Photography. Processing chemicals. Specifications for p-methylaminophenol sulfate Ingestion-build-48974 “Corrosion” and “delamination” was changed

“Corrosion” and “delamination” was changed to “corroded area” and “delaminated area”

This helps you in determining the manganese content using the flame atomic absorption spectrometric method (FAAS) for copper and copper alloys

BS EN 12814-4 helps to check the welding joints of thermoplastic material using a peel test

The conditions of this test (for example amount of inoculum and substrate in the test bottles) were adopted to a defined test period over several days
