(e) the shell and heads are made of normalized ASTM A516 grade 70 steel and have a thickness equal to or greater than 32.0 mm (1.26 in.) after rolling and forming;

(f) the tank car is equipped with a full-head protection shield on each end of the tank car that is made from steel that has a minimum specified tensile strength equal to or greater than 380 MPa (55 000 psi) and has a thickness equal to or greater than 12.7 mm (0.5 in.), shaped to the contour of the tank‑head;

(g) the tank car has a maximum gross mass on rail equal to or less than 130 000 kg (286 000 lb.);

(h) any tank car with a gross mass greater than 119 300 kg (263 000 lb.) must meet the requirements of Association of American Railroads (AAR) standard S‑286;

(i) the outage of any tank car measured at 46°C (115°F) is equal to or greater than 10% of the maximum shell capacity of the tank car; and

(j) the certificate number "SR 11328" is stenciled on each long side of the tank car in letters and numbers no less than 100 mm (4 in.) high.

Note: The issuance of this Equivalency Certificate in no way reduces the certificate holder's responsibility to comply with any other requirements of the Transportation of Dangerous Goods Regulations, the Technical Instructions for the Safe Transportation of Dangerous Goods by Air, the International Maritime Dangerous Goods Code, and the Canadian Aviation Regulationsnot specifically addressed in this certificate.

Explanatory Note

This Equivalency Certificate authorizes the transportation of anhydrous hydrogen fluoride in 112S500I pressure tank cars equipped with a PRV that does meet the minimum flow requirement of Appendix A of the AAR M-1002 as required by clauses 8.2.6.1 and 10.3.3 of Transport Canada standard TP14877E, "Containers for the Transport of Dangerous Goods by Rail", December 2013. However, an equivalent level of safety to the performance standard of the thermal protection system is met by a combination of much increased thickness (35 mm) of the shell and heads and increased outage (10%). It is not desirable to meet the performance standard with a traditional system of jacket and insulation for hydrogen fluoride tank cars as the exterior of the car must be inspected for defects (hydrogen blisters) on a regular basis.

Also, the cars meet the toxicity by inhalation hazard dangerous goods additional requirements for tank-head puncture-resistance and top fittings protection. As such the pressure car maximum gross mass of 119 300 kg (263 000 lb.) is raised to 130 000 kg (286 000 lb.) to allow for the application of additional thickness of shell and heads, head-shields and top-fitting protection.
