It is important that the edges of the Bars must not be sharp, so to avoid the risk of injury during handling. Proper stacking and handling of a Bar will be taken into consideration during Bar inspections. Refiners must ensure that their Bars will stack safely when considering the dimensions of their proposed Bars. R Bars must be ingot-shaped (i.e., having a trapezoidal cross-section, both along the length and across the width of the Bar) with sufficient undercut to facilitate handling but without resulting in the width of the bottom surface being so narrow that the Bar cannot be safely stacked. The Refiner must pay for LBMA’s costs in the examination and testing of the Bars. Once the Bar inspection is complete, the Bars may then be sent to the Referees for further analysis to ensure that the Bars meet the specifications in these Rules. LBMA may then request that two Bars cast using the proposed alternative method must be sent to London for visual inspection. G Any Refiners wishing to convert to the use of the above-mentioned non-conventional methods of Bar production must submit a proposal to LBMA for consideration prior to implementation. non-conventional method of melting grain in an induction tunnel system, or in the case of silver, by continuous casting.īars cast in open moulds should be produced at a single pouring.conventional method of pouring molten metal into them or.R Bars must be produced in graphite or cast iron moulds, either by the: R Bars must be weighed as provided for in Annex B, and in accordance with the procedure set out in Annex C. 2.1 General Description of Good Delivery Bars 2.1.1 Weighing
