GOST 7502-98 PDF

Full title and description

GOST 7502-98 — "Рулетки измерительные металлические. Технические условия" / "Measuring metal tapes. Specifications". The standard specifies technical requirements, testing and acceptance rules for metal measuring tapes (tape measures) of specified accuracy classes used for linear measurement.

Abstract

This interstate standard defines the constructional, metrological and quality requirements for metal measuring tapes (measuring reels/roulettes), including accuracy classes, permitted errors, marking, methods of verification, documentation, and packaging/transportation provisions for instruments manufactured to the standard. It is intended to ensure uniformity and traceability of tape-measure performance in industrial and surveying use.

Scope

The standard applies to metal measuring tapes (рулетки измерительные металлические) of the 2nd and 3rd accuracy classes and establishes requirements for their design, materials, dimensions, accuracy (permissible deviations), test and verification procedures, acceptance rules, marking, packaging and related documentation. It is intended for manufacturers, metrology services and users requiring standardized linear measurement tools.

Key topics and requirements

• Classification of measuring tapes by accuracy class (notably 2nd and 3rd classes) and the corresponding permissible measurement errors.
• Technical requirements for tape construction and materials (tape strip, coating/printing, case, end fittings and hook), and dimensional characteristics.
• Methods and procedures for verification, calibration (поверка) and acceptance testing, including documentation and certificates of verification.
• Marking, labelling and required information in accompanying documentation (designation, accuracy class, manufacturer, verification mark).
• Packaging, storage and transport conditions to preserve metrological characteristics.

Typical use and users

Manufacturers of measuring tapes and hand-held linear instruments, quality and metrology/verification laboratories, procurement specialists in construction and surveying, equipment resellers, and technical regulatory bodies. Typical applications include field and workshop linear measurements, construction, surveying and general industrial measurement tasks where portable tape measures are used.
