一、制定标准的意义液氮生物容器是开展家畜冷冻精液配种新技术和低温医学研究及生物工程、科研生产中的必不可少的专用设备。我国自74年开始研制液氮生物容器,77年小批量生产,在短短的几年内先后有20多个科研单位和工厂进行了研制和生产,使产品质量不断提高,并迅速发展为年产上万只容器的新行业。目前该产品不仅能够基本满足国内需要、改变了在82年前主要依靠进口的局面,而且已开始有少量出口。过去由于全国七个主要生产厂分布在五个部、五个省,涉及的部门较多,行业标准化工作一直没有开展。至今除四川、河南有省标,航空工业部有10升容器部标之外(机械工业部标准正在制定),全国还没有统一的国家专业标准,个别厂家甚至没有企业标准。造成产品名
First, the development of a standard significance Liquid nitrogen biological container is carried out in livestock breeding frozen semen new technology and cryogenic medical research and biological engineering, research and production of essential special equipment. Since 74 years, our country has been developing liquid nitrogen biological containers and has been producing in small quantities for 77 years. Over the past few years, more than 20 research institutes and factories have successively developed and produced such products to continuously improve their product quality and rapidly develop into an annual output Thousands of new container industry. At present, the product can not only basically meet the domestic needs, changed the situation that mainly relied on imports 82 years ago, and has begun to have a small amount of exports. In the past, as the seven major manufacturing plants in the country were distributed in five ministries and five provinces, involving more departments, the standardization of the industry has not been carried out. So far in addition to Sichuan, Henan provincial standard, the Ministry of Aeronautical Industry has 10 liters container department outside the standard (Ministry of Machinery Industry standards are being developed), the country does not have a unified national professional standards, individual manufacturers do not even have business standards.
