ASTM E2190:2019 pdf download.Standard Specification for lnsulating Glass Unit Performance and Evaluation.
5.2 Glass Construction:
5.2.1 For double-glazed specimens: 4 mm (32 in.) nominal glass with 12 mm (1/2 in.) cavity, or 5 mm (/I6 in. ) nominal glass with 6 mm (¼ in.) cavity.
5.2.2 For triple-glazed specimens: 4 mm (32 lit) glass with
6 mm (¼ in.) cavities.
5.2.3 If the required glass constructions in 5.2.1 and 5.2.2 are not available from the submitting manufacturer, then thicker glass or wider cavities, or both, shall be allowed. (For example. using 6 mm glass with 12 mm cavity.) This may result in a more rigorous test.
5.2.4 All of the values noted in this section are nominal.
5.2.5 Tolerance of glass thickness shall he in accordance with Specification C1036.
5.2.6 Cavity tolerance shall he ±0.8 mm (½2 in.).
5.2.7 There shall he no internal components in the baseline set.
5.3 Glass Coatings (if used):
5.3.1 Coatings shall be included in the specimens, if the manufacturer uses coatings in normal production.
5.3.2 For double-glazing specimens, one lite of the spedmen shall be clear and the other shall have a coating applied to the inner surface.
5.3.3 For triple-glazed specimens tested to Test Method E2 188, both outer lites shall be clear glass and the middle lite shall have a metallic coating (either low E or reflective) on at least one surface.
5.3.4 For triple-glazed specimens tested to Test Method E2189 for the base set, one outer lite shall have a metallic coating (either low E or reflective). For specimens with internal components, the internal component shall he within the cavity with the metallic coating.
5.4 Number of Specimens in a Submitted Baseline Set:
5.4.1 Double-glazed with air or argon-filled units shall have
12 specimens per set.
5.4.2 Triple-glazed with air or argon-filled units shall have
14 specimens per set.
5.5 For qualifying specimens with argon gas fill, the specimens shall be made with the same gas-filling techniques as used for the manufacturer’s production.
5.6 Internal Components (if used):
5.6.1 If internal components are specified, supplementary testing to Test Method E2l89 is required.
5.6.2 Specimens in this supplementary testing to Test Method E2l89 shall he made with the internal components, using the exact same sealing system and geometry as the baseline set that was tested without internal components.
5.6.3 The specimens with internal components can be made at a different time than the baseline set.
5.6.4 There shall be three specimens (two tested, one spare) submitted for double-glazed IG and five specimens (four tested, one spare) submitted for triple-glazed 1G.
6. Test Methods
6. 1 Baseline Set Testing to Test Method E2 188:
6.1.1 In accordance with Test Method E2l88, prepare the specimens as directed and follow the testing procedure.
