G Marking Documents: Product, Site and Conformity Evidence
Build a traceable G dossier with the national technical basis, product evidence, factory records and required conformity outputs.
Updated:
G marking is a Turkish national route for construction products placed on the market for permanent incorporation in construction works where mandatory CE marking does not apply. Determine the product, intended use and applicable technical specification before choosing the route. A cheaper quotation does not make G an alternative to a required CE assessment.
Identify the product and technical basis
Keep the manufacturer identity, product description, intended use, production sites and applicable national specification together. Where a national technical approval is relevant, verify its product and use scope. An unrelated standard number does not demonstrate that the route covers your product.
Link reports to production records
Retain applicable product-type test or calculation reports, sample identity, material acceptance and process-control records. Explain how existing evidence relates to the product supplied. A report for another formulation, plant or intended use needs an applicability assessment.
Check the output documents together
Match the required G conformity certificate and/or G conformity declaration and marking information to the assessed scope. Keep amendments and change notifications traceable. A CE performance declaration is not automatically the required national G declaration.
The official Turkish product-rules database distinguishes the national G conformity certificate and/or G conformity declaration from the CE performance declaration. Required manufacturer and assessment-body tasks follow the applicable national technical specification and attestation system. A document bearing a logo does not establish completed assessment.
The manufacturer remains responsible for the product, production controls, truthful records and required declaration and marking. An enquiry to Kayra can identify product scope, existing evidence and necessary technical tasks. Verify any assessment body’s actual designation for the product and task; this page does not claim that Kayra is designated to issue a G conformity certificate.
