ASTM C1021-08(2014) 建筑密封料测试用实验室的标准实施规程

4.1 Importance of Prequalification—For required accuracy of test results and reliability of certification, it is essential that testing laboratories be prequalified. This practice establishes those qualifications. 4.2 Contractual Relationships: 4.2.1 Although testing laboratories may be qualified in accordance with this practice, it is important for the contracting authority to consider the relationship of the testing laboratory with other interested parties before engaging the laboratory to perform the testing. The other interested parties in the project usually consist of the manufacturer of the material to be tested, the contractor (bidder), the owner of the project (user and contracting authority), and the architect who serves as the owner's agent in preparing the contract documents. 4.2.2 Many sealant manufacturers have their own qualified testing facilities that are used to conduct research and maintain quality control of their products. Generally, the companies that have such facilities are willing to certify as to the performance standards with which their products comply. The contracting authority should determine if there are conflicting interests in such a relationship. The contracting authority may prefer that the product testing to ascertain conformance with specific performance standards and the reporting of such testing be performed by a qualified but independent testing laboratory. The contract documents should make this requirement known so that bidders can bid accordingly. 4.2.3 The testing of each caulking and sealant for each and every project can be costly. On a small building project, the cost of testing, if required, may be more than the cost of the sealant materials. On a large project, on the other hand, the cost of testing a sealant with accompanying certification by a qualified independent testing laboratory may be small in comparison to the sealant materials and commensurate with the assurances desired by the contracting authority. 4.3 Requirements in Contract Documents : 4.3.1 In addition to specifying the performance standards that the caulking and sealants to be used on a project shall be in compliance with, state that proof of compliance shall be in the form of certification by a testing laboratory meeting the requirements of this practice. 4.3.2 If the contracting authority desires that the testing and certification be by an independent testing laboratory this additional requirement should be included with the requirements stated in 4.3.1. 1.1 This practice describes the qualifications, including minimum requirements for personnel and equipment, duties, responsibilities, and services of independent commercial materials testing laboratories engaged in the testing of caulking and sealants used in building construction. 1.2 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 and health practices and determine the applicability of regulatory limitations prior to use. 1.3 The subcommittee with jurisdiction of this standard is not aware of any similar or equivalent ISO standard.

ASTM D6381/D6381M-08(2013)e1 沥青盖屋板耐机械提升性测量的标准试验方法

5.1 Uplift resistance is one of the properties of an applied shingle that relates to its ability to withstand wind forces. The mechanical tests described are laboratory methods to measure that resistance at a designated temperature after the shingles have been sealed under designated conditions. 5.1.1 No quantitative relationship has been established between the mechanical uplift resistance and uplift forces due to the wind. 5.2 Many factors influence the sealing characteristics of shingles in the field; for example, temperature, time, contamination by dirt and debris, roof slope, and interference by misplaced fasteners. It is not the objective of this test method to address all of these influences. This test method is designed to determine the mechanical uplift resistance when representative specimens of shingles are sealed under selected conditions prior to testing. 5.3 Procedure A produces lower results than Procedure B. Procedure A provides an edge-lift load value and Procedure B provides a perpendicular load value. The procedure applicable to a specific product depends on the specific product design, geometry, and rigidity. It is the responsibility of the user of this test method to determine the appropriate procedure with reference to the specific product and application. It is possible that engineering calculations would require both procedures to be employed, and for both results to be used in the calculation of the resistance of that specific product to the effects of wind. 5.4 When using this method in conjunction with Test Method D7158 to determine the uplift resistance of shingles as part of the determination of wind resistance of the shingles, determine the appropriate procedure (Procedure A, Procedure B, or both) in accordance with the discussion, and examples, of shingle geometry and sealant configuration in Section 12.2 of Test Method D7158. 1.1 This test method covers measuring the uplift resistance of asphalt roofing shingles by mechanical means. It is applicable to shingles that use a factory-applied or field-applied sealant. 1.2 There are several types of shingles designed for service without a factory-applied or field-applied sealant. These shingles, when applied in accordance with the manufacturers'' application instructions, employ other means to provide resistance against the forces generated by the action of wind such as geometry and shingle construction. Field experience has shown that these types of shingles function satisfactorily in service. Because there are a variety of these shingle designs, it is not practical to describe in this test method how to test these shingles for uplift resistance. The testing of these types of shingles, therefore, goes beyond the scope of this test method. 1.3 This test method describes two procedures for measuring shingle uplift resistance. Procedure A employs a specially designed apparatus with a clamping device which facilitates lifting of the edge of the shingle and measuring the force required to break the seal. Procedure B employs a metal “T” section adhered to the weather surface of the shingle to facilitate application and measurement of a perpendicular force to break the seal. 1.4 It is not prohibited to use this test method over a range of sealing time and temperature combinations and testing temperatures to simulate a variety of actual field use conditions. The times and temperatures used shall be ......

ASTM C1643-08 测量气溶胶泡沫密封剂的后滴涂体积膨胀的标准试验方法

Post dispensing volumetric expansion factor F ¯ indicates the ratio of the fully cured foam sealant volume and the initially dispensed foam sealant volume. For example, if the expansion factor F ¯ were 2, the fully cured foam would double its initial volume; therefore, one should fill 50 % of the cavity uniformly to anticipate the full coverage upon curing. Post dispensing volumetric expansion factor F ¯ does not predict the performance capability of the foam sealants of the suitability for the intended applications. This test method is intended to lend guidance in product selection as related to the post dispensing expansion characteristics of the aerosol foam sealants. This test method recognizes that the results are reflective of controlled laboratory conditions. Post dispensing expansion in field applications may vary according to temperature, humidity, and surfaces that the aerosol foam sealants are in contact with.1.1 This test method measures the volumetric expansion of aerosol foam sealants after dispensing. 1.2 This test method provides a means for estimating the quantity of initial material required to dispense in order to fill a cavity. 1.3 Aerosol foam sealants are used for a variety of applications intended to reduce airflow through the building envelope. 1.4 This test method applies to two types of single component aerosol foam sealants: polyurethane and latex. 1.5 There are no other known standard test methods to measure aerosol foam sealants post dispensing expansion. 1.6 Values are reported in SI units only. Certain apparatus and supply items are referenced in inch-pound units for purchasing purposes. 1.7 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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D7349-08 确定屋顶和防水材料在紧固件周围密封的能力的标准测试方法

In some situations, penetration through asphalt-based roofing or waterproofing materials by fasteners is a required part of the material installation process or occurs during installation of other system components. When fasteners penetrate the material as a purposeful and planned part of the construction process, it is reasonable to expect that materials designed to limit migration of liquid water at the interface between the penetrating fastener and the material will do so. This qualitative test method provides a means to evaluate the ability of a material to limit water migration at fastener penetrations when tested under defined conditions.1.1 This qualitative test method determines the capability of asphalt-based roofing or waterproofing material to seal around a fastener that penetrates the material and prevent transmission of liquid water through the material at the penetration under defined conditions. 1.2 This test method is provided for adoption by ASTM or other consensus-based roofing and waterproofing product specifications as a standardized means to evaluate capability to seal around a fastener. Performance of this test method after subjecting the product to conditioning intended to simulate environmental stresses and strains is not prohibited. 1.3 The text of this test method references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.4 The values stated in SI units are to be regarded as standard. The values in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered 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 and health practices and determine the applicability of regulatory limitations prior to use.
