NOTE 1—Re? Terminology 3. If curved, the length of such a blemish is to be measured from end to end along the curve. The values given in parentheses are for information only.

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. Referenced Documents 2. Current edition approved Oct.

Published October Originally approved in Last previous edition approved in as C — DOI: ASTM International. This includes glass with ultra high transmittance for additional clarity. Edge color of clear glass can vary so the glass manufacturer should be consulted regarding an application where edge color is an aesthetic consideration. General glazing applications. Production of general use mirrors and other applications.

Typical Use Production of architectural glass products including coated, heat treated, laminated, and other select glass products. Applications in which functional characteristics are a consideration and blemishes are not a major concern. Requirements Production of general use mirrors and other applications. Optional edge work can be speci? See 6. Nonrectangular shapes shall use the same thickness tolerances in Table 2. For linear straight line dimensions of nonrectangular shapes, the length and width requirements in Table 2 shall be used.

For curvilinear dimensions of nonrectangular shapes, tolerances shall be as agreed upon by the involved parties. Discoloration and slight distortion of wire are permissible.

Wired glass may contain numerous gaseous inclusions along the wire. Opening in the mesh shall not exceed 32 mm 11? Opening in the mesh shall not exceed 16 mm 5?

Check with the manufacturer for thickness and dimensional tolerances on random Pattern P3 and special Pattern P4. Scattered areas of non-uniform surface and scattered surface blemishes are permissible. NOTE 4—Patterned glass can vary slightly in both con? Glass edge requirements stated in this standard do not apply to Type II glass. Test Methods 6. View samples in the vertical position at the distance as speci?

The inspection shall then progress sequentially to each of the shorter distances for other applicable blemish intensities listed in Table Any blemishes detected from these distances shall be compared with the length and separation criteria for allowable blemishes given in Table 5. For blemish size ranges with different separation distance criteria, the minimum separation distance is determined by the minimum separation distance required for the larger of the two blemishes.

Blemishes in size ranges that are allowed without separation distance criteria shall not be compared with those that have separation criteria. Place sample, with the direction of the draw oriented vertically, at a distance of approximately 4. Start with the glass sample parallel with the zebra board identi? Refer to Table 6 for evaluation criteria. The lower of the two interference angles measured shall be used to compare to the evaluation criteria in Table 6.

The difference in length between the two diagonals D1—D2 shall not exceed the limits set forth in Table 2. Check with the manufacturer for more information. Measurements taken at any point shall meet the tolerance requirements of Table 7 or Table 8, or both. The allowable blemish sizes listed in Table 9 do not include associated distortion. Glass shall be viewed at distance of 1. As an alternate method, the thickness may be measured using two bars with? Package Marking 7. Keywords 8. Length and width of cut size and stock sheets of?
