What Test: Standard Guide for Evaluating the Filming and Streaking of Glass Cleaners – HCPA (CSPA) Designation DCC-09A

Why This Test: This test is used to evaluate a glass cleaning product’s performance under the categories of streaking and filming. Evaluation is based on rating scales completed by a trained panel of judges.

Results: The results may be used for informing formulation, performance evaluation, and product comparison.


 

Perhaps your cleaner is excellent at removing dirt from glass, but that’s not the only determining factor in a good consumer experience with your product. If a formulation causes heavy streaking or filming, this may appear just as dirty to a consumer as soil does.

The standard method HCPA DCC-09A is a test we use at Dell Tech to evaluate glass cleaners and is a companion test to the HCPA DCC-09 method.

In this test, clean mirror tiles are wiped with glass cleaners. The mirror tiles are qualitatively rated by a trained panel of judges based on the attributes of:

  1. Filming – overall cloudiness or haziness.
  2. Streaking – product residue left behind (dried droplets or strings of droplets).

Judges rate the attributes of each sample tile against prepared reference tiles. The average for each attribute rating and the standard deviation is compiled into a file report. A client may wish to test a single sample or compare multiple samples under the same test conditions and judging.
