countries are listed in the top 20 countries for highest annual energy consumption and CO2 emissions per capita. In the past few decades, numerous residential projects constructed in the region have led to higher energy demand for the residential sector. In addition, the growing rate of urbanization and changes in lifestyles caused a significant increase in domestic energy consumption and in Oman, during the period from 2012 to 2018, peak electricity demand is expected to grow at 8% per year compared to the global average rate of 2.5%. This rapid increase in energy consumption has highlighted the need for energy solutions to overcome its excessive consumption. Since the residential sector consumes 48% of total electricity, the main source of energy in Oman, reducing domestic energy use has the potential to reduce the country’s total energy consumption. This research aims to evaluate experimentally the key Low Carbon Building (LCB) strategies and criteria best suited to the economic, climatic and social constraints for the hot humid climate of Oman that can be implemented in their future residential sector. For the purpose of this research, the energy performance of reference exemplar state of the art low carbon buildings available in the country, will be compared to selected examples of conventional buildings located within 15 km from the reference buildings. Six key performance parameters of energy consumption in the LCB; lighting, domestic electronic appliances, air conditioning (HVAC), hot water, refrigerators and wash machine, were monitored and recorded, whereas the energy consumption for the same parameters in the conventional buildings were calculated by energy audit. Building energy consumption patterns and performance were monitored and calculated. Based on the data collected, the domestic building energy consumption and energy performance index (EPI) for residential buildings were calculated. Then the modeled energy saving and CO2 emission reductions that may be achieved by implementing LCB strategies on conventional building were evaluated using IES virtual environment software.

Standard Guide for Accelerated Aging of Sterile Barrier Systems for Medical Devices

Published by: 2016-09-15 / 2016-09-15 / 7 pages

1.1 This guide provides information for developing accelerated aging protocols to rapidly determine the effects, if any, due to the passage of time on the sterile integrity of the sterile barrier system (SBS), as defined in ANSI/AAMI/ISO 11607-1:2006 and the physical properties of their component packaging materials.

1.2 Information obtained using this guide may be used to support expiration date claims for medical device sterile barrier systems.

1.3 The accelerated aging guideline addresses the sterile barrier systems in whole with or without devices. The sterile barrier system material and device interaction compatibility that may be required for new product development or the resulting evaluation is not addressed in this guide.

1.4 Real-time aging protocols are not addressed in this guide; however, it is essential that real-time aging studies be performed to confirm the accelerated aging test results using the same methods of evaluation.

1.5 Methods used for sterile barrier system validation, which include the machine process, the effects of the sterilization process, environmental challenge, distribution, handling, and shipping events, are beyond the scope of this guide.

1.6 This guide does not address environmental challenging that stimulates extreme climactic conditions that may exist in the shipping and handling environment. Refer to Practice D4332 for standard conditions that may be used to challenge the sterile barrier system to realistic extremes in temperature and humidity conditions. See Terminology F1327 for a definition of “environmental challenging.”

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.

JEDEC JESD232AA

Graphics Double Data Rate (GDDR5X) SGRAM Standard

Published by: 2016-08-01 / 2016-08-01 / 160 pages
This document defines the GDDR5X SGRAM memory standard, including features, device operation,
electrical charactersitics, timings, signal pin assignments and package.

The purpose of this standard is to define the minimum set of requirements for JEDEC standard compatible
4 Gb through 16 Gb x32 GDDR5X SGRAM devices. System designs based on the required aspects of this
standard will be supported by all GDDR5X SGRAM vendors providing JEDEC standard compatible
devices. Some aspects of the GDDR5X standard such as AC timings were not standardized. Some features
are optional and therefore may vary among vendors. In all cases, vendor data sheets should be consulted
for specifics.

This standard was created based on the GDDR5 SGRAM standard (JESD212). Each aspect of the changes
were considered and balloted. The accumulation of these ballots were then incorporated to prepare this
GDDR5X SGRAM standard.
