Long tapes and short rules
Give the material, total length and scale division. For a retractable tape, report a loose or damaged hook as found; for a steel survey tape, include any specified tension and support conditions from its documentation. A diameter tape needs its scale identified separately.
Select marks from the work
A rule used to set a fixture over a short span and a tape used to check a long assembly rarely need the same points. List the marks that occur on the job sheet and whether both faces or scale systems are used. RTS can confirm the lengths it can accommodate.
The starting reference and support conditions
A retractable tape may be used with its hook pulled against an edge or pushed against an inside face. Identify the mode required by your procedure and report a loose or damaged hook without altering it first. For a rule, state whether the end itself or an engraved line is the zero reference. Record each scale face if the instrument carries more than one graduation system.
A long tape's comparison needs the specified tension and support arrangement, along with the conditions recorded on the report. Send the manufacturer's information where available. Ask for the working intervals that matter to your drawings, and identify any requested correction values with their sign. A diameter or circumference tape requires its own scale description; preserve the marked units and intended reading instead of treating it as a general linear tape.
PI tapes and diameter-reading scales
A diameter tape reads a different quantity from a tape marked for circumference or straight length. Copy the exact scale description, units and graduation from the tape. Send the manufacturer's reading instructions with the enquiry, especially where a vernier is used. State whether the requested result is a linear graduation check or verification of a diameter-reading function.
CC-4643 groups measuring tape, pie tape and dip tape in a permanent-facility entry from 0 to 50 m at least count 1 mm, using a scale and tape calibration system. Those conditions must be matched to the requested work. The entry does not by itself establish coverage of a finer vernier scale or circular diameter verification on a particular product.
Give the nominal working sizes and the specified support and tension conditions for review. Keep a previous certificate with the request if corrections are already used in production. Record whether those corrections refer to length, circumference or diameter; the units alone may not tell the next inspector which quantity was checked.
Handover at a commissioning site
Mark contractor-owned tapes separately from tools transferred to the plant. Give each long tape its storage and return address. Keep the reel and end fittings identified, and disclose kinks, corrosion or repaired sections before shipment. For a large batch, retain a photograph of each starting reference with the instrument list.
Standard scale reference intervals
For a standard scale, identify its construction, graduation, reference mark and the intervals requiring values. The word standard may describe its role in your laboratory rather than its accuracy or scope eligibility. Send the existing certificate and measuring procedure. RTS will distinguish a rule matching a listed scope entry from a finer reference scale requiring a different method and reporting arrangement.
