Service Introduction

Given that the rapid development of China's rail transit industry, a variety of new materials are widely used in rail vehicles, particularly, it is important to control the quality of materials from the source. We should not only test various performance indexes according to product standards and customer's technical requirements, ensure the quality superiority of material grade, and do well in type test and daily monitoring; but also to provide various data support in the development stage of new products, so as to design and screen out the optimal formula and release more competitive new products. More perfect quality assurance measures will be established for the main engine factories and suppliers at all levels through the control of raw materials.

Product Scope:

Most rail transit components and materials, such as FRP, honeycomb panel, rubber, plastic, adhesive, coating, fabric leather, metal, etc.

Relevant Qualifications:

CNAS, CMA and relevant automobile manufacturers reorganization
