conceito
The specification covers fiber – ou folhas de polímero não vulcanizado reforçadas com tecido feitas de polietileno clorossulfonado (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: grossura; Força de ruptura; Extend; Tear strength; Low temperature bending; Linear size change; Layer adhesion; Hydrostatic resistance; Ozone resistance; And weather resistance. Por outro lado, 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: resistência à tracção; Extend; Tear resistance; Ozone resistance; And water absorption.

Especificação padrão ASTM D5019-2011 para folhas CSM reforçadas (Polietileno Cloro-sulfonado) para filmes de telhado de camada única

Raio
1.1 This specification covers reinforced non-vulcanized polymer sheets (Veja a nota 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 Valores expressos em unidades do SI serão considerados padrão. Os valores dados entre parênteses são apenas para referência.

1.4 The following precautionary warnings relate only to the test methods section of Section 8 of this specification: Esta norma não se destina a abordar todas as questões de segurança, caso existam, associado ao seu uso. É responsabilidade dos usuários desta norma estabelecer práticas adequadas de segurança e saúde e determinar a aplicabilidade das restrições regulatórias antes do uso..
