ASTM D5019-2011 Standard Pagtutukoy para sa Reinforced CSM Sheets (Polyethylene na may insulin na chloro) para sa Single-layer Roof Films

concept
The specification covers fiber – o tela reinforced non-vulcanized polymer sheet na ginawa mula sa chlorosulfonated polyethylene (CSM), intended to be used as a single-layer roof film exposed to weather. Design criteria for on-site roof systems, such as fire resistance, field joint strength, impact/puncture resistance, material compatibility, and heave resistance, are beyond the scope of this Code. The backing or reinforcement plate shall conform to the following physical properties: thickness; Breaking strength; Extend; Tear strength; Low temperature bending; Linear size change; Layer adhesion; Hydrostatic resistance; Ozone resistance; And weather resistance. Sa kabilang banda naman, the coated part of the weather-resistant side of the plate contains neither backing nor internal reinforcement materials, and should adhere to the following physical properties: lakas ng paghatak; Extend; Tear resistance; Ozone resistance; And water absorption.

Radius
1.1 This specification covers reinforced non-vulcanized polymer sheets (tingnan sa tala 1) made from chlorosulfonated polyethylene (CSM), intended for use as a single layer roof film exposed to weather. The sheet shall be reinforced with fiber or fabric.

The term CSPE is commonly used in the roofing industry.

1.1.1 The polymers used in these sheets have thermoplastic properties when installed. The chlorosulfonated polyethylene will be vulcanized in situ under environmental conditions.

1.2 The test and performance limits used to characterize these sheets are minimum.

1.2.1 Design criteria for cast-in-place roof systems, such as fire resistance, field joint strength, impact/puncture resistance, material compatibility and pull resistance, are factors that need to be considered but are beyond the scope of this specification.

1.3 Values expressed in SI units shall be considered standard. Ang mga halaga na ibinigay sa mga panaklong ay para sa sanggunian lamang.

1.4 The following precautionary warnings relate only to the test methods section of Section 8 of this specification: Ang pamantayang ito ay hindi nilayon upang matugunan ang lahat ng mga alalahanin sa kaligtasan, kung meron man, na nauugnay sa paggamit nito. Responsibilidad ng mga gumagamit ng pamantayang ito na magtatag ng angkop na mga kasanayan sa kaligtasan at kalusugan at upang matukoy ang pagiging angkop ng mga paghihigpit sa regulasyon bago gamitin.
