Changes in construction techniques that require joints between structural elements to be sealed in order to prevent the penetration of air, moisture and dust into the joint resulted in the use of materials that have not always produced satisfactory results. Throughout the world various standards writing organizations over the past twenty years have attempted to resolve the problem by developing materials and performance standards for jolnt sealing products . The international exchange of technology and materials is such that international standards for these materials based upon internationally accepted test procedures is essential in order to avoid establishing technical barriers to trade. The paper describes the activities of the International Standards Organization in the field of joint sealing compounds, the contributions of North American technology to this activity and the potential input of the 1979 GATT agreement upon the needs for international standards for joint sealing compounds. Particular emphasis will be placed in the paper on how Canada develops its National Standards for Joint Sealing lbterials and how the data generated for this activity is used as the basis for Canadian participation in the activities of the IS0 committee .
