MANUFACTURER’S CERTIFICATE OF CONFORMITY
This document is provided by Land Instruments International, an original manufacturer
of opacity monitoring systems that are intended to comply with standards of performance
established by the US EPA 40CFR60, Appendix B, Performance Specification 1,
Performance Specifications for Opacity Monitors. This EPA specification references
ASTM Standard Practice D6216, which may be used by the manufacturer or supplier to
demonstrate that the designated opacity monitor meets those performance
requirements that can be tested and verified by the supplier prior to field installation.
Data in this summary document (Part 1) have been generated in compliance with the
procedures and specifications shown in the ASTM Standard Practice. These data
confirm that the designated opacity monitor meets or exceeds the requirements of this
Standard Practice.

PART 1 – DESIGN AND PERFORMANCE SPECIFICATIONS – TESTED AT
MANUFACTURER’S FACILITY
Conformance with design specifications is demonstrated by testing two separate opacity
monitors, each of which is representative of standard production. One opacity monitor
is selected and tested annually and the other is selected from either a production lot of
instruments not to exceed 20 in size, or from monthly production, and tested in
accordance with procedures described in ASTM Standard Practice D6216. The tests
associated with each of the above selected analysers is required to be repeated anytime
there is a critical component change that is substantial, hardware or software change,
or manufacturing process change that could affect performance with respect to said
design specifications. The test data derived from each of the above described two
analysers are summarized below, in Part 1 and Part 2, respectively.
