GB/T 5097-2020Non-destructive testing--Penetrant testing and magnetic particle testing--Viewing conditions (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 5097-2005 "Non-destructive testing - Penetrant testing

and magnetic particle testing - Viewing conditions". Compared with GB/T 5097-2005,

the main technical changes are as follows.

--- The scope of use of the standard is modified, which does not include the

requirements for the use of fluorescent light sources (see Chapter 1; see Chapter

1 of the 2005 edition);

--- The normative references are added (see Chapter 2);

--- The content of safety tips is modified (see Chapter 4; see Chapter 3 of the 2005

edition);

--- The requirements for light source and illuminance are added (see Chapter 5);

--- The chapter on qualified sensor spectral response is modified (see Chapter 6; see

Chapter 5 of the 2005 edition);

--- The calibration cycle is shortened from 24 months to 12 months (see Chapter 8;

see Chapter 7 of the 2005 edition).

The standard is translated from and identical to ISO 3059.2012 "Non-destructive testing

- Penetrant testing and magnetic particle testing - Viewing conditions".

The Chinese documents that have consistent correspondence with the international

documents normatively cited in this standard are as follows.

--- GB/T 2900.65-2004 Electrotechnical terminology - Lighting [IEC 60050-

845.1987, MOD]

--- GB/T 9445-2015 Non-destructive testing - Qualification and certification of NDT

personnel (ISO 9712.2012, IDT)

--- GB/T 12604.3-2013 Non-destructive testing - Terminology - Terms used in

penetrant testing (ISO 12706.2009, IDT)

This standard is proposed by and shall be under the jurisdiction of National Technical

Committee on Non-destructive testing of Standardization Administration of China

(SAC/TC56).

Non-destructive testing - Penetrant testing and magnetic

particle testing - Viewing conditions

1 Scope

This standard specifies the control requirements for the viewing conditions of magnetic

particle testing and penetrant testing, including the minimum requirements for the white

light illuminance and ultraviolet irradiance and their measurement methods, which are

applicable to the detection method of observing with the naked eye.

This standard does not include requirements for the use of actinic blue light sources.
