NDT COMPLIANCE - THE PROPER
TEST FOR HIGH QUALITY LAMPS
Non-destructive testing relies on quality assurance and a rating
systems for tools to be used for the correct tasks, adhering to
industrial safety norms is a large factor behind the NDT market.

Product reliability must be tested to
meet industry codes and standards
before they are released to consumers.
These codes and standards showcase what
goes into product reliability testing,
especially if those companies create
products for different industries and
different countries. NDT is used in nearly
every manufacturing and engineering
process to inspect parts, welds, and
structures. Standards are constantly
getting upgraded to make NDT safe and
reliable for inspectors and the public.
Allowing for early detection of surface
and subsurface defects in products, NDT is
a useful tool for quality control in the
manufacturing process. For performing
NDT inspection, different types of
techniques can be used. Depending on the
application, it is important to ensure that
the components in use continue to
maintain their integrity, ensuring
usefulness and safety.
ASSURING SAFETY
Governmental agencies and regional
bodies such as The American Society of
Mechanical Engineers and The
International Organization for
Standardization are instituted across the
world to take stringent measures for
assuring safety and overseeing testing.
ASTM International is an important
organization that serves as an open forum
for the development of international
standards in NDT testing. The organization
was originally formed by a coalition of
scientists and engineers in 1898 to address
the frequent rail breaks affecting the fastgrowing
railroad industry. The group
developed a standard for the steel used to
fabricate rails. ASTM standard E3022
ensures the reliability and efficiency of
UV-A lamps used in fluorescent inspection
and NDT testing. The most recent revision,
as of September 2018, is ASTM E3022-18.
ASTM E3022 is the performance

using compliant lamps, it is
important to use a product
that was tested at the
standard required to find
said flaw
2 // The performance of a
compliant NDT lamp is
certified with rigorous
manufacturer testing and
recorded on a fully
serialized certificate

lamps used in liquid

requirement for ultraviolet A (UV-A), light
emitting diode (LED) lamps used in liquid
penetrant and magnetic particle testing.
This standard is intended primarily for UV
lamp manufacturers and includes
reporting and performance requirements
for UV-A LED lamps. It details procedures
and data collection used by UV-A lamp
manufacturers to certify LED lamps for
NDT use. It is not intended to be
referenced by end users. For a UV-A light
source lamp to be certified as E3022-
compliant, two levels of certification are
performed. This includes model-type
testing to qualify lamp designs, and
individual-unit testing to confirm every
single lamp that crosses the production
line is compliant.
Another compliance standard that
manufacturers of NDT lamps follow is
Rolls-Royce, RRES 90061. This is specified
for LED UV-A lamps, including test
requirements for the product design and
