ASTM E165 NDT Cracked Aluminum Test Blocks Aluminum Alloy YM-A Dye
Penetrant Testing
NDT Cracked Aluminum Test Blocks
Cracked Aluminum Test Blocks compare sensitivity of different
penetrants or sensitivity of new and used penetrants. This is done
by processing one half of the block with used penetrant and the
other half with fresh penetrant. It is manufactured to meet the
ASME Boiler Pressure Code, Section V & III, and MIL-I-23135-C. The
cracked aluminum block is made from 2024 aluminum and is 3” x 2” x
3/8” thick. A 1/8" wide groove separates the blocks two sides to
facilitate side-by-side penetrant comparison.
It can be supplied with a Material Certification Form stating that
the block meets:
- ASME Boiler Vessel Code 1992 Edition, Section V Nondestructive
Examination, Article 6,
- Paragraph T-6-48.2 and 193 Addenda Paragraph T-653.2.
Aluminum alloy test block is composed of two parts with the same
size after the same test block is cut open, and marked with the
same serial number, respectively marked with A, B mark, A, B test
block should have A fine relative weighing crack pattern. Other
requirements of aluminum alloy test blocks shall be in accordance
with the relevant provisions of JB/T 9213.
Aluminum alloy test block is mainly used in the following two
situations:
A) Under normal use, check whether the penetration detection agent
can meet the requirements, and compare the advantages and
disadvantages of the two penetration detection agents;
B) Identification of penetrant detection methods for use at
non-standard temperatures.
Model:YM-A (type A)
Through the physical and chemical test type A block material for
LY12 aluminum alloy for materials, the chemical components conform
to the provisions of ASTM,GB/T3190
By means of a micrometer measurement block length is 76 + 0.1 ㎜,
and the width fifty + / - 0.1 ㎜, thick and ± 1 ㎜. Cut along the
length center evenly divided into two pieces, and in block A and B
and unity Numbers, block length orientation and plate rolling
direction. Milling, grinding the surface roughness after treatment
for Ra = 1.2 u m - 2.5 u m.
Color: Visual its color is silvery white.
Oxidizing property :In -55 ℃ ~ 200 ℃ - store between three years
not metamorphism, no oxidation,
Crack: In the same Numbers of the A and B block with dye penetrant
inspection method measured random crack 3 μ m, 3 μ m ~ 5 μ m and
more than 5 μ m open crack on one side not less than four, and
there are two above width is not more than 3 μ m open crack. Block
A and B on the surface crack distribution is similar.
