UL Certification

English Underwriters Laboratories UL (Underwriter Laboratories Inc.) Shorthand .
UL safety test of America’s most authoritative , but also in security testing and identification of the boundaries of large private institutions . It is an independent , non-profit , do testing for public safety professional organizations . It uses scientific methods to study the test to determine the extent of a variety of materials , devices, products , equipment, and construction of life , property damage and whether hazards ; determine , write, issue the appropriate standards and help reduce and prevent life property losses of data , while carrying out the facts research business .
In short , it is primarily engaged in operating and safety certification and product safety certification business, the ultimate goal is to get the product to the market with considerable safety standards , guaranteed to make personal contributions to health and property safety . Product safety certification as an effective means to eliminate technical barriers to international trade , UL, to promote the development of international trade also played an active role.

UL was founded in 1894 , the initial phase of the action in maintaining UL main fire financed by the insurance sector , until 1916 , UL was completely independent. After nearly a century of development , UL has become a world -known certification body , has its own set of strict management system of the organization , standards development and product certification programs. UL by a Council to manage security experts, government officials , consumers , education , utilities , insurance and standards department composed of representatives of the daily work of the president, vice president handling . Currently , UL has five laboratories in the United States , headquartered in Northbrook town north of Chicago , and set up a corresponding laboratory in Taiwan and Hong Kong , the United States, is a symbol for consumers UL safety mark . Global , UL is one of the most trusted manufacturers conformity assessment providers.

ASTM Certification

ASTM predecessor of the International Society for Testing Materials (International Association for Testing Materials, IATM).
1880s , to address the comments and disagreements buyers and suppliers in the purchase and sale of industrial processes to produce the material , it was proposed to establish technical committee system , the Technical Committee composed of representatives of all aspects of the organization to participate in technical seminars , discussions to resolve the material specification , test procedures and other aspects of contentious issues .
ASTM is one of America’s oldest and largest nonprofit academic standards bodies . After a century of development , ASTM existing 33,669 ( individual and group ) members , of which there are 22,396 members of the main committee as a technical expert working in its various committees. ASTM technical committees under total of 2004 Technical Sub-Committee . There are 105,817 units participated in the ASTM standards development work , the main task is to develop the characteristics and performance standards , test methods and procedures standard materials, products , systems, and services sectors and promote the development and promotion of knowledge .

1 ASTM standard classification

ASTM standards of the following six types.
( 1 ) Standard Test Method (Standard Test Method) it is for the identification, detection and evaluation of material , product, system or service quality , characteristics and parameters and other indicators and the use of prescribed procedures .
( 2 ) Standard Specification (Standard Specification) of its materials, products , systems, or project technical requirements and gives specific instructions , but also to meet the technical requirements of the proposed procedure should be used .
( 3 ) Standard Practice (Standard Practice) it has one or more particular description given operation or function , the process does not produce results .
( 4 ) Standard Terminology (Standard Terminology) describe or define its terms , symbols , abbreviations, Acronyms explained.
( 5 ) Standard Guide (Standard Guide) it has a series of selection or usage is explained , but does not describe the specific implementation methods.
( 6 ) standard classification (Class.fication) it according to their origin , composition, performance, or use of materials, products, systems, or to distinguish and classify specific services

FCC Certification

FCC is FEDERAL COMMUNICATIONCOMMISSION ( Federal Communications Commission ) for short. FCC certification is on electromagnetic compatibility testing and certification , the U.S. FCC operating frequency for electromagnetic interference 9KHZ more electronic products are generated by the control . Electrical and electronic products sold in the United States , the need to apply for FCC certification and labeling FCC label .
FCC Certification There are three main ways :

Mainly for products
Self- verification
