11 Testing 11.1 Prior to conducting tests listed in this section, careful inspection shall be made for visible damage and faulty welding. After joint welding of blankets in pipelines and structures, all welds shall be subjected to the tests specified in this section. 11.2 Particular attention must be given to weld beads on both sides of weld strips (see illustration). After welding, beads should be visible on both sides of the weld strip. The weld must be checked by probing the fillet area with a well worn (i.e. no sharp edges) screwdriver blade. At any place where the probe indicates a weak weld, or enters more than 3mm, a reweld shall be made in accordance with the procedure specified in Clauses 12.6 and 12.7 of this specification. If overheating has occurred during welding the evidence is charring at the edge of the strip. All charred sections must be replaced. 11.3 If required by the client, the lined surface shall be 100% spark tested using an approved spark tester and brush with a potential of at least 10,000 volts. Two alternative methods of positively testing joints and patches are the vacuum box method for flat areas such as tanks, and the pipe weld tester for pipelines. Both the vacuum box and pipe weld tester must be of an approved design. If the vacuum box is used as a means of testing, <strong>Humes</strong> should be consulted as special design characteristics assist in testing by this method. Defective areas found by these tests must be repaired as per Section 12 and subsequently retested. 11.4 Where required by the client, a pull test can be performed to check that proper embedment of keys has been achieved. A direct pull is applied normal to the concrete surface, on a cut section of the embedded sheet containing a single embedded key 100mm to 200mm long. The concrete should be fully cured and the key shall withstand the specified pull of 14 N/mm without rupture of the concrete or the key, or withdrawal of the key from the concrete. Strictly the test should be made at a temperature between 10 O C and 27 O C and at least 14 days after embedment. Refer to <strong>Humes</strong> if full details are required. 11.5 Where large areas of lining are involved, testing must be carried out progressively as the work proceeds to avoid accumulation of defects from faulty workmanship which could have been detected and corrected at an early stage. Spark testing may not detect faults in welds or where sheets overlap, and must be supplemented by the other procedures described above in order to ensure sound workmanship in these areas.
