APPENDIX A

1. TEST METHOD

Each cylinder or tube shall be visually inspected externally and be subjected to an acoustic emission test and, when required, to a follow-up visual and ultrasonic examination.

1.1 Applicable Standards

CAN/CSA-B339-02, Cylinders, Spheres, and Tubes for the Transportation of Dangerous Goods, October 2002, as amended in November 2003 and

February 2005 (CAN/CSA-B339-02).

Compressed Gas Association Inc. (CGA) Publication C-6-2007, Standards for Visual Inspection of Steel Compressed Gas Cylinders, dated 2007 (CGA C‑6‑2007).

CAN/CGSB-48.9712-2006, Non-destructive Testing - Qualification and Certification of Personnel, dated March 2006 (CAN/CGSB-48.9712-2006).

ASTM E650-97(2007), entitled, Standard Guide for Mounting Piezoelectric Acoustic Emission Sensors, dated 1997, and reapproved in 2007.

ASTM A388 / A388M 11 entitled, Standard Practice for Ultrasonic Examination of Steel Forgings, dated 2011.

2 VISUAL EXAMINATION

Each cylinder or tube shall be visually inspected externally, in accordance with

CGA C-6 2007.

3 ACOUSTIC EMISSION TEST

3.1 Scope of test

The entire container under test shall be monitored using two transducers mounted at its extremities. The transducers shall be at the same angular location and approximately 25 mm from the tangent point at the container shoulder.

Issue Date: March 1, 2012

Equivalency Certificate

SU 6077 (Ren. 4)

APPENDIX A

3.2 Transducer coupling

Transducers shall be coupled acoustically to the container using a viscous or solid couplant and held in place by suitable holders in accordance with

ASTM E650-97(2007).

3.3 Calibration

The system shall be calibrated and checked using a signal generated by a pulser or by breaking a pencil lead on the surface of the container. When done by breaking a pencil lead, a Pentel 2H, 0.5 mm diameter, 3 mm long lead shall be used. When done using a pulser, the ultrasonic pulse intensity at one meter from the pulser shall be equal to that of the pencil lead break. The sensitivity of each channel shall be checked by generating a calibration signal in proximity to each sensor and ensuring that the measured peak amplitude is greater than 80 dB. The instrument settings on each channel shall also be set to ensure that a pencil break introduced adjacent to one transducer is detected at the other with minimum noise. The precision and accuracy of the location function shall be recorded at the center of the container between the transducers and meet the manufacturer's specified accuracy of the instrumentation.

3.4 Pressurization

A method shall be provided to continuously read the container pressure. Pressure shall be applied monotonically from zero to 110% of usual settled fill pressure or 110% of service pressure, whichever is greater. Acoustic emissions shall be monitored during pressurization by observing the displays of events versus location. Acoustic emissions shall be recorded starting when container pressure reaches 60% of usual settled fill pressure or 6.9 MPa, whichever is less, and continuing until pressurization is complete.

3.5 Interpretation of Results

The distribution of acoustic emission events versus axial location on each container shall be examined. The container shall be subjected to a follow-up examination as described in section 3.6 of this appendix, when:

(a) five or more acoustic emission events occur on the cylindrical portion of the container within a 200 mm axial segment; or

Issue Date: March 1, 2012

Equivalency Certificate

SU 6077 (Ren. 4)

APPENDIX A

(b) five or more acoustic emission events detected at both transducers occur on any container end outboard of the transducers

3.6 Follow-up Examination

Each axial container segment and end, where the rate of acoustic emission meets the criteria described in section 3.5 of this appendix, shall be subjected to a follow-up external visual and ultrasonic inspection of its entire surface, including an extension of 457 mm beyond either side of the axial container segment (on the cylindrical portion) or the entire end of the container within 457 mm of the segment, as applicable. The ultrasonic examination shall be performed in accordance with ASTM A388/A388M-11 by personnel certified to Level II or III in accordance with CAN/CGSB-48.9712-2006, or the equivalent, to detect and characterize the flaw. The container shall be rejected where the flaw is found to have a depth greater than or equal to the values specified in Table 1.
