Standards New Activity Report Form (SNARF)
Date Prepared: 06/01/2020Revised (if Applicable): 11/01/2021

Document Number: 6671
SNARF for: Revision to SEMI PV63-0215，Specification for UL TRA-THIN Glasses Used for Photovoltaic Modules

Originating Global Technical Committee: Photovoltaic
Originating TC Chapter: China
Task Force (TF) in which work is to be carried out: PV Module Task Force
Note: If a new task force is needed, also submit a task force organization form (TFOF)

___________________________________________________________________________
1. Rationale:
a. Describe the need or problem addressed by this activity.
(Indicate the customer, what benefits they will receive, and if possible, quantify the impact on the return on investment [ROI] if the Document is implemented.)

SEMI PV63 is due for Five Year Review. And this standard is very useful for PV industry.
Some performance and parameters have been adjusted, so we need to apply for revision.



b. Estimate effect on industry.
2: Major effect on an industry sector - identify the relevant sector
Sector or Company Information: Solar module material manufacturer and solar module manufacturer

c. Estimate technical difficulty of the activity.
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible

2. Scope:
a: Describe the technical areas to be covered or addressed by this Document development activity. For Subordinate Standards, list common concepts or criteria that the Subordinate Standard inherits from the Primary Standard, as well as differences from the Primary Standard:

1. 5.3.1 Expand the glass thickness range from 1.6mm to 3mm.
2 6.6.1During measurement, the sample shall be placed close to the rock plate or the plate with the same accuracy, and the rock plate shall be placed at an angle of 5 ° ± 2 ° with the vertical plane, as shown in Figure 2. Put an edge ruler or metal wire close to the two sides or diagonal of the glass. And test the gap between straight line and the glass by feeler. The degree of bow is then expressed as the deformation, divided by the measured length of the edge of the glass, or diagonal.
3 6.6.2 Local bow shall be measured over a limited length of 300 mm by using an edge ruler or a metal line. As shown in Figure4, degree of local bow is represented by the height of the trough or crest by using a feeler. No measurement shall be made in the area of 150mm at the edge .The measurement shall be carried out at room temperature.
4 6.10.3 Subject the glass product to an impact to the surface resulting from a smooth steel sphere weighing 227 g falling through a distance of 800mm.
5 6.12.1 Samples shall be maintained for at least 4 h at a temperature of 150°C ± 2°C in the oven.
6 Delete : 6.13.3 As for heat strengthened glass, the examination for ‘island’ and ‘particle’ shall be completed within 5 minutes of fracturing the glass. ‘Island’ and ‘particle’ are shown in Figure 4. Samples shall be examined for its fragmentation pattern. An area of radius 100 mm, centered on the impact point, and a border of 25 mm, round the edge of the test sample, shall be excluded from the assessment.
Add thickness difference when T is between 1.6 and 2.

8.12 Fragmentation
8.12.1 For heat strengthened glass, fragment produced during the test shall be assessed as follows:
1. At least one edge of the fragment shall reach the excluded area.
2. When no edge of the fragment reaches the excluded area, either an ‘island’ or a ‘particle’ is produced. There shall be less than three ‘islands’. Area of all the ‘island’ and ‘particle’ shall not be larger than 500 mm2.
8.12.2 For tempered glass, there shall not be less than 40 particles in every 50 mm × 50 mm areas of the sample. A few of long particles are allowed. But the length of the long particle shall not exceed 100 mm.
10.2 All the samples shall pass the test of optical property, iron content and fragmentation.

5. Safety Considerations:
The resulting document is expected:
NOT to be a Safety Guideline

NOTE FOR "to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is NOT technically sound and complete - Refer to Section 15.1 of the Regulations for special procedures to be followed.

NOTE FOR "NOT to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is still technically sound and complete.

___________________________________________________________________________
6. Intellectual Property Considerations:
Note: Both a: and b: below should be checked for Revision of existing Standard(s) and Safety Guideline(s).

a. For a new Standard or Safety Guideline and for any part to be modified or added in a Revision of published Standards and Safety Guidelines:
the use of patented technology is NOT required.

If "patented technology is intended to be included in the proposed Standard(s) or Safety Guideline(s) " is selected above, then also check one:


b. For Revision, Reapproval, Reinstatement, or Withdrawal of existing Standard(s) and Safety Guideline(s):
there is no known material patented technology necessary to use or implement the Standard(s) and Safety Guideline(s)

c. The body of the Document and any Appendices, Complementary Files, Related Information sections, or Various Materials that may or may not be a part of the Document by reference:
the incorporation of Copyrighted Item will NOT be required



NOTE FOR ‘the use of patented technology or the incorporation of Copyrighted Item(s) is NOT required’: If in the course of developing the Document, it is determined that the use of patented technology or Copyrighted Item(s) is necessary for the Document, the provisions of Regulations § 16 must be followed.

NOTE FOR ’will incorporate Copyrighted Item’: A copyright release letter must be obtained from the copyright owner prior to publication.
