Abstract

Regulations and Standards are necessary for developing products that are “safe to use”, whether the product is a building, an aircraft, or a pressure vessel. The National Physical Laboratory (NPL) makes a significant contribution to standards and regulations. For example, In the field of polymer composites/fibre reinforced plastics NPL’s work has contributed to 17 standards in the last two decades. To measure the effect of regulations and standards on the economy, we used the aerospace industry as a use case. The aerospace industry has an organisation, the European Aviation Safety Agency (EASA), dedicated to providing codified standards and guidelines for companies operating in the sectors. The standards cover aspects of aviation from unmanned aircraft systems to the use of composite materials. Furthermore, the EASA makes this information available in an open-source database. Using a methodology called Event Study, stock market data and the EASA's open-source database, we calculated the effect of 64 proposed amendments and published amendments by the EASA for large aircraft (called CS-25) on the stock prices of companies that supply parts made from composite materials to the aerospace sector.
