Full title and description

JIS B 7512:2018 — Steel tape measures. This Japanese Industrial Standard specifies requirements, classification, performance, marking and inspection requirements for steel tape measures with nominal lengths from 0.5 m up to 200 m.

Abstract

JIS B 7512:2018 defines types, classes and nominal sizes for steel tape measures and sets requirements for length tolerances, graduation, straightness, uprightness, appearance, construction, materials, measurement and inspection methods, and product marking and designation. It is intended to ensure uniformity and interchangeability of tape-measure products and to provide criteria for conformity assessment.

Scope

This Standard applies to steel tape measures (巻尺) with nominal lengths from 0.5 m to 200 m and covers their classification, nominal sizes, performance requirements (including tolerances on length), graduation and scale requirements, appearance and construction, materials, measurement methods, inspection, product designation and marking. It is intended for manufacturers, testers and procurement bodies specifying steel tape-measure performance and conformity.

Key topics and requirements

• Types and classes: definition of product types and grading/classification for tape measures.
• Nominal length and tolerances: permitted nominal sizes (0.5 m to 200 m) and allowable length tolerances for accuracy.
• Performance: uprightness, straightness of scale side face and other mechanical performance criteria.
• Scale and graduation: requirements for scale markings, units, legibility and graduation accuracy.
• Appearance and construction: casing, end fittings, hook behavior and constructional requirements.
• Materials: acceptable materials for blade, case and fittings and related requirements.
• Measurement and inspection methods: standardized test methods for verifying dimensional and performance requirements.
• Designation and marking: product identification, class/grade marking, length marking and manufacturer identification.

These topics are taken from the standard's table of contents and normative clauses.

Typical use and users

Used by manufacturers of tape measures for product design and quality control, testing and calibration laboratories, procurement specialists in construction and manufacturing, regulatory bodies that reference JIS for conformity, and distributors who need to confirm product compliance with Japanese Industrial Standards. The standard is referenced where consistent measurement accuracy and interchangeability of tape measures are required.
