ISO Certification can be a useful and effective tool to add credibility, by demonstrating that your product or service meets the expectations of your customers and regulatory guidelines. International Standards make things work and they give world-class specifications for products, services and systems, to ensure quality, safety and efficiency and they are also instrumental in facilitating international trade. In simple, we can describe that an International Standard is a document or certificate containing practical information and best practice. It often describes an agreed way of doing something or a solution to a global problem.
