Introduction

Buildings preformed seal conditions of use because of geographical differences or different roles and positions in buildings and different. The standards, according to various conditions experienced by sealing strips to determine material requirements. Also it takes into account the static sealing strips are subjected Stress state and dynamic stresses. Vulcanized rubber and thermoplastic rubber Building preformed seal classification, Requirements and test methods Warning. Use of this standard should be familiar with normal laboratory practice. This standard does not purport relates to the use of this standard may appear as There are security issues. Responsibility of the user to establish a special system of health and safety and to ensure compliance with national legislation.

1 Scope

This standard specifies the buildings preformed seal classification, performance and seal itself, some of the functional requirements and test phase Off test methods (see Appendix). This standard applies to preformed sealing strip of vulcanized rubber and thermoplastic rubber, these preformed sealing strip includes the following products. a) seal the doors and windows box, ie, doors and windows wind seal (dynamic seal); b) glazing seals (static seal); c) for sealing around the seal; d) for each part of the front sealing strip between buildings; e) for the seal between the brick walls. This standard is also applicable to the design temperature (heat condition of type P1) and designed for use at temperatures between -20 ℃ ~ + 55 ℃ in Between -40 ℃ ~ + 70 ℃ (heat condition type P3) sponge rubber sealing strip of said preform (see Chapter 4).
