Commodity is a ubiquitous gadgets, some common simple goods, we can draw experience, namely the price, brand, handle and so on way to evaluate its quality. For some very professional products, such as miniature dc motor controller, unless we infiltration in this field for many years, otherwise it is difficult to judge. In this case, some professional certification is produced. Common have 3 c, CE, rohs, ul and so on, I believe you already familiar. Today we will introduce to you two kinds of less common certification.
the ISO/TS16949: full name is & other; The quality management system & ndash; The auto industry in the production of parts and related services to organize the implementation of ISO9001:2000 special requirements & throughout; 。 ISO/TS16949 standard targeted and applicability is very clear, only applies to automotive oems and its direct spare parts manufacturer, that is to say, the manufacturer must be directly related to production of car, can carry out processing and manufacturing activities, and through this activity enables products value-added. At the same time, for the qualification certification company factory also has the strict limit, only those who have support function units, such as design centres, corporate headquarters and distribution center, etc. , or those to the vehicle manufacturer or the manufacturer of auto spare parts manufacturers manufacturing equipment and tools, cannot be certified. Motor controller as a professional manufacturer of brushless dc motor controller, has applied for a certification, currently in the review, is expected this year could get the certificate.
NEMA: National Electrical Manufactures Association the National Electrical manufacturers Association. NEMA to affect the safety of electrical equipment standards. Level is as follows: NEMA1 universal (Indoor)NEMA2 drip-proof type (Indoor) NEMA3 rainproof, dustproof, (Outdoor)NEMA4 rainproof, dustproof,Indoor/outdoor) NEMA4X rainproof, dustproof, anti-corrosion,Indoor/outdoor)NEMA6 underwater, dustproof, waterproof,Indoor/outdoor) NEMA7 explosion protection district 1 NEMA8 district 1 NEMA9 explosion-proof area NEMA10 mine 2 NEMA11 anticorrosive, drip-proof (Indoor)NEMA12 industrial anti-corrosion, drip-proof (Indoor) NEMA13 prevent oil, dustproof,Indoor)NEMA13R rain, sleet (Outdoor)
this certification is not very common, in general, people still like to use to represent the dust-proof waterproof IP level.
if you have more interesting certification, welcome to share. QQ: 2586674401。
