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…

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…

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…

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…

This National Standard of Canada is equivalent to International Standard ISo 4217:1990. This International Standard provides the structure for a three-letter alphabetic code and an equivalent three-digit numeric code for the representation of currencies and funds. For those currencies having minor units, it also shows the decimal relationship between such units and the currency itself…
