					Uncertainty
					
						The certified value(s) and uncertainty(ies) are determined in accordance with ISO 17034
						with an 95% confidence
						level(k=2). Uncertainty is based on the Total Combined Uncertainty, including uncertainties of characterisation,
						homogeneity and stability testing. Stability values are based on real evidence opposed to simulation.
					
				 
				
					Traceability
					
						The balances used for gravimetric measurements are calibrated with weights traceable to the national standards.
						The calibration of the balances is verified annually by an external accredited calibration service. This analysis
						method has been verified using an approach consistent with ISO 17034:2016 & ISO
								17025:2017.

				Intended Use
				
					This RM is intended for use in a laboratory as a calibration and quality control standard or in method development
					for analytical techniques.
				
			 
			
				Storage
				
					This reference material meets the specification stated in this certificate until the expiry date, provided it is
					stored unopened at the recommended temperature here in. If storage after opening is necessary, the RM should be
					tightly closed and kept from light and moisture.
				
			 
			
				Hazards
				
					Read Material Safety Data Sheet (MSDS) and understand any potential hazard(s) prior to the use of this product.
					All chemicals should be considered potentially hazardous in nature and should only be handled by qualified
					personnel using established good laboratory practices.
				
			 
			
				Homogeneity
				
					Random replicate samples of the final packaged RM have been analysed to prove homogeneity compliant with ISO
							17034.
				
			 
			
				Instructions for use
				
					It is recommended to use 1 mg as the minimum sample size and if less material is used, to increase the certified
					uncertainty by a factor of two for half sample and four for a quarter of sample.Visit the support section of our
					website technology videos and frequently asked questions.
