Standards, grades & project editions.
A structured reference layer connecting industrial products with applicable standards, material families, grades and historical editions.
How BCUBE maps standards
We do not publish a single universal “all grades” list. Each grade is mapped to the product, governing specification, material family, service/application and edition where it is actually applicable.
Current vs project-specified editions
Technical pages will identify the current published edition while retaining relevant previous editions for procurement searches. Where a project specification names an older edition, the project document remains the controlling requirement.
Fastener standards
Examples include ISO 4014 for hexagon head bolts, ASTM A307 for carbon steel bolts/studs/threaded rod, ASTM A354 for quenched-and-tempered alloy steel fasteners, ASTM F1554 for anchor bolts, ASTM F3125 for high-strength structural bolts, ASTM A563/A563M for general carbon/alloy steel nuts, and ASTM A194/A194M for carbon, alloy and stainless steel nuts intended for high-pressure or high-temperature service. ASTM currently lists A194/A194M-26 as active and states that grade substitutions require purchaser permission.

Pipe-fitting standards
ASME B16.9 is used for factory-made wrought butt-welding fittings; ASME B16.11 covers forged socket-welding and threaded fittings. Branch outlet products require their specific outlet standard mapping.
Flange standards
ASME B16.5 covers standard pipe flanges and flanged fittings through NPS 24; B16.47 covers large-diameter steel flanges NPS 26–60; B16.36 covers orifice flanges; B16.48 covers line blanks.
Standards completeness audit
BCUBE's technical database is being audited by product family rather than by a single generic standards list. The audit separates product standards, material standards, mechanical-property standards, dimensional standards and service-specific bolting standards. This prevents a grade from being presented as universally applicable when the governing specification does not actually cover that product.
