    在中国，弹簧的制造历史源远流长，在中国较早的弹簧如农民使用的“扁担”，其历史远在工业诞生之前。发展至今全国已有螺旋弹簧制造企业500余家，钢板弹簧制造企业300余家，气弹簧制造企业100余家，其他弹性元件制造企业100余家，总计弹簧及弹性元件制造企业达1000余家，年弹簧产品总产值已过数十亿元。汽车用发动机气门弹簧、油泵弹簧，减震系统用悬架弹簧、钢板弹簧在弹簧产品总产值的比重很大，其产品不仅提供国内汽车厂商、配套市场，而且出口量逐年上升。随着中国市场经济的快速发展，电器产品的国内消费量和出口量剧增，因而小弹簧的产值和产量增长较快。气弹簧产品是80年代初随着引进技术，而在我国应运而生的新产品，近10年的发展速度相当迅速，出口国和出口量都连年递增。中国的弹簧标准化工作始于60年代初期，至今已40多年，已经形成了较为完善的弹簧标准体系，目前已具有弹簧国家标准22项、行业标准20项。1999年由国家批准成立全国弹簧标准化技术委员会，全面推进弹簧标准化工作。
    中国是发展中国家，是弹簧产品的制造大国，良好的经济环境和政策吸引着许多外资企业到中国来发展，标委会将全面跟踪世界范围弹簧标准的最新变化，及时为弹簧行业服务，以提高我国弹簧产品的竞争力，适应全球采购的需要。

    Spring production has a long story in China, and the earlier spring made in China behaved just like the “shoulder-pole” used by peasants. The spring came into being before the birth of the Industry. There are up till now approximately 1,000 enterprises specialized in the production of spring and elastic elements with the gross output value of about several billion RMB, including more than 500 manufacturers for coil spring, more than 300 for plate spring, more than 100 for gas spring and about 100 for other elastic elements. The proportion of the valve spring and oil pump spring for automobile engines and the bearing spring and plate spring for shock isolation system in gross output value of spring products is very large. The products are not only provided for the domestic automobile manufacturers and supporting market but also exported to other countries with increasing volume year by year. With the rapid development of market economy in China and the explosion of domestic consumption and export volume, the production value and output of small springs enjoy a smooth increase. The gas spring is a kind of new products emerging as the times require with the introduction of advanced technology in 1980s, and have made a rapid progress in recent ten years with the annual increase of the exporting countries and export volume. Spring standardization in China began from early 60s, more than 40 years up to now, and it has developed a more sophisticated system, with 22 national standards and 20 industry standards. The National Spring Standard Technology Association (NSSTA) was established to promote the comprehensive spring standardization in 1999 after the approval from the country.

    China is one of the developing countries in the world, but also one of main countries for spring products. Good economic environment and policies attract many foreign enterprises to development their businesses in China. The National Spring Standard Technology Association will make a close tracking to the latest changes of the spring standard in the world, and provide timely services for the spring Industry to improve the competitiveness of the spring products of our country and meet the demand of the global procurement.
