* BS EN 14385 specifies the use of 25% nitric acid for rinsing glassware on site. In the UK 5% nitric is commonly used. The STA are currently seeking  clarification from the CEN working group responsible for the standard. In the meantime the Environment Agency will continue to accept the use of 5% nitric acid.
