What is BS IEC 62899‑302‑2-Accurate inkjet droplet volume about?  
BS IEC 62899 is an international standard that discusses printed electronics.
BS IEC 62899‑302‑2 is the 302th part in the multi-series that specifies the method for determining accurate inkjet droplet volume based on images obtained by drop-in-flight measurement systems. Accurate measurement of jetted droplet volume is an important issue in printed electronics applications because the amount of material deposited on the substrate is directly related to device performance.
Note: BS IEC 62899‑302‑2 does not apply to imaging systems using interference fringes, such as holography or phase doppler anemometry.
Note: BS IEC 62899‑302‑2 is not limited to drop-on-demand inkjet systems, but might not be applicable to continuous inkjet or liquid dispensing systems.
Who is BS IEC 62899‑302‑2- Accurate inkjet droplet volume for? 
 BS IEC 62899‑302‑2 on inkjets is relevant to:
- Printed electronics industry
- Manufacturers of printed electronics and inkjets
- Semiconductor industry
- Electronic engineering industry
- Product design engineers
Why should you use BS IEC 62899‑302‑2- Accurate inkjet droplet volume?  
Drop volume is the amount of jetted fluid from an inkjet print-head nozzle measured by single event imaging. Precise and accurate drop placement and drop volumes is what makes inkjet printing suitable for electronics, displays, PCBs and optics, amongst other things. Drop direction influences the achievable spatial resolution of the printed material and thus, affects the performance of printed electronics products. 
BS IEC 62899‑302‑2 concerns the accurate determination of inkjet droplet volume from high-speed flash images of inkjet droplets traveling in-flight from inkjet print-head nozzles.
Overall, BS IEC 62899‑302‑2-compliant measurement methods can significantly increase drop landing accuracy, allowing for higher resolution displays.
