Introduction

Penetrant testing is one of the conventional non-destructive testing methods, mainly used to detect surface defects of metal or non-metal parts and is widely used in machine tools. Machinery, metallurgy, aerospace, aviation, petroleum, shipbuilding, railways and other fields. GB/T 18851 "Non-destructive Testing - Penetrant Testing" aims to standardize the conduct of penetrant testing activities. GB/T 18851 is proposed to consist of 6 parts constitute. --Part 1.General. The purpose is to specify the use of white light or ultraviolet light (UV-A, with a central wavelength of 365 nm) to detect the test material. A penetration testing method for open discontinuities on the material surface (such as cracks, heavy skin, folds, pores and unfused areas). -- Part 2.Inspection of penetrating materials. The purpose is to specify the technical requirements and inspections for type inspection and batch inspection of penetrating materials. Regulations. -- Part 3.Reference test blocks. The purpose is to specify two types of reference test blocks. --Part 4.Equipment. The purpose is to specify the characteristics of penetration testing equipment. -- Part 5.Penetrant testing at temperatures above 50°C. The purpose is to specify the test requirements specific to high temperatures (above 50°C) and and appropriate identification methods for test products. -- Part 6.Penetrant testing at temperatures below 10°C. The purpose is to specify the test requirements specific to low temperatures (below 10°C) and and appropriate identification methods for test products. This document is Part 1 of GB/T 18851.This revision clarifies and refines the test sequence, test equipment, display Requirements such as the recording and interpretation of the process and test results are important for promoting the standardization of penetration testing and ensuring product quality and service safety. significance.

1 Scope

This document specifies the use of white light or ultraviolet light (UV-A, with a central wavelength of 365 nm) to detect open discontinuities on the surface of the material being inspected (such as The method is mainly used for metal materials, but it can also be used for other non-porous materials. Materials that are resistant to penetration and inert to the penetrating material (such as castings, forgings, weldments, ceramics, etc.). This document specifies the test process and control requirements but does not include acceptance criteria. This document does not address the specific application of individual test systems. applicability information nor does it address requirements for testing equipment. Note 1.For methods for determining and monitoring the basic properties of penetrant testing products, see ISO 3452-2 and ISO 3452-3. NOTE 2 The term “discontinuity” as used in this document includes all indications that have not yet been evaluated for acceptance as acceptable or unacceptable. NOTE 3.CEN/TR 16638 gives a method for penetrant testing using actinic blue light.
