  CHAPTER I--MINE SAFETY AND HEALTH ADMINISTRATION, DEPARTMENT OF LABOR
 
PART 74--COAL MINE DUST PERSONAL SAMPLER UNITS--Table of Contents
 
Sec. 74.7  Certificate of approval.

    (a) Upon completion of the testing of a coal mine dust personal 
sampler unit or the pump unit thereof, the National Institute for 
Occupational Safety and Health or MSHA, as appropriate, shall issue to 
the applicant either a certificate of approval or a written notice of 
disapproval, as the case may require. The National Institute for 
Occupational Safety and Health shall not issue a certificate of approval 
for a coal mine dust personal sampler unit unless MSHA has issued a 
certificate of approval for the pump unit thereof. No informal 
notification of approval will be issued. If a certificate of approval is 
issued, no test data or detailed results of tests will accompany such 
approval. If a notice of disapproval is issued, it will be accompanied 
by details of the defects, resulting in disapproval, with a view to 
possible correction.
    (b) A certificate of approval will be accompanied by a list of the 
drawings and specifications, covering the details of design and 
construction of the coal mine dust personal sampler unit or the pump 
unit thereof upon which the certificate of approval is based. The 
applicant shall keep exact duplicates of the drawings and specifications 
submitted to the National Institute for Occupational Safety and Health 
and to MSHA relating to the sampler unit or pump unit thereof which has 
received a certificate of approval. The approved drawings and 
specifications shall be adhered to exactly in the production of the 
certified sampler unit, including the pump unit thereof, for commercial 
purposes. In addition, the applicant shall observe such procedures for, 
and keep such records of, the control of component parts as either MSHA 
or Institute may in writing require as a condition of certification.
