GB/T 30470-2013Superabrasive products - Diamond wire saw (English PDF)

Foreword

GB/T 30470-2013 was issued on 31 December 2013 by the General Administration of Quality Supervision, Inspection and Quarantine and the Standardization Administration of the People's Republic of China, and has been in force since 1 September 2014.

The document is a recommended national standard: the /T in the designation marks it as recommended rather than compulsory.

1 Scope

China's national standard for diamond wire saws. A diamond wire is a steel cable carrying diamond abrasive on beads threaded along it, drawn through the workpiece in a continuous loop, and it cuts material that nothing else cuts economically: granite and marble in the quarry, reinforced concrete in demolition, and above all silicon. The transformation it produced in photovoltaics is worth stating - diamond wire replaced the slurry saws that used to slice silicon ingots into wafers, and because the wire is thinner it wastes far less silicon as kerf, cuts faster and allows thinner wafers, which is a direct reduction in the cost of solar electricity. China both makes and consumes most of the world's diamond wire. The standard specifies the product classification and codes, the structural types and codes, the technical requirements, the test methods, the safe use requirements, the inspection rules, and the marking, packaging, transport and storage.

This standard specifies the product classification and codes, the structural types and codes, the technical requirements, the test methods, the safe use requirements, the inspection rules, and the marking, packaging, transport and storage of diamond wire saws.

This standard applies to diamond wire saws used for mine quarrying, stone processing, engineering construction and similar purposes, referred to below as wire saws.
