Peel testing in force measurement can be rather open-ended in terms of how the standard operating procedures (SOP) can be written. Examples of lengthwise testing may include something as common as tape reels to as uncommon as aircraft decals – yet the methods for testing one in comparison with the other can be mistaken for being functionally identical. Some standards, such as ASTM D3330, refer to multiple methods for testing similar samples, so the issue when designing an SOP for measuring force application becomes discerning what test method to utilize. Consideration must be given to the conditions that the materials will be exposed to, necessitating understanding of both the procedure setup and data analysis.
