1.0.4 The construction of railway signal engineering shall implement the sustainable development strategy of national economy, properly fulfill such works as environmental protection and water & soil conservation, rationally utilize the resources and accomplish civilized and safe construction.
1.0.5 The quality data acquired in the inspection and testing on the constructional quality of railway signal engineering shall be true and reliable and comprehensively reflect the condition of engineering quality, and the methods and instruments adopted shall be in accordance with those specified in the relevant standards.
1.0.6 The constructional quality requirements in contract agreement document and engineering technical documents adopted in railway signal engineering construction shall not be lower than those in this standard.
1.0.7 The constructional quality acceptance of railway signal engineering shall meet the requirements stipulated in this standard and those in relevant current national standards.
