2.2.3 Equipment Monitoring and Calibration All equipment is to be routinely monitored, calibrated and checked as relevant, to ensure correct operation as outlined in the company Sampling Manual or the Operating Procedures. The frequency of calibration and these checks will vary based on the type of equipment, frequency of use and operating procedures of the company. At a minimum, equipment should be checked annually. During periods of continual use, equipment should be checked more frequently. Checking of all equipment including any calibration must be done by a person appropriately qualified to carry out such a task. Personnel may be external to the company or internal staff skilled in that task. Records must be kept of all such maintenance and checks. If equipment is found to not be properly calibrated, the Sampling Manual or Operating Procedures is to be checked for actions to be taken - with corrective action to be taken as soon as practically possible. Refer to the appropriate TGD for specific details by equipment type.5 2.2.4 Trade Certification of Equipment Where equipment is used that falls under National Measurement Institute (NMI) regulations and is considered to be “for trade”, it must meet conditions as outlined by the NMI6. This includes any equipment that is referenced in those regulations such as for grain quality assessment, weighbridges and analytical balances used at any stage throughout the supply chain such as at receival. Industry is committed to the use of all equipment of a standard for “use in trade” where the outcome of the grain classification process is a payment to the supplier of the grain. All other equipment used for testing grain that does not fall under this NMI legislation is also to be checked under similar processes, as it is the desire of industry to ensure all equipment used for grain testing is suited to that purpose. 2.3 Storage Facilities 2.3.1 Storage Construction & Maintenance Grain storage facilities: • Are to be soundly constructed; • Must be maintained to minimise the entry of pests, vermin and moisture that may affect stored grain; • Must prevent seepage of grain from the storage; and • Are to be located in an area, and the surrounds are to be of suitable construction material, to minimise contamination of grain and to prevent damage to stored grain through water ingress. Where an individual storage is categorised as sealed, and is used on that basis, it is to comply with the Australian Standard AS26287. This includes the requirement to comply with the pressure test as outlined in that Standard. Storages should be suitable for the commodity to be stored.
