Standards
This specification covers two grades of kerosene suitable for use in critical kerosene burner applications: 1.1.1 No. 1-K—A special low-sulphur grade kerosene suitable for use in non-flue-connected kerosene burner appliances and for use in wick-fed illuminating lamps. 1.1.2 No. 2-K—A regular grade kerosene suitable for use in flue-connected burner appliances and for use in wick-fed illuminating lamps.
This specification is intended for use in purchasing, as a reference for industry and governmental standardization, and as a source of technical information.
This specification, unless otherwise provided by agreement between the purchaser and the supplier, prescribes the required properties of kerosene at the time and place of custody transfer.
Fuel meeting the requirements of this part of ISO 15403 should:
(a) provide for the safe operation of the vehicle and associated equipment needed for its fuelling and maintenance;
(b) protect the fuel system from the detrimental effects of corrosion, poisoning, and liquid or solid deposition;
(c) provide satisfactory vehicle performance under any and all conditions of climate and driving demands.
Some aspects of this part of ISO 15403 may also be applicable for the use of natural gas in stationary combustion engines.
a) Self-ballasted compact fluorescent lamps (CFL) of voltages > 50 V;
b) Integrated light-emitting diode lamps (LEDi) for stable operations, intended for domestic and similar general lighting purposes, having a:
1) rated power up to 60 W;
2) rated voltage of > 50 V a.c up to 250 V a.c.
This standard does not apply to semi-integrated (LEDsi) and non-integrated (LEDni) light-emitting diode lamps.
This document specifies chemical and labelling requirements for alcohol based hand sanitizers.
This standard applies to over-the-counter alcohol-based hand sanitizers.
This standard does not apply to:
a) Non-alcohol based hand sanitizers;
b) medical-grade hand sanitizers;
hand sanitizers used for
surgical application
This part of ISO/IEC 9314 specifies the Media access control (MAC) , the middle sublayer of the data link layer (DLL) for fiber distributed data interface (FDDI) .FDDI (ISO/IEC 9314) provides a high -bandwidth (100 Mbit/s).general - purpose interconnection among information processing systems, subsystems and peripheral equipment , using fiber optics or other transmission media. FDDI can be configured to support a sustained data transfer rate of at least 80 Mbit/s (10 Mbytes/s). FDDI provides connectivity for many nodes distributed over distances of many kilometers in extent . Certain default parameter values for FDDDI (e.g. timer settings) are calculated on the basis of up to 1000 transmission links or up to 200 km total fiber path length (typically corresponding to 5000 nodes and 100 km of dual fiber cable, respectively), however, the FDDI protocols can support much larger networks by increasing these parameter values.
This part of ISO/IEC 18026 provides an overview of different techniques of security gateways, of components and of different types of security gateway architectures, it also provides guidlines for selection and configuration of security gateways.
This part of ISO/IEC 20000 defines the requirements for a service provider to deliver managed services of an acceptable quality for its customers
This part of ISO/IEC 20000 represents an industry consensus on quality standards for IT service management processes . These service management processes deliver the best possible service to meet a customer's business needs within agreed resource levels, i.e. Service that is professional cost-effective and with risks which are understood and managed.
The fieldbus data link layer provide basic time-critical messaging communication between devices in an automation environment. The purpose of this part of IEC 61158 is to define eight distinct and non- interoperable fieldbus Data link protocols. Each protocol defined in this standard is most most closely related to and lies within the field of application of the corresponding services of IEC 61158-3. the fieldbus data link services definition .
This part of IEC 61850 specifies the specific communication service mappings for the communication between bay and process level and if specifies a mapping on a serial unidirectional multidrop point point to point link in accordance with IEC 60044-8. This part of IEC 61850 specifies a mapping of the abstract service for the transmission of sampled values ( as defined in IEC 61850-7-2 ) on a serial unidirectional multidrop point link in accordance with IEC 60044-8. It applies to the communication between merging units of electronic current (ECT) or voltage-transformers (EVT) and bay devices such as protection relays. If higher requirements on sampling rate. further sampling measured value data sets in addition to the universal data set. inter-bay communication and synchronization apply, these will be covered by IEC 61850-9-2 Figure 1 show the schematics of this interface.
