1. Scope
1.1 This test method describes a laboratory procedure for determining extensibility for one- or two-component cold liquid-applied elastomeric waterproofing membranes. 1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other orga- nizations. 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 appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions—Refer to Terminology C717 for definitions of terms used in this standard.
4. Comparison to Other Standards
4.1 The committee with jurisdiction over this standard is not aware of any comparable standards published by other orga- nizations.
5. Summary of Test Method
5.1 This test method consists of preparing three samples for each membrane to be tested and extending after aging 14 days at 70 6 2 °C (158 6 3.6 °F).
6. Significance and Use
6.1 This test method is used to determine a membrane’s ability to bridge a crack that forms after the membrane has been applied and allowed to cure.
7. Apparatus
7.1 Forced Draft Oven, controlled to 70 6 2 °C (158 6 3.6 °F). 7.2 Three Mortar Test Blocks, dimensions 12 × 76 × 152 mm ( 1 ⁄ 2 × 3 × 6 in.) nominal with 6 mm ( 1 ⁄ 4 in.) deep notch cut across the width (see Fig. 1). 7.3 Masking Tape. 7.4 Sand. 7.5 Wood Board, Steel Wedge, Hammer, and Wood Blades. 7.6 Testing Machine, with tension grips capable ofpulling at a rate of separation of 12.7 mm (0.5 in.)/min. 7.7 Vernier Calipers.
8. Conditioning/Mixing
8.1 Unless otherwise specified by those authorizing the test, standard conditions are 23 6 1 °C (73.4 6 1.8 °F) and 50 6 5 % relative humidity. 8.2 Store all membrane materials to be tested in an un- opened container at standard conditions for at least 24 h before any test specimens are prepared.8.3 Follow the manufacturer’s instructions for mixing and preparing membrane materials for testing. Thoroughly stir one-component materials before using. Mix two-component compounds in the ratio recommended by the manufacturer. If required by the manufacturer, mix each component prior to the final mix.
9. Procedure
9.1 Prepare three test specimens for each membrane to be tested as follows: 9.1.1 Cut each of the three mortar slabs crosswise in the center of the 152 mm (6 in.) length to a depth of 6 mm ( 1 ⁄ 4 in.), as shown in Fig. 1. N OTE 1—Mortar substrates must be prepared according to Guide C1375. 9.1.2 Measure the thickness of each block to the nearest 0.025 mm (0.001 in.) on each side of the center notch, using vernier calipers. Mark the location where the measurements were taken for future use. Record these values. 9.1.3 Mark the edge of each slab along the 152 mm (6 in.) length so that the bench marks are 51 mm (2 in.) apart and approximately 25 mm (1 in.) on each side of the center cut as shown in Fig. 1. 9.1.4 Apply masking tape across the ends ofthe uncut 76 by 152 mm (3 by 6 in.) faces of the slabs, leaving an exposed 76 by 102 mm (3 by 4 in.) area on each where the membrane may be applied. 9.1.5 For self-leveling membrane materials, lay the slabs on a bed of sand and level them. N OTE 2—For self-leveling membranes, apply 50 mm (1 in.) wide masking tape around the slab perimeter. The tape should protrude above the slab surface on all four sides to form a dam. 9.1.6 Apply sufficient membrane material to yield a dry film thickness of1.52 6 0.13 mm (60 6 5 mils) to the exposed area on the slab. Check the membrane thickness with a wet film gauge. The film thickness may be built up in multiple coats if specified by the manufacturer. Allow the three specimens to cure for 14 days at standard conditions (see 8.1). N OTE 3—Prior to application, the non-volatile content or application rate must be known. Perform Test Method C1250 to determine non- volatile content or contact the manufacturer for required information. N OTE 4—An alternative thickness can be tested and must be reported in the test report.
