3、n or networking permitted without license from IHS-,-,-The CANADIAN GENERAL STANDARDS BOARD (CGSB), under whose auspices this National Standard of Canada has been developed is a government agency within Public Works and Government Services Canada. CGSB is engaged in the production of voluntary stand
4、ards in a wide range of subject areas through the media of standards committees and the consensus process. The standards committees are composed of representatives of relevant interests including producers, consumers and other users, retailers, governments, educational institutions, technical, profe
5、ssional and trade societies, and research and testing organizations. Any given standard is developed on the consensus of views expressed by such representatives. CGSB has been accredited by the Standards Council of Canada as a national standards-development organization. The standards that it develo
6、ps and offers as National Standards of Canada conform to the criteria and procedures established for this purpose by the Standards Council of Canada. In addition to standards it publishes as national standards, CGSB produces standards to meet particular needs, in response to requests from a variety
7、of sources in both the public and private sectors. Both CGSB standards and CGSB national standards are developed in conformance with the policies described in the CGSB Policy Manual for the Development and Review of Standards. CGSB standards are subject to review and revision to ensure that they kee
8、p abreast of technological progress. Suggestions for their improvement, which are always welcome, should be brought to the notice of the standards committees concerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards. An up-to-date listing of CGSB
9、standards, including details on latest issues and amendments, and ordering instructions, is found in the CGSB Catalogue, which is published annually and is available without charge upon request. An electronic version, CAT, is also available. More information is available about CGSB products and serv
10、ices at our Web site www.ongc-cgsb.gc.ca. Although the intended primary application of this standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. The testing and evaluation of a
11、product against this standard may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish
12、 appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. CGSB neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed. Attention is drawn to the possibilit
13、y that some of the elements of this Canadian standard may be the subject of patent rights. CGSB shall not be held responsible for identifying any or all such patent rights. Users of this standard are expressly advised that determination of the validity of any such patent rights are entirely their ow
14、n responsibility. Further information on CGSB and its services and standards may be obtained from: The Manager Strategic Standardization Division Canadian General Standards Board Gatineau, Canada K1A 1G6 The STANDARDS COUNCIL OF CANADA is the coordinating body of the National Standards System, a coa
15、lition of independent, autonomous organizations working towards the further development and improvement of voluntary standardization in the national interest. The principal objects of the SCC are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting
16、 the health, safety and welfare of the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international cooperation in the field of standards. A National Standard of Canada (NSC) is a standard prepared or reviewed by an accredited Standards D
17、evelopment Organization (SDO) and approved by the SCC according to the requirements of CAN-P-2. Approval does not refer to the technical content of the standard; this remains the continuing responsibility of the SDO. A NSC reflects a consensus of a number of capable individuals whose collective inte
18、rests provide, to the greatest practicable extent, a balance of representation of general interests, producers, regulators, users (including consumers), and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard, which is capable of making a significa
19、nt and timely contribution to the national interest. Those who have a need to apply standards are encouraged to use NSCs. These standards are subject to periodic review. Users of NSCs are cautioned to obtain the latest edition from the SDO, which publishes the standard. The responsibility for approv
20、ing standards as National Standards of Canada rests with the: Standards Council of Canada 200-270 Albert Street Ottawa, Ontario K1P 6N7 How to order Publications: by telephone 819-956-0425 or 1-800-665-2472 by fax 819-956-5740 by mail CGSB Sales Centre Gatineau, Canada K1A 1G6 in person Place du Por

41、1WARNINGThis standard calls for the use of substances and/or procedures that may be injurious to healthif adequate precautions are not taken. It refers only to technical suitability and does notabsolve the user from legal obligations relating to health and safety at any stage. It has beenassumed in
42、the drafting of this standard that the execution of its provisions is entrusted toappropriately qualified and experienced people.1 ScopeThis Part of ISO 14184 specifies a method for determining the amount of free formaldehydeand formaldehyde extracted partly through hydrolysis by means of a water ex
43、traction method.The method can be applied to the testing of textile samples in any form.The procedure is intended for use in the range of free and hydrolysed formaldehyde on thefabric between 20 mg/kg and 3500 mg/kg when determined by this method. The lower limitis 20 mg/kg. Below this limit the res
44、ult is reported as not detectable.A method for determination of released formaldehyde is given in ISO 14184-2.2 Normative referencesThe following standards contain provisions which, through reference in this text, constituteprovisions of this Part of ISO 14184. At the time of publication, the editio
45、ns indicated werevalid.
