Sec. 20.11  Material required for MSHA records.

    In order that MSHA may know exactly what it has tested and approved, 
detailed records are kept covering each investigation. These include 
drawings and actual equipment, as follows:
    (a) Drawings. The original drawings submitted with the application 
for the tests and the final drawings which the manufacturer must submit 
to MSHA before approval is granted, to show the details of the lamp as 
approved, are retained. These drawings are used to identify the lamp and 
its parts in the approval and as a means of checking the future 
commercial product of the manufacturer.
    (b) Equipment. (1) If MSHA so desires, parts of the lamps which are 
used in the tests will be retained as a permanent record of the 
investigation and of the lamps submitted.
    (2) If the lamp is approved, MSHA will require the manufacturer, as 
soon as his first manufactured lamps are available, to submit one 
complete lamp, with the approval plate attached, as a record of his 
commercial product.
