9、s the further development and improvement of voluntary standardization in the national interest. The principal objects of the SCC are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety and welfare of the public, assisting and p
10、rotecting the consumer, facilitating domestic and international trade, and furthering international cooperation in the field of standards. A National Standard of Canada (NSC) is a standard prepared or reviewed by an accredited Standards Development Organization (SDO) and approved by the SCC accordin
11、g to the requirements of CAN-P-2. Approval does not refer to the technical content of the standard; this remains the continuing responsibility of the SDO. A NSC reflects a consensus of a number of capable individuals whose collective interests provide, to the greatest practicable extent, a balance o
12、f representation of general interests, producers, regulators, users (including consumers), and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard which is capable of making a significant and timely contribution to the national interest. Those who
13、have a need to apply standards are encouraged to use NSCs. These standards are subject to periodic review. Users of NSCs are cautioned to obtain the latest edition from the SDO which publishes the standard. The responsibility for approving National Standards of Canada rests with the: Standards Counc

29、 35.1.1 An extinguisher cylinder shall withstand for 1 minute, without rupture, a pressure of twice the proof test pressure as specified in 35.1.2 (a), (b), or (c) 35.1.2 The proof test pressure is to be determined as follows: a) For a hand-portable extinguisher that uses a single chamber for both t
30、he agent and expellant gas, the proof test pressure shall be three times the intended charging pressure at 21C (70F) except as provided in (b); b) For extinguishers of the wheeled type, the proof test pressure shall be twice the intended charging pressure at 21C (70F); and c) The minimum proof press
31、ure shall be twice the charging pressure or 800 kPa (120 psig), whichever is greater. 35.1.3 A non-metallic cylinder for a wheeled extinguisher shall withstand for 1 minute, without rupture, a pressure of six times, its intended charging pressure at 21C (70F). 35.1.4 There shall be no permanent volu
32、metric expansion in excess of 10 percent of the total expansion of the cylinder when pressurized to the proof test pressure as specified in 35.1.2 (a), (b), or (c) for 30 seconds, after which the pressure is to be released. For cylinders that have been proof pressure tested, the test pressure is to
33、be increased by 10 percent. 35.1.5 When an extinguisher cylinder tested to rupture (see 35.4.3), fractures along circumferential joints between the top or bottom dome and the side sheet, or at the collar or collar joint or at the point of attachment of elbows or discharge fittings, the rupture press
34、ure shall be a minimum eight times the operating pressure at 21C (70F). Fractures passing through welds but parallel to the longitudinal axis of the cylinder are to be evaluated according to the requirements specified in 35.1.1. For the purposes of this requirement the heat affected zone is consider
35、ed to be a part of the weld. 35.1.6 The flat dome or bottom of a cylinder shall withstand for 1 minute, without rupture, an internal pressure of eight times its intended charging pressure at 21C (70F). During this test, the cylinder sidewall is to be restrained with a close fitting steel sleeve or s
36、imilar device to prevent rupture of the sidewall.No Text on This Page Amendment 2 CAN/ULC-S507 ANSI/UL 626 March 30, 2012 36.1.3 Following the vibration test, the extinguisher shall discharge a minimum of 95 percent of its rated capacity of agent solution at 21 3C (70 5F). When there are visible sig
37、ns of damage or deterioration of the valve or cylinder, the extinguisher shall be subjected to and comply with the requirements of 35.1.1, 35.1.5 and 35.2.1. The minimum burst pressure for extinguishers with DOT or TDGR specification cylinders shall be four times the charging pressure at 21 C ( 70 F
38、). 37.2.1 A hand-portable extinguisher charged with its rated capacity shall comply with the requirements specified in (a) and (b) below after being dropped three times onto a concrete surface as specified in 37.2.2: a) The extinguisher shall not rupture. b) The extinguisher shall comply with the re
39、quirements specified in 35.1.0 and 35.1.1, except that the test pressure is to be equal to the rated charging or maximum operating pressure. 62.1 Cylinders 62.1.1 The cylinder of each extinguisher shall withstand for 30 seconds, without leakage, the proof pressure as specified in 35.1.2 (a), (b), or
40、 (c) as applicable. 62.1.1.1 Cylinders that are designed, tested, and marked in accordance with specifications for shipping containers of the DOT or TDGR shall comply with the applicable DOT or TDGR specification. 62.1.2 The apparatus for the pressure test is to consist of a hand- or motor-operated
41、pump capable of producing the required test pressure, fittings for attachment to the test sample, a pressure gauge graduated in increments of at least 138 kPa (20 psig), and the valves, fittings, and similar devices, for regulating and maintaining the specified pressure.

43、o be taken from a finished cylinder and selected so that each of the major welds is represented by a single sample. The samples then are to be prepared in accordance with “Practice A“ of Standard Practices for Detecting Susceptibility to Intragranular Attack in Austenitic Stainless Steels, ASTM A262
