The test was “harmonized” in 2009 and as such particular aspects of the procedure had been transformed to support a worldwide testing requirement. Prior to 2009, there have been versions of the test in several nations which required re-testing every time a provided solution was bought in a country different with the country which the products was originally tested in. This standardization has mainly enhanced the do the job move of products in a global industry, and built it less difficult for laboratory experts in different international locations to take care of compliance concerns whenever they crop up
