Dear members, Is it absolutely mandatory to test a product for EMC in an accredited lab under the suppliers declaration of conformity? If yes, where does it clearly say? This is what I found so far. It seem to me that it does not necessarily need to be accredited, but would need to comply with all the accreditation requirements. The question comes from the "upon request" of the sentence in section 2.948 (2).
And therefore, I would be OK for the FCC, if I know that the test results of a non-accredited lab that follows the test site calibration as per standards are equivalent to an accredited lab. Is that correct? §15.31 Measurement standards. (d) Field strength measurements shall be made, to the extent possible, on an open area test site. Test sites other than open area test sites may be employed if they are properly calibrated so that the measurement results correspond to what would be obtained from an open area test site. §2.948 Measurement facilities. (b) A laboratory that makes measurements of equipment subject to an equipment authorization under the certification procedure or Supplier's Declaration of Conformity shall compile a description of the measurement facilities employed. (1) The description of the measurement facilities shall contain the following information: (i) Location of the test site. (ii) Physical description of the test site accompanied by photographs that clearly show the details of the test site. (iii) A drawing showing the dimensions of the site, physical layout of all supporting structures, and all structures within 5 times the distance between the measuring antenna and the device being measured. (iv) Description of structures used to support the device being measured and the test instrumentation. (v) List of measuring equipment used. (vi) Information concerning the calibration of the measuring equipment, i.e., the date the equipment was last calibrated and how often the equipment is calibrated. (vii) For a measurement facility that will be used for testing radiated emissions, a plot of site attenuation data taken pursuant to paragraph (d) of this section. (2) The description of the measurement facilities shall be provided to a laboratory accreditation body upon request.
