2.1 Units of measurement
In this standard, data are expressed in both SI units and USC units. For a specific order item, unless otherwise stated, only one system of units shall be used, without combining data expressed in the other system.
2.2 Rounding
Unless otherwise stated in this standard, to determine conformance with the specified requirements, observed or calculated values shall be rounded to the nearest unit in the last right-hand place of figures used in expressing the limiting value, in accordance with ISO 31-0:1992, Annex B, Rule A.
NOTE For the purposes of this provision, the rounding method of ASTM E 29-04[1] is equivalent to ISO 31-0:1992, Annex B, Rule A.
2.3 Compliance to this standard
A quality system should be applied to assist compliance with the requirements of this standard.
NOTE ISO/TS 29001[2] gives sector-specific guidance on quality management systems.
A contract can specify that the manufacturer shall be responsible for complying with all of the applicable requirements of this International Standard. It shall be permissible for the purchaser to make any investigation necessary in order to be assured of compliance by the manufacturer and to reject any material that does not comply.
