CGSB is engaged in th
3、e production of voluntary standards 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
4、 institutions, technical, professional and trade societies, and research and testing organizations. Any given standard is developed on the consensus of views expressed by such representatives. The Ministers Advisory Council on CGSB reviews the results of the consensus process. CGSB has been accredit
5、ed by the Standards Council of Canada as a national standards-writing organization. The standards that it develops 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
6、as national standards, CGSB produces standards to meet particular needs, in response to requests from a variety of sources in both the public and private sectors. Both CGSB standards and national standards developed by CGSB are developed in conformance with the policies described in the Policy Manua
7、l for the Development and Maintenance of Standards by CGSB. CGSB standards are subject to review and revision at any time, so as to ensure that they keep abreast of technological progress. Suggestions for their improvement, which are always welcome, should be brought to the notice of the standards c
8、ommittees concerned. Changes to standards are issued either as separate amendment sheets or in new editions of standards. An up-to-date listing of CGSB standards, including details on latest issues and amendments, and ordering instructions, will be found in the CGSB Catalogue, which is published ann
9、ually and is available without charge upon request. 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. Many tests required by
10、 CGSB standards are inherently hazardous. CGSB neither assumes nor accepts any responsibility for any injury or damage that may occur during or as the result of tests, wherever performed. CCSB takes no position respecting the validity of any patent rights asserted with any item connected with this s
11、tandard. Users of this standard are expressly advised that determination of the validity of any such patent rights are -entirely their own responsibility.

12、rds Board Ottawa, Canada KIA 1G6 The STANDARDS COUNCIL OF CANADA is the co-ordinating body of the National Standards System, a federation of independent, autonomous organizations working towards the further development and improvement of voluntary standardization in the national interest. The princi
13、pal objectives of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety and welfare of the public, assisting and protecting the consumer, facilitating domestic and international trade, and furthering international
14、co-operation in the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which reflects a reasonable agreement among the views of a number of capable individuals whose collective interests provide, to the greatest practica
15、ble extent, a balance of representation of producers, users, consumers and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard that is capable of making a significant and timely contribution to the national interest. Approval of a standard as a Nat
16、ional Standard of Canada indicates that a standard conforms to the criteria and procedures established 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-writing organization. Th
17、ose who have a need to apply standards are encouraged to use National Standards of Canada whenever practicable. These standards are subject to periodic review; therefore, users are cautioned to obtain the latest edition from the organization preparing the standard. The responsibility for approving N

SCOPE 1.1 T
28、his standard applies to unpigmented sealer intended primarily for use on interior resilient and nonresilient floors other than those of wood or cork. 1.2 Sealers manufactured to this standard are intended for use in sealing resilient and nonresilient surfaces. These sealers may be used prior to the
29、application of maintenance finishes or as stand-alone sealer finishes. Type 1 solvent-based sealer should be used only on nonresilient surfaces such as concrete, terrazzo, marble, magnesite, ceramic and slate. Type 2 water-based sealer may be used on resilient surfaces such as asphalt, linoleum, vin
30、yl, vinyl composites, rubber and mastic, or on nonresilient surfaces as recommended by the manufacturer. Type 2 water-based sealer is the recommended choice in fire-hazard areas such as furnace rooms and where there is an open flame, and in hospital and food-processing areas where solvent fumes are
31、not permitted. The testing and evaluation of a 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 consu
32、lt the appropriate authorities and to establish appropriate health and safety practices in conjunction with any existing applicable regulatory requirements prior to its use. 1.3 2.
