b. Verify that black light intensities are within acceptable limits.
a. Verify that removal of developer residues is accomplished in a satisfactory manner.
b. Verify that removal of penetrant residues is accomplished in a satisfactory manner.
Control Of New Materials.
Newly Received Materials.
Penetrant system materials (penetrants, emulsifiers and removers, and wet and dry developers) are compounded or
formulated in batches or lots. It is possible for one batch or lot among several to have characteristics that do not meet
the specification requirements. Therefore, each batch or lot of penetrant, emulsifier and remover, and wet and dry
developers SHALL be tested on receipt, prior to in-service use. Quality conformance tests for newly received materials
are described in paragraph 220.127.116.11. The batch or lot of material can be identified by batch or lot number on each
Penetrant system material procurement SHALL meet the following requirements:
a. Materials SHALL comply with the current version of ASM 2644.
b. Except for solvent removers, bidders SHALL have material listed (or approved for listing) on the most
current revision of QPL-25135.
c. Contract and special purchase orders for procurement of materials SHALL require a certified test report
and a quality conformance sample submitted in accordance with the latest revision of ASM 2644.
d. Materials listed on QPL-25135 and those centrally procured using generic national stock numbers
(NSNs) need not comply with paragraph 18.104.22.168c.
Sampling Of Newly Received Materials.
Two samples are required from each batch or lot of penetrant, emulsifier or remover, and/or wet and dry developer
when received. If the supplier has submitted a quality conformance sample, (see paragraph 22.214.171.124.2.1), only one
additional sample will be required. Either one or two samples SHALL be taken from each batch or lot of penetrant,
emulsifier and remover, and wet and dry developer, when received and prior to use. One sample, either from the
supplier or locally taken, will be used to verify the Quality Conformance as described in paragraph 126.96.36.199. The second
sample, which may be larger than the first, will be retained by the using activities as a reference standard for periodic
process performance tests.
188.8.131.52.2.1 Quality Conformance Samples.
For all items except developer solids, a sample of not less than 1 quart or more than 1 gallon SHALL be taken from
each batch or lot of each material. For each batch or lot of wet developers in the dry condition, a 2-pound sample
SHALL be selected, and from each batch or lot of dry developer solids a 1 pound sample SHALL be selected.
184.108.40.206.2.2 Process Control Reference Sample.
These samples will be used as reference or master standards in comparing the performance of the in-use material. The
sample size will depend upon the workload which determines the frequency of process control testing. A suggested
sample size for high volume workload systems is 1 to 2 gallons (for all items except developer solids) from each batch
