CSA standards reflect a national consensus of produc- ers and users - including manufacturers, consumers, retailers, unions and professional organizations, and go

The standards are used widely by industry and commerce and often adopted by mu- nicipal, provincial, and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associatio

12、, as may be appropriate to the subject in hand. It normally is a standard which is capable of making a significant and timely contribution to the national interest. Approval of a standard as a National Standard of Canada indicates that a standard conforms to the cri- teria and procedures established
13、 by the Standards Council of Canada. Approval does not refer to the technical content of the standard; this remains the continuing responsibility of the accredited standards- development organization. Those who have a need to apply standards are encour- aged to use National Standards of Canada whene

The ever increasing use of all types of trailers, particularly the recreational vehicle type, at high speeds demands that running gear be of good quality and that i

It will also assist authorities having jurisdiction in the preparation of suitable safety legislation. has been made for the use of “

The performance requirements for this type of running gear are not as stringent as those for the reusable ty
35、pe. This Standard is not intended for trailers that will be used predominantly for agricultural purposes, nor for the heavy commercial trailers. In regard to the latter, it was determined that the most convenient way to express this limitation in the Standard was to exclude trailers with full air-br

41、 Trailer Running Gear October, 1985 7 Foreword Foreword Certification organizations, as accredited by the Standards Council of Canada, have their own criteria and procedures for certification services. The following paragraphs define CSA Certification policies. The Canadian Standards Association pro
42、vides certification services for manufacturers who, under license from CSA, wish to use the appropriate registered CSA Marks on certain products of their manufacture to indicate conformity with CSA Standards. CSA Certification for a number of products is provided in the interest of maintaining agree
43、d-upon standards of quality, performance, interchangeability and/or safety, as appropriate. Where applicable, certification may form the basis for acceptance by inspection authorities responsible for enforcement of regulations. Where feasible, programs will be developed for additional products for w
44、hich certification is desired by producers, consumers or other interests. In performing its functions in accordance with its objectives, CSA does not assume or undertake to discharge any responsibility of the manufacturer or any other party. The opinions and findings of the Association represent its
45、 professional judgement given with due consideration to the necessary limitations of practical operation and state of the art at the time the Standard is processed. Products in substantial accord with this Standard but which exhibit a minor difference or a new feature may be deemed to meet the Stand
46、ard providing the feature or difference is found acceptable utilizing appropriate CSA Certification Division Operating Procedures. Products which comply with this Standard shall not be certified if they are found to have additional features which are inconsistent with the intent of this Standard. Pr
47、oducts shall not be certifiable if they are discovered to contravene applicable Federal laws or regulations. Testing techniques, test procedures and instrumentation frequently must be prescribed by the CSA Certification Division in addition to the technical requirements contained in Standards of CSA
48、. In addition to markings specified in the Standard the CSA Certification and Testing Division may require special cautions, markings and instructions that are not specified by the Standard. Some tests required by CSA Standards may be inherently hazardous. The Association neither assumes nor accepts
49、 any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed, whether performed in whole or in part by the manufacturer or the Association, and whether or not any equipment, facility or personnel for or in connection with the test is furnished by the manufacturer or the Association.
