Acceptable results Clause Samples

Acceptable results. The cylinder shall be hydraulically tested to destruction in accordance with the procedure in paragraph A.12. The burst pressure of the cylinder shall be not less than 85 per cent of the minimum design burst pressure." Through the whole text of the Regulation, replace the references to "acid environmental test" by "environment test" and delete the references to Annex 3A, Appendix H. Paragraph A.16., amend to read: "A.16. Penetration tests A cylinder pressurised to 20 MPa ± 1 MPa with compressed gas shall be penetrated by an armour piercing bullet with a diameter of 7.62 mm or greater. The bullet shall completely penetrate at least one side wall of the cylinder. For type CNG-1 designs, the projectile shall impact the side wall at 90°. For type CNG-2, CNG-3 and CNG-4 designs, the projectile shall impact the side wall at an approximate angle of 45°. The cylinder shall reveal no evidence of fragmentation failure. Loss of small pieces of material, each not weighing more than 45 grams, shall not constitute failure of the test. The approximate size of entrance and exit openings and their locations shall be recorded." Paragraph A.22., amend to read:

Acceptable results. The container shall vent through a pressure relief device, and no burst shall occur.
