Natural-Stone Standards and Project Specifications<\/h1>\n

Turn design intent into a clear natural-stone specification covering material, finish, dimensions, performance, installation, tolerances, samples and acceptance.<\/p>\n

Standards answer defined questions<\/h2>\n

Product, test, design and execution standards each have a scope. Citing a number without identifying the product, use and current edition does not create a complete requirement.<\/p>\n

The project country determines the applicable legal and technical framework. Verify national annexes and local rules.<\/p>\n<\/section>\n

\n

Identify the material precisely<\/h2>\n

State commercial name, geological family, quarry or source where required, finish, cutting orientation, approved range and current batch process.<\/p>\n

Avoid promising natural stone as an exact uniform colour. Define acceptable variation with representative samples and slab photographs.<\/p>\n<\/section>\n

\n

Specify what affects performance<\/h2>\n

Connect relevant tests to the actual element: floor, tread, fa\u00e7ade panel, worktop or exterior paving. Include thickness, format, support, fixing and exposure.<\/p>\n

Do not copy irrelevant brochure values or substitute one test method for another.<\/p>\n

Responsibilities and submittals<\/h2>\n

State who designs fixings, validates calculations, surveys, approves layouts and inspects work. Require shop drawings, samples, data, method statements and prototypes at useful dates.<\/p>\n

Approval of appearance should not be mistaken for structural or regulatory validation.<\/p>\n<\/section>\n

\n

Acceptance and maintenance<\/h2>\n

Define inspection conditions, lighting, viewing distance, dry state and treatment of natural features. Establish a process for non-conforming work.<\/p>\n

Require cleaning, care and maintenance information with spare pieces and traceability records at handover.<\/p>\n<\/section>\n
