from the hose manufacturer or the hose assembly manufacturer.

4.4.3 Inspection lot. All hoses or hose assemblies of the same type and size offered to the

Government at one time shall be considered as a lot for the purpose of inspection.

4.4.3.1 First article samples. The samples shall be representative of the construction, workmanship,

components, and materials to be used during production. When a manufacturer is in continuous

production of the hose assemblies from one contract to another, submission of additional first article

samples for a new contract may be waived at the discretion of the acquiring activity (see 6.2).

4.4.3.2 Nonconformance of first article tests. All samples shall meet all of the contract requirements.

Failure of a sample unit to pass any test shall be cause for rejection of the entire lot and to not grant first

article approval.

4.4.3.2.1 Specimen tests. If a defect is found among samples for adhesion (4.6.2.), volume increase

(4.6.3), tensile strength (4.6.4), ultimate elongation (4.6.4), low temperature bend (4.6.10), ozone

resistance (4.6.12), or fuel color change (4.6.13) the lot shall be considered as failed.
