ASTM B117 Proficiency Program with Mass Loss – 550800

Need to evaluate your ASTM B117 salt spray exposure but do not have the equipment or process needed for precision corrosion-coupon mass measurements? Auto Technology Proficiency Testing Program #550800 separates the chamber exposure from the coupon measurement work.

Your laboratory performs the ASTM B117 exposure. Auto Technology performs the applicable pre- and post-exposure coupon cleaning and mass measurements using calibrated measurement equipment, allowing the resulting mass loss to be used for proficiency-testing comparison.

A B117 Proficiency Test Without In-House Mass Measurement

Accurate corrosion-coupon mass-loss work requires more than a salt spray chamber. Laboratories also need appropriate coupon-cleaning procedures and sufficiently capable measurement equipment. Program 550800 provides another route for laboratories that cannot perform, or prefer not to perform, those activities themselves.

Because Auto Technology performs the applicable measurement work, your laboratory can concentrate on specimen placement and the B117 exposure itself.

What Your Laboratory Does

• Maintain access to the applicable ASTM B117 standard
• Review the supplied proficiency-testing instructions
• Position and expose the supplied corrosion coupons
• Operate the salt spray chamber under the required B117 conditions
• Return the exposed coupons and required program information as instructed

What Auto Technology Does

• Performs the applicable pre-exposure mass measurements
• Performs applicable post-exposure coupon cleaning
• Performs post-exposure mass measurements using calibrated equipment
• Determines the applicable mass-loss results
• Provides the applicable statistical proficiency-testing evaluation

When Program 550800 Makes Sense

This option can be particularly useful when the question you need to answer is whether coupons exposed in your B117 process produce results consistent with the applicable proficiency-testing population.

• Your laboratory operates ASTM B117 but does not routinely perform coupon mass-loss measurements
• You do not have suitable analytical weighing capability
• You are commissioning or checking a salt spray chamber
• A chamber has recently been repaired, relocated, or modified
• You are preparing for important qualification or customer testing
• You want an external proficiency comparison while having ATC perform the measurement portion

Formal and Time-Sensitive Reporting Options

Formal proficiency-testing reports are issued twice each year and provide a confidential comparison with the applicable participating group.

When timing does not allow you to wait for the next reporting round, Auto Technology can also compare results with applicable historical proficiency-testing data and issue an individual report.

You Run ASTM B117. We Handle the Measurements.

Choose Program 550800 when your laboratory needs a B117 proficiency-testing comparison but wants Auto Technology to perform the applicable coupon cleaning and mass-measurement work.
