IEC 61335:1997 PDF

Scope: This International Standard applies to prospecting and mining bore-hole apparatus for X-ray fluorescence analysis and logging intended for the measurement and recording of values characterizing the elemental composition of rocks in the immediate vicinity of bore-hole walls. This standard applies to apparatus consisting of: - bore-hole logging instrument with a X-ray source and detection unit; - coaxial cable; - depth recording unit; - other instruments (power supply units, converters, recorders, processing and read-out instruments) if they are integral components of the apparatus. It does not apply to the bore-hole logging apparatus used for prospecting radioactive ore deposits. This standard specifies the types of apparatus, general technical requirements, performance or production unit acceptance tests, and gives recommendations about technical characteristics that are to be included in the operation and maintenance documentation (or certificate).
