Developing countries other barriers

Comparable quality of test data forms the basis for the mutual acceptance of data among countries. If individual countries can confidently rely on test data developed in other countries, duplicative testing can be avoided, thereby saving time and resources. The application of these principles should help to avoid the creation of technical barriers to trade, and further improve the protection of human health and the environment. GLP principles are explicitly presented below. 

Although law implementation is regarded as the major barrier and driver for EDPs in developing countries, comparable performance and cost of EDPs with conventional plastics are other main factors for the wide acceptance of EDPs. 

Nevertheless, it is important to point out that the laboratories where the different validation methods are carried out should be certified in the execution of the good laboratory practice (GLP). These principles of GLP are a group of rules, procedures and estabUshed practices and are developed by the OECD (Organisation for Economic Cooperation and Development). This normative has been assumed by the EU in the directives 87/18/CEE and 99/11/CE ""The purpose of these principles of good laboratory practice (GLP) is to promote the development of quality test data. Comparable quality of test data forms the basis for the mutual acceptance of data among countries.
