ISO 6690:2007 specifies mechanical tests for milking machine installations in order to verify compliance of an installation or component with the requirements of ISO 5707. It also stipulates the accuracy requirements for the measuring instruments.
ISO 6690:2007 is applicable for testing new installations and for periodic checking of installations for efficiency of operation. Alternative test…
Live working - Protective clothing against the thermal hazards of an electric arc - Part 1-2: Test m...
This part of IEC 61482 specifies methods to test material and garments intended for use in heat- and flame-resistant clothing for workers exposed to electric arcs. In contrast to the test methods in IEC 61482-1-1 a directed and constrained electric arc in a low voltage circuit is used to classify material and clothing in defined arc protection classes.
The test methods specified in this document…
The purpose of ISO/TR 28980:2007 is to explain the changes relating to power measurements in the revised editions of ISO 8980-1 and ISO 8980-2.
In order to illustrate the issues raised, an inter-laboratory power measurement study was conducted on ten different lenses measured by nine organizations worldwide. Twenty-five focimeters of different types were used. The test lenses were spherically…
Industrial automation systems and integration — Parts library — Part 501: Reference dictionary for m...
ISO 13584-501:2007 specifies the requirements for an ISO-registered reference dictionary for measuring instruments with their properties and domains of values. ISO 13584-501:2007 also establishes and specifies the behaviour of a registration authority whose role is to develop, maintain and update this ISO-registered reference dictionary for measuring instruments. These measuring instruments…

Acoustics — Measurement of sound insulation in buildings and of building elements — Part 18: Laborat...
ISO 140-18:2006 specifies a laboratory method of measurement of the impact sound insulation of roofs, roof/ceiling systems and skylights excited by artificial rainfall. The results obtained can be used for assessing the noise to be produced by rainfall on a given building element in the room or space below. The results can also be used to compare rainfall sound insulation capabilities of building…
