konsep
The specification covers fiber – atau lembaran polimer non-vulkanisasi yang diperkuat kain yang terbuat dari polietilen terklorosulfonasi (CSM), intended to be used as a single-layer roof film exposed to weather. Kriteria desain untuk sistem atap di lokasi, seperti ketahanan terhadap api, field joint strength, impact/puncture resistance, material compatibility, and heave resistance, berada di luar cakupan Kode ini. The backing or reinforcement plate shall conform to the following physical properties: ketebalan; Breaking strength; Extend; Tear strength; Low temperature bending; Linear size change; Layer adhesion; Hydrostatic resistance; Ozone resistance; And weather resistance. Di samping itu, 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: daya tarik; Extend; Ketahanan sobek; Ozone resistance; And water absorption.

Spesifikasi Standar ASTM D5019-2011 untuk Lembar CSM yang Diperkuat (Polietilen terkloro-sulfonasi) untuk Film Atap Satu Lapis

Radius
1.1 This specification covers reinforced non-vulcanized polymer sheets (Lihat Catatan 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, seperti ketahanan terhadap api, field joint strength, impact/puncture resistance, kompatibilitas material dan ketahanan tarik, are factors that need to be considered but are beyond the scope of this specification.

1.3 Nilai yang dinyatakan dalam satuan SI harus dianggap standar. Nilai yang diberikan dalam tanda kurung hanya untuk referensi.

1.4 The following precautionary warnings relate only to the test methods section of Section 8 dari spesifikasi ini: Standar ini tidak dimaksudkan untuk mengatasi semua masalah keselamatan, jika ada, terkait dengan penggunaannya. Pengguna standar ini bertanggung jawab untuk menetapkan praktik keselamatan dan kesehatan yang sesuai dan menentukan penerapan pembatasan peraturan sebelum digunakan..
