ASTM C1306/C1306M-08(2023)(Test Method)
Standard Test Method for Hydrostatic Pressure Resistance of a Liquid-Applied Waterproofing Membrane

SIGNIFICANCE AND USE
5.1 This test method is used as a screening tool to determine the hydrostatic pressure to which a liquid-applied waterproofing membrane may be subjected without failing when stretched over a crack in the substrate. This test method discriminates between a membrane that is very resistant to hydrostatic pressure and one that is not. Because of the variability inherent in this test method, it is not recommended that this test method be used to set a numerical standard for hydrostatic pressure resistance. No prediction of durability at lower hydrostatic pressures can be made when using the results of this test method.
SCOPE
1.1 This test method describes a laboratory procedure for determining the resistance of a waterproofing membrane to hydrostatic pressure.  
1.2 The committee with jurisdiction over this standard is not aware of any comparable standards published by other organizations.  
1.3 There are no ISO standards similar or equivalent to this ASTM standard.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SCOPE
1.1 This test method covers a laboratory procedure for determining the ability of a waterproofing membrane to bridge a crack in the substrate.  
1.2 There are no ISO standards similar or equivalent to this ASTM standard.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM D3805/D3805M-16(2023)(Guide)
Standard Guide for Application of Aluminum-Pigmented Asphalt Roof Coatings

SIGNIFICANCE AND USE
3.1 Asphalt-based, solvent-type, fibered or nonfibered, aluminum-pigmented roof coatings are used as a protective coating for solar reflection to prolong the life of roofing materials or where decorative qualities are desired.  
3.2 Suitable application of aluminum-pigmented asphalt roof coatings is an important factor in achieving a successful long-term coating. Suitable application is, in part, dependent upon appropriate specifications to guide the work. This guide can be useful in facilitating development of an appropriate specification for surface preparation and application of the roof coating.  
3.3 Designers/specifiers of coatings may use this guide in preparing the application portion of their specification. Contractors working directly for the building owner may also use this guide.  
3.4 This guide is not all-inclusive. Manufacturer's application instructions should be consulted and geographical “area practices” considered. Consult membrane manufacturer and coating manufacturer for acceptability of procedures and products.
SCOPE
1.1 This guide covers the application methods for Specification D2824/D2824M Aluminum-Pigmented Asphalt Roof Coatings, Nonfibered, and Fibered without Asbestos, for application on asphalt built-up roof membranes, modified bitumen roof membranes, bituminous base flashings, concrete surfaces, metal surfaces, emulsion coatings, and solvent-based coatings. This guide does not apply to the selection of a specific aluminum-pigmented asphalt roof coating type for use on specific projects. The fibered version of these coatings excludes the use of asbestos fibers.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 4.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

SCOPE
1.1 This practice is a guide for removing test specimens from existing built-up roofing systems in the field and for determining the approximate quantities of the components of that specimen (Note 1). Components determined may be:  
1.1.1 Insulation components when they are part of the roof membrane system,  
1.1.2 Plies of roofing felt,  
1.1.3 Interply layers of bituminous material,  
1.1.4 Top coating, and  
1.1.5 Surfacing.  
Note 1: This procedure is for the investigation of existing roofs and is not intended for new construction inspection.  
1.2 This practice is applicable to both 914 mm [36 in.] and 1000 mm [393/8 in.] wide felt rolls.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM D1670/D1670M-11(2023)(Test Method)
Standard Test Method for Failure End Point in Accelerated and Outdoor Weathering of Bituminous Materials

SIGNIFICANCE AND USE
4.1 The extent of cracking or pitting of bituminous films is a measure of the extent of deterioration due to weathering. Failure due to cracking is more accurately determined electrically than visually.  
4.2 Failure determined by this test method will depend not only on the characteristics of the bituminous material and the extent of weathering, but also on the film thickness, and the amount and type of mineral filler present.  
4.3 Tests on a similar material of known weathering characteristics (a control) exposed at the same time as the test material is strongly recommended as a check on the validity of the test results.
SCOPE
1.1 This test method covers the use of a spark-generating apparatus for determination of failure due to cracking of bituminous materials undergoing accelerated or outdoor weathering on electrically conductive backings.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
