Below is a description of a variety of ASTM standard specifications and the liners that meet those classifications.

 In brief, ASTM E84 tests the comparative surface burning behavior of exposed building materials such as walls and ceilings. The test is conducted with the specimen in the ceiling position with the surface to be evaluated exposed face down to the ignition source. The purpose of this test method is to determine the relative burning behavior of the material by observing the flame spread along the specimen. Flame spread and smoke developed index are reported.

Polyethylene sheeting that passes ASTM E84 are:

Dura-Skrim 2 FR, 10FR

Poly Scrim 6FR, 8FR, 10FR, 12 FR PVC, 14FR,

In brief, ASTM E96 test for reliable values of water vapor transfer (WVT) through permeable and semi-permeable materials, such as plastic sheeting.  A permeance value obtained under one set of test conditions may not indicate the value under a different set of conditions.

Polyethylene sheeting that passes ASTM E96 are:

Dura-Skrim 2 and 2 FR, 10FR

Dura-Skrim 6 BB, 6WB, 6WW

Dura-Skrim 8 BB, 8 WB, 12BB, 12 WB

Canvex C95WB

Rufco 2010B

Rufco 2000B, 3000B, 4000B, 300

VaporBlock 6, 10, 15

Dura-Skrim 10HUV and 10FR

Poly Scrim 6, 6FR, 8LD, 8FR,8HD, 10FR, 10, 12, 14, 14FR,15, 20,

 

 

ASTM D7004 evaluates grab tensile properties of reinforced geomembranes for the purposes of quality control, quality assurance and research. In order to evaluate the full contribution of the reinforcement, testing is performed parallel to the directions of reinforcement. This method is an index test and is not intended for design purposes.

Reinforced Plastic Sheeting/Polyethylene that passes ASTM D7004:

Dura-Skrim 2 and 2 FR, 10FR

Dura-Skrim 6 BB, 6WB, 6WW

Dura-Skrim 8 BB, 8 WB, 12BB, 12 WB

Dura-Skrim 10HUV

ASTM D4533 is the trapezoid tear method test that produces tension along a reasonably defined course such that the tear propagates across the width of the plastic sheeting.  The maximum trapezoid tearing strength is reached when the resistance to further reorientation is greater than the force required to rupture one or more fibers simultaneously.

Scrim Reinforced Plastic Sheeting that passes the ASTM D4533:

Poly Scrim 6, 6FR, 8LD, 12,12 FR PVC, 14FR,

Dura-Skrim String Reinforced poly liners

ASTM D2582 looks at the tear resistance of plastic sheeting when it is exposed to sharp objects that can puncture the sheeting. The test is the puncture-propagation of tear test which measures the resistance of a material to snagging, and to dynamic puncture and propagation of that puncture resulting in a tear. Failures due to snagging occur in a variety of end uses, including  tarpaulins.

Experience has shown that for many materials puncture does not contribute significantly to the force value determined, due to the sharpness of the propagating probe used. However, comparing the results of prepunctured test specimens with normal nonpunctured specimens will give an indication of the extent of any puncture resistance in the reported result.

The ASTM E1745 specification covers flexible, plastic sheeting to be used as vapor retarders in contact with soil or granular fill under concrete slabs. The specified tests are conducted on new materials and materials that have been conditioned or exposed to simulate potential service conditions. The membranes are classified and tested into 3 classes:

• water vapor permeance
• tensile strength
• puncture resistance

Under special conditions, the material shall also conform to the required flame spread, permeance after soil poison petroleum vehicle exposure, and permeance after exposure to ultraviolet light.

Vapor Retarders (barriers) that pass ASTM E 1745:

Dura-Skrim 6 BB, 6WB, 6WW  (Class C)

Dura-Skrim 8 BB, 8 WB, 12BB, 12 WB  (Class C)

VaporBlock 6 (Class C), 10 (Class A,B,C), 15 (Class A,B,C)

VaporBlock 20 Plus (Class A,B,C)
