BS EN ISO 13385-1:2011 pdf free.Geometrical product specifications (GPS)一Dimensional measuring equipment
This part of ISO 13385 provides the most important design and metrological characteristics of callipers-with analogue indication: vemier scale or circular scale (dial), and with digital indication: digital display.
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

This is the error of indication when a full measuring face contact (3.2.1) is employed. For an example, see A.2.5.
NOTE The full surface contact error is a potential measure of the efect of the form deviation of both measuring faces.
Effect (error) due to crossed knife-edge distance, K (limited by KMPE)
This is the error of indication when the measurement is performed by using the crossed knife-edge jaws perpendicular to the length of jaws in a small cylindrical hole. For an example, see A.2.7.
MPE and MPL for a number of metrological characteristics
The maximum permissible error (MPE) is the extreme value of an error of a metrological characteristic permitted by the specification.
The maximum permissible limit (MPL) is the extreme value of a metrological characteristic permitted by the specification.
The manufacturer shall specify the MPE and MPL information for the calliper metrological characteristics listed in Figure 10. Unless otherwise specified by the manufacturer, the MPE/MPL values shall comply at any position within the measuring range and at any orientation of the calliper.
According to ISo 14978:2006, 7.5.1, MPEs shall be given as a continuous function (e.g. straight lines connecting given points); see ISO 14978:2006, 7.5.3, for the model. Figure 10 provides an example specification sheet for individual dimensions.
Indication in product documentation and data sheets
The indications shown in Table 3 are allowed for use in product documentation, drawings, data sheets, etc. as these altermatives reduce the amount of small text in subscripts to allow for improved visibility and clarity. An example data sheet is shown in Annex E.BS EN ISO 13385-1 pdf download.
