v
manufacturers. Hewlett-Packard has no control over such changes. The entire

Mthough testing helps to characterize an envelope's performance, long-term
satisfaction requires process qufllty control by the envelope's manufacturer and
proper handling until use.
Envelopes should meet the specifications Ested in the following table
