Material measures of length
For Material measures of length, annex is Annex X (MI-008); accuracy class is I; condition is between two non-consecutive scale marks; maximum permissible error is ± (0,1 + 0,1 L) mm, where L is length rounded up to next whole metre; c = 0,1 mm for terminal interval bounded by a surface, recorded from its source on 2026-08-05.

What the source says
ANNEX X MATERIAL MEASURES (MI-008) CHAPTER I Material measures of length The relevant essential requirements of Annex I, the specific requirements of this Annex and the conformity assessment procedures listed in this chapter, apply to material measures of length defined below. However, the requirement for the supply of a copy of declarations of conformity may be interpreted as applying to a batch or consignment rather than each individual instrument. DEFINITIONS Material measure of length | An instrument comprising scale marks whose distances are given in legal units of length. | SPECIFIC REQUIREMENTS Reference Conditions 1.1. | For tapes of length equal to or greater than 5 metres, the maximum permissible errors (MPEs) are to be met when a tractive force of fifty newtons or other force values as specified by the manufacturer and marked on the tape accordingly, or in the case of rigid or semi-rigid measures no tractive force is needed, is applied. | 1.2. | The reference temperature is 20 °C unless otherwise specified by the manufacturer and marked on the measure accordingly. | MPEs 2. | The MPE, positive or negative in mm, between two non-consecutive scale marks is (a + bL), where:
