If an organization uses a label or listing to indicate compliance with particular standards, the label or listing will be acceptaoie evidence, unless otherwise specified in the individual sections. In lieu of the label or listing, the Contractor shall submit a certificate from an independent testing organization, which is competent to perform acceptable test. The certificate shall state that the item has been tested in accordance with the specified organization's test methods and that the item conforms to the specified organiza tion's standard. For materials and equipment whose compliance with organizational standards or specifications is not regu lated by an organization using its own listing or la.nel as proof of compliance, a certificate of compliance fro... the manufacturer shall be submitted for anoroval. The certifi- cate shall identify the manufacturer, the product, and the referenced standard and shall si.mpiy state that the manufac turer certifies that the product conforms to all requirements of the project specification and of the referenced standards listed. E. Certified Test Reports: Before delivery of materials and equipment, certified copies of all test reports specified in the individual sections shall be submitted for approval. F. Certificates of Conformance or Compliance: Submit certifi cation from the manufacturer attesting that materials and equipment to be furnished for this project comply with the requirements of this specification and of the reference publi cations. Preprinted certifications will not be acceptable; certifications shall be in the original. The certification shall not contain statements that could be interpreted to imply that the product does not meet all requirements spe cified, such as "as good as"' "achieve the same end use and results as materials formulated in accordance with the re ferenced publications"; "equal or e.xceed the service and performance of the specified material". The certification shall simply state that the product conforms to the require ments specified. ?.J\RT 3 - EXECUTION' 3.01 INTERPRET.ATION OF PL.ANS A. In general, the drawings of the mechanical systems and equip ment are to scale. However, to determine e.xact locations of walls and partitions, the Contractor should consult t.he archi,tectural and/or structural drawings which are dimensioned. Drawings shall not taKe precedence over field measurements. B. Plans of piping and ductwork, although shown on scale drawings, are diagrammatic only. They are intended to indirate size and/or capacity where stipulated, approximate location and/or direction, and approximate general arrangement of construction. If it is found, before installation of any or all construction phases, thac a more convenient, suitable or workable arrange ment of any or all phases of the project would result by varying or altering the arrangement indicated on the drawings, the Architect/Engineer may require the Contractor to change submitted for appro- Iistiag to indicate e label or listing rwise specified in label or listing, e from an independent to perform acceptable the Item has been organization's test e specified organiza- pment whose compliance cations IS not regu- isLing or lat^^ei as mpliance frc^j the oval.
