ISO9001-2008 (GB/T19001-2008) quality management system certification

江西体彩11选5多乐彩走势图今天 www.phcnlx.com.cn Since founded in 2007, our company regard "respect for the customer, service first, scientific and technological innovation, meet demand" as our quality policy. First of all, company dedicated to promoting the internal management of systematic organization; secondly, company gradually establish a quality management system in accordance with ISO 9000 standards. In 2010, the establish quality management system passed ISO9001-2008(GB/T19001-2008) certification of the quality management system for the first time. Certification scope: biological reagents (proteins, antibodies) R&D and production

In accordance with the requirements of ISO9001-2008 quality management system, company developed quality management system documents, such as quality manuals, procedures, quality plans / SOPs and quality records, Quality activities have been carried out in order. Employees follow laws, reducing blindness of quality management system can be divided into four levels, including safety, management, equipment, quality control and research and development production, up to 536 SOP.

Company established a tripartite review mechanism of periodic audit: the first parth (internal audit), the second party (customer review), a third party (external audit) to assess the suitability, adequacy, effextiveness and effciency of the company's quality management system.
