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.)
Reliability is an issue that is particularly important in the PV industry, since a module manufacturer has to guarantee a lifetime up to 25 years. The buyers invest their money on both the performance and reliability of the product. Prior tests to ensure that the module can withstand the environmental conditions before being sent off to the customers are, therefore, the most promising solution to minimize the cost of both the customers and the manufacturer. This standard aims to provide a common test method for simulation of the mechanical vibration occurring during transportation and shipping. The module makers and buyers, or any other party interested, can thus have a common testing standard to refer to when desired. The standard can also accelerate the development for safer means of module protection during transportation.

Standard vibration and shock test methods exist for many electrical products, however, not specifically for PV modules. Therefore, as the PV industry grows at an increasing rate (from 10 GW global shipment in 2009 to a predicted 25 GW in 2012 [1]), such a standard to eliminate the unnecessary loss of investment and profit is more desired than ever. The data from TÜV Rheinland show that 9% of the c-Si modules and 13% of the Thin-Film modules arrived in the lab for testing in 2007-2008 failed during the initial measurement (insulation, power measurement and visual inspection, etc). Since the module makers perform some of these tests themselves before shipping, the data suggest that around 10% of modules were significantly damaged during transportation, caused most likely by vibration and shock. It is also possible that the ones that did not fail the initial measurement failed the other tests due to the same reason. Moreover, it is unknown whether the lifetime of those modules that pass the tests would not be shortened.

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:

This standard aims to provide a standard test method, as well as a common literature, when the reference to PV module reliability and safety test method against vibration in shipping environment is needed. It will benefit the module manufacturers, the buyers, the package providers/developers, and the PV module testing laboratories.

The new standard will specify:
a. Basic vibration test system requirements
b. Fixation of the packaged modules on the shaker
c. Fixation of the accelerometers on the modules
d. Test conditions for shipping via sea, air and land.

This standard will not:
a. Restrict the design specifications of the package other than at the interface to the test system, in order to enable b. the mounting of the package to the shaker.
c. Specify the orientation of the modules.

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 14.1 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.
