Expression of performance of sample handling systems for process analyzers
Specifies the tests which should be carried out to determine the functional performance of sample handling systems. In addition, specifies the information to be provided by the manufacturers and users of such systems. Applies to systems handling of gaseous or liquid samples for process analysers.
This standard establishes quality requirements for the soft cellular
polyurethane materials intended to resist repeated pressures. Polyurethane
foams are classified according to their type, density, firmness and burning
behaviour*.
This standard applies to polyurethane foams used for upholstery. It covers
foam blocks, those cut into different shapes (bands, sheets, etc.) as well as…
Design and Installation of Earth Energy Heat Pump Systems for Residential
and Other Small Building...
1.1
Applies to unitary or split system liquid source heat pumps with a maximum
standard rated output of 35 kW per unit for residential applications and other
small building applications of up to and including 1400 m² (15 000 ft²), using
surface or ground water or coupled to an earth or lake loop as a thermal source
or sink for the heating and/or cooling with or without a supplementary…
This National Standard of Canada is equivalent to American National Standards
Institute standard ANSI T1.408-1990.
1.1 General
It establishes performance and technical criteria for interfacing and
interconnecting the various functional groups shown in figure 1. Compliance
with this standard is intended to ensure compatibility at the interface points
/a and /b (figure 1) and should not…
Standard Practice for Dilute-Solution Viscosity of Photodegradable Polystyrene
Scope
Z217.1
1.1 This practice outlines a method for the determination of the dilute solution viscosity of polystyrene products in tetrahydrofuran (THF). It is applicable to nondegraded and photodegraded polystyrene samples. It is used for the determination of relative viscosity (viscosity ratio), inherent viscosity (logarithmic viscosity number), intrinsic viscosity (limiting…
Test Method for Tumbling Friability of Degradable Polystyrene Foams
1. Scope
1.1
This method determines the degradation of polystyrene foams by measuring mass
loss due to a combination of abrasion and impact produced by a laboratory
tumbling device.
1.2
The values stated in metric (SI) units are to be regarded as the standard. The
values in parentheses are provided for information only.
1.3
This Standard does not purport to address all of the…
Preface
The vent sizing Tables, published in 1992 as Amendments to the CAN/CGA-B149.1-M91 Natural Gas Installation Code, and CAN/CGA-B149. 2-M91 Propane Installation Code, contained new venting criteria for Category I type appliances. These same Tables (unchanged) were included in subsequent editions of the Codes (ie. CAN/CGA-B149.1-M95 and CAN/CGA-B149.2-M95) and have been adopted by all…
