concept
The specification covers fiber – o fogli polimerici non vulcanizzati rinforzati con tessuto realizzati in polietilene clorosolfonato (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: spessore; Forza di rottura; Extend; Tear strength; Low temperature bending; Linear size change; Layer adhesion; Hydrostatic resistance; Ozone resistance; And weather resistance. D'altra parte, 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: resistenza alla trazione; Extend; Resistenza allo strappo; Ozone resistance; And water absorption.

ASTM D5019-2011 Standard Specification for Reinforced CSM Sheets (Chloro-sulfonated Polyethylene) per pellicole per tetti monostrato

Raggio
1.1 This specification covers reinforced non-vulcanized polymer sheets (see note 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 I valori espressi in unità SI sono considerati standard. I valori indicati tra parentesi sono solo di riferimento.

1.4 The following precautionary warnings relate only to the test methods section of Section 8 of this specification: Questo standard non è destinato ad affrontare tutti i problemi di sicurezza, se presente, legati al suo utilizzo. È responsabilità degli utenti di questo standard stabilire adeguate pratiche di sicurezza e salute e determinare l'applicabilità delle restrizioni normative prima dell'uso.
