Foreword This ETSI Guide (EG) has been produced by ETSI Technical Committee Methods for Testing and Specification (MTS). Introduct
22、ion ETSI produces technical standards for a wide range of communication applications. All these standards need to be thoroughly validated and many different methods are available for this purpose. The present document collects and presents those validation methods which are practical and have been s
23、uccessfully applied either within ETSI or in other standardization bodies. Each method has its advantages and disadvantages and they are probably most effective if used in combination and at all stages of the standards development process. A three level approach for the basic, strong and rigorous va
24、lidation of standards is presented to guide the selection and application of standard validation methods. ETSI ETSI EG 201 015 V2.1.1 (2012-02)61 Scope The present document identifies and describes a number of practical methods that can be used to validate all types of standards produced by ETSI. Th
25、e methods described are as follows: review methods; model-based methods; product-based methods; and testing. It also gives guidance on how and when each of these methods can be used most effectively within ETSIs standards engineering process. 2 References References are either specific (identified b

49、s ETSI ETSI EG 201 015 V2.1.1 (2012-02)94 Validation overview Any standard is a collection of requirements which, if implemented correctly, achieve certain objectives in a product. These requirements could specify physical characteristics such as length, voltage and accessibility or behaviour such as the interchange of messages and the responses to particular stimuli. The purpose of validation is to ensure as far as possible that the requirements expressed in the standard do, in fact, meet
