Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard uses the redrafted law to reference ISO 11617.2014 "Static curing of construction and civil engineering sealant elastomer sealants. Test specimens exposed to an artificial climatic environment and determination of changes in cohesive morphology and appearance after cyclic deformation", compiled with ISO 11617.2014 The degree of consistency is not equivalent. This standard is proposed by China Petroleum and Chemical Industry Federation. This standard is under the jurisdiction of the National Adhesive Standardization Technical Committee (SAC/TC185). This standard was drafted by. Guangzhou Synthetic Materials Research Institute Co., Ltd., Shanghai Rubber Products Research Institute Co., Ltd., Guangzhou Baiyun Chemical Co., Ltd. Industry Co., Ltd., Chengdu Sibao Technology Co., Ltd. Drafters of this standard. Yi Jun, Yin Yuming, Zhang Jianqing, Zeng Rong, Xie Yufang, and Chen Feng, Ren Shaozhi, and Shen Yan. Elastic sealant exposed to dynamic weathering Test method for changes in cohesive morphology

1 Scope

This standard specifies the test method for the change of cohesive morphology after exposure to artificial weathering. This standard applies to the appearance of dynamic aging of elastic sealants, the number, width and depth of cohesive cracks.

3 Terms and Definitions

The following terms and definitions as defined by ISO /IEC 14598 apply to this document. 3.1 Dynamic Artificial Weather Aging dynamicartificialweathering After the static sealant is cured, the elastic sealant is exposed to the aging process of the artificial climate environment and the cyclical tensile/compression cycle. 3.2 Cohesive morphological change changesincohesion After the dynamic weathering of the sealant, due to the change of cohesive strength, the appearance change caused by sealant is mainly manifested in the crack of the sealant. The number, width, and depth of lines vary.

4 Overview

The test sealant is adhered between the two parallel surfaces of the bracket to make a sample. After the state of the sample has been adjusted, insert a stopper at one end of the sample so that one end is in tension and the other end is in compression. Specimens are exposed to an artificial climate (light, heat and humidity) and the position of the stopper is changed once a week (the stopper is replaced from the end of the specimen. ......
