5.1 Laminates are made by bonding together two or more layers of material or materials, where each layer might be a single or multi-layer material. When the bonding agent is reactive and requires time to reach full performance, the bond strength is typically measured as a green (un-cured) bond and a cured bond. For processes that intentionally create a nonlaminated edge, that edge is generally used to initiate the bond strength measurement. The techniques described in this practice can be used to initiate separation of plies when a non-laminated edge is not present.1.1 This practice describes techniques for separating plies of laminates made from flexible materials such as cellulose, paper, plastic film, and foil to enable the measurement of the bond strength or ply adhesion of the laminate. This includes laminates made by various processes: adhesive laminates, extrusion coatings, extrusion laminates, and coextrusions.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.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 6.1.1.1.4 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.

5.1 Pummel adhesion of laminated glass is a method used to measure the relative adhesive bond strength between the interlayer and glass substrate interface. The interlayer to substrate adhesion has a great effect on the impact resistance of laminates as well as long term stability. This test method is intended to provide three levels of grading. This test method is not intended to provide more precision. The laminate bond strength, in most applications, must be controlled to avoid potential problems of delamination at low adhesion and impact failures or undesirable post breakage characteristics at high adhesion.1.1 This test method determines the relative strength of the adhesive bond between interlayer and glass, inks, coatings, frit or other materials adhered to the glass surface to which interlayers may bond (hereinafter, glass substrate).1.2 This test method outlines a test method to be used on laminated architectural glass with two layers of glass substrate bonded by an interlayer. Glass substrate can be undecorated, decorated, uncoated, coated, annealed or strengthened, flat or patterned. One or more of the surfaces of glass may have a surface with ink, coatings, frit, patterns, a low-e type coating etc.1.3 This test method is a qualitative test which covers manual and semi-automatic mechanical pummel testing and visual rating of tested specimens.1.4 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units 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.

5.1 It is generally recognized that excess moisture and air within an interlayer will cause bubble formation in a laminate when exposed to heat or UV radiation, or both. These may be caused by initial moisture and air in the interlayer and be generated by thermal exposure. The purpose of this test method is to measure quantitatively the laminate stability under controlled conditions, specifically in relation to the formation of bubbles in the body of the laminate.5.2 Subjecting the laminated glazing to extended heat at a controlled temperature and time provides the excess moisture and air which are forced into the interlayer during processing to surface as bubbles. This occurs only if there are excess moisture and air trapped in between the glass. Therefore, making these thermal tests efficient to determine proper de-airing of laminated glass products.5.3 This test method provides a means to visually determine if discoloration has or is occurring and serves as a pass/fail test for some aspects of lamination quality.5.4 This test method can be performed after natural or accelerated exposure to determine if there are changes to the polymer such as the stability with high temperature which is useful for understanding the visual stability of installed glazing.5.5 This test method does not provide an indication of laminated glass capability for impact resistance, glass shard retention on breakage or edge stability of laminated glass.1.1 The purpose of this test method is to measure quantitatively the laminate stability under controlled conditions, specifically in relation to the formation of bubbles in a laminate with heat exposure.1.2 This test method can be performed on laminates which have been exposed to weathering or as manufactured samples to determine the amount of excess air dissolved in the interlayer.1.3 This test method determines the stability of laminated glass when subjected to high heat environments.1.4 This test method outlines a procedure to be used on laminated glass with two or more layers of glass bonded by an interlayer.1.5 This test method covers visual rating of tested specimens.1.6 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.

4.1 For molded phenolic products, acetone extraction shall be considered solely as a quantitative expression of a property normally associated with degree of cure. There is no demonstrably rigorous relation between the optimum mechanical and electrical properties of a well-cured piece and the numerical value of the acetone test. The amount of acetone-soluble matter is affected by: (1) nature of resin and filler, (2) lubricant, (3) molding temperature, (4) length of cure, (5) thickness of the section from which sample is taken, (6) nature of molded piece, (7) technique used in molding, (8) distribution of fines in the material to be extracted, and (9) method of grinding the specimen. These variations under some conditions will cause a difference of 3 to 4 % in acetone-extractable matter. For this reason, the test method shall be used only as a comparative test for measuring undercure.4.2 For laminated phenolic products, acetone extraction indicates change in stage of cure, change in resin content, change in type of resin used, presence of plasticizers or other acetone-extractable addition agents, and is affected in general by the same factors as stated in 6.11.1 This test method covers the determination of the amount of acetone-soluble matter in molded or laminated phenolic products.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered 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.NOTE 1: This test method is similar to ISO 308.1.4 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.

5.1 This practice provides a design load suitable for sizing blast resistant glazing comprised of laminated glass or insulating glass fabricated with laminated glass.5.2 Blast resistant glazing comprised of laminated glass or insulating glass fabricated with laminated glass shall be sized to resist the 3-second duration equivalent design loading from this standard practice using the procedures described in Practice E1300.5.3 In the event a blast loading does not occur to blast resistant glazing comprised of laminated glass or insulating glass fabricated with laminated glass sized using the 3-second duration loading determined herein, the blast resistant glazing will have a probability of breakage less than or equal to 8 lites per 1000 at the first occurrence of a loading equal to the 3-second duration design loading determined herein.5.4 Blast resistant glazing designed to resist the 3-second equivalent load as determined herein, when properly supported as part of a blast resistant glazing system, is designed to perform to minimal hazard as defined in Test Method F2912.1.1 This practice sets forth a method to specify an equivalent 3-second design loading suitable to use with Practice E1300 to select the thickness and type of blast resistant glazing fabricated with laminated glass to glaze a fenestration. Glass plies used to construct laminated glass are recommended to be either annealed or heat strengthened glass. This analytical method for glazing should be used with caution for glazing panels larger than 1.8 m by 2.4 m (6 ft by 8 ft) as this size panel exceeds database of testing upon which this standard is based.1.2 This practice applies to blast resistant glazing fabricated using laminated glass only, including single laminated glass and insulating glass fabricated with laminated glass. As a minimum, insulating glass shall use laminated glass for the inboard (protected side) lite.1.3 This practice assumes that blast resistant glazing shall be attached to its supporting frame using a captured bite so that it does not detach in the event of fracture due to a blast event.1.4 Blast resistant glazing designed using this practice recommends the use of annealed or heat strengthened glass plies for the laminated glass. Blast testing has shown that use of fully tempered glass plies, when fractured during a blast event, have poorer post blast performance than annealed or heat strengthened glass plies. Laminated glass fabricated with fully tempered glass plies has a tendency to leave the supporting glazing system frame after fracture whereas laminated glass fabricated with annealed or heat strengthened glass plies will remain in the frame and absorb remaining load through tensile membrane behavior. Use of the annealed or heat strengthened glass plies will also reduce the amount of load transferred into the structure.1.5 The equivalent 3-second design load as determined herein shall not apply to the design of monolithic glazing, plastic glazing, or security film applied to existing glazing configurations in an attempt to achieve blast resistance.1.6 The values stated in SI units are to be regarded as the standard. Values given in parentheses are for information only. For conversion of quantities in various systems of measurements to SI units refer to ANSI IEEE/SI 10.1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use.

10.1 Full-scale bending testing is an effective way to determine flexural properties of structural glued laminated timber (glulam) beams. However, testing of large glulam members is cost prohibitive. Mathematical models, when confirmed by full-scale test results, are useful tools to assign flexural properties for glulam. This practice provides guidelines for sampling and testing full-scale glulam beams to determine their flexural properties and to validate mathematical models intended for use in assigning flexural design values.1.1 This practice describes procedures for full scale testing of structural glued laminated timber (glulam) to determine or verify characteristic values used to calculate flexural design properties. Guidelines are given for: (1) testing individual structural glued laminated timber lay-ups (with no modeling), (2) testing individual glulam combinations (with limited modeling), and (3) validating models used to predict characteristic values.1.2 This practice is limited to procedures for establishing flexural properties (Modulus of Rupture, MOR, and Modulus of Elasticity, MOE). Some of the principles for sampling and analysis presented may be applicable to other properties. However, other properties may require additional testing considerations that are beyond the scope of this practice.1.3 This practice is not intended to supersede the provisions of Practice D3737, but provides an alternative method for establishing characteristic values. Lay-up combinations developed in accordance with Practice D3737 are not required to be governed by this standard.NOTE 1: The models described by Practice D3737 have been developed and modified based on more than 50 years of experience and many test programs. In some cases, however, it may be desirable to develop a new model based on other input properties or using lumber materials or grades not covered by that standard.1.4 Details of production, inspection, and certification are beyond the scope of this document. However, for test results to be representative of production, quality control systems shall be in place to ensure consistent quality. Manufacturing shall conform to recognized manufacturing standards such as ANSI A190.1 or CSA O122.1.5 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use.

3.1 This test method is designed to compare related laminated composite gasket materials under controlled conditions and their short-time compressibility and recovery at room temperature. It measures compressibility with a matched pair of opposing upper and lower penetrators which provide better precision and bias than methods using an upper penetrator and a lower anvil. It is difficult to prepare undistorted test specimens from laminated composite gasket materials which will lay flat on an anvil. Also, with many composites having rigid inner layers the load on the upper penetrator is distributed over the bottom anvil area resulting in a lower than actual compressibility reading. This test method may be used as a routine test method when agreed upon between the purchaser and the producer.1.1 This test method covers determination of the short-time compressibility and recovery at room temperature of laminated composite gasket materials.1.2 This test method is not intended as a test for compressibility under prolonged stress application, that is “creep,” or for recovery following such prolonged stress application, the inverse of which is generally referred to as “compression set.” Also, it is only intended for tests at room temperature.1.3 The values stated in SI units are to be regarded as the standard.
