Foreword
This document was drafted in accordance with the provisions of GB/T 1.1-2020
"Directives for standardization - Part 1: Rules for the structure and drafting of
standardizing documents".
This document is Part 1 of GB/T 41105 "Non-destructive testing - Measurement and
evaluation of the X-ray tube voltage". GB/T 41105 is divided into 3 parts:
- Part 1: Voltage divider method;
- Part 2: Constancy check by the thick filter method;
- Part 3: Spectrometric method.
This document is identical to ISO 16526-1:2011 "Non-destructive testing -
Measurement and evaluation of the X-ray tube voltage - Part 1: Voltage divider method".
It adds two chapters "Normative references" and "Terms and definitions" to this
document.

Non-destructive testing - Measurement and evaluation of the
X-ray tube voltage - Part 1: Voltage divider method
1 Scope
This document specifies a method, for directly and absolutely measuring the average
high voltage, at the secondary side of the high-voltage generator of the X-ray system,
at a constant potential (DC). It establishes the corresponding relationship, between
checking the high-voltage output and the indicated value of the tube voltage, on the
control unit of the X-ray system.
This document is applicable to ensure the repeatable operation of X-ray systems. Tube
voltage affects the penetration properties of materials AND the contrast of X-ray images.
It also affects radiation protection related requirements.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
There are no terms and definitions, that need to be defined in this document.
4 Principles
The measurement principle of the voltage divider method is as shown in Figure 1.
