Standard for Thermal Insulation - Spray Applied Rigid Polyurethane Foam, MediumDensity, Material - S...
1. SCOPE
1.1
This Standard provides the requirements and test methods for spray-applied
rigid polyurethane cellular plastics, medium density, used as a thermal
insulation for both building and non-building applications, whether applied on
a building site or in a prefabrication (manufacturing) facility. The material
is also known as foamed in-situ insulation.
1.2
The spray-applied…

1.1
The main intent of this document is to provide accurate and consistent
terms used in the Canadian Thermal Insulation industry. More specifically, the
application of the information contained in this Standard is for reference use
with the Thermal insulation series of Standards, ULC-S700.
Safety of power transformers, power supply units and similar devices - Part 2-12: Particular require...
This part 2 of IEC 61558 is intended to be used in conjunction with IEC 61558-1.
This international standard deals with all aspects of safety such as electrical, thermal and mechanical.
This part of IEC 61558 applies to stationary or portable, single-phase or polyphase, air-cooled (natural or forced), associated or independent:
- constant voltage auto-transformers;
- constant voltage…
Distribution automation using distribution line carrier systems - Part 5-4: Lower layer profiles - M...
Is a technical specification describing the requirements of the multicarrier modulation approach which incorporates the services provided by the physical layer entity and the MAC sublayer with the purpose of building up a set of standards for effective communication on MV and LV network for distribution line carrier systems, in the context of IEC 61334-1-1.

Behavioural languages - Part 3-2: Mathematical operation in VHDL
This set of packages provides a standard for the declaration of most frequently used real and complex elementary functions required for numerically oriented modeling applications. Use of these packages with their defined data types, constants, and functions is intended to provide a mechanism for writing VHDL models (compliant with IEEE Std 1076-1993) that are portable and interoperable with other…
Behavioural languages - Part 3-3: Synthesis in VHDL
This standard supports the synthesis and verification of hardware designs, by defining vector types for representing signed or unsigned integer values and providing standard interpretations of widely used scalar VHDL values. Includes package bodies, as described in annex A, which are available in electronic format either on a diskette affixed to the back cover, or as a downloadable file from the…
Natural gas — Determination of potential hydrocarbon liquid content — Gravimetric methods
This International Standard describes the principles of, and general requirements for, two gravimetric methods for
the determination of the potential hydrocarbon liquid content of natural gas, or similar gas, at a given pressure and
temperature. Two methods are specified in this International Standard to determine the amount of condensate in a
sample gas:
_ Method A: a manual weighing method;
_…
1.1 This International Standard specifies the requirements for design and construction of piping for the petroleum and natural gas industries, including associated inspection and testing.
1.2 This International Standard is applicable to all piping within facilities engaged in the processing or handling of chemical, petroleum, natural gas or related products.
