Pick-up and delivery service is available to customers located within 60 miles of our Hatfield, PA facility. We have three drivers on the road each day to move your orders back and forth as quickly as possible. This service is offered free of charge.

Invoicing

What payment terms do you offer to customers?

First-time customers are expected to pay for their first order with a credit card or check, unless credit terms have been approved in advance. We offer terms of net 30 days from the date of invoice to customers who have been approved after a credit and reference check. All customers wishing to establish an account should complete and return our Customer Information Form to provide us with that important information. The completed form can be faxed to 215-997-9414 or e-mailed to ar@labtesting.com.

Nondestructive Testing

What information do I need to provide in order to receive a quote?

Part drawing or size, quantity of parts to be inspected, location of area to be inspected (e.g. 100%, welds only, localized area) and the base specification.

How soon can I expect results for nondestructive testing?

In most cases, the standard turnaround is four working days for Magnetic Particle and Liquid Penetrant inspection, five working days for Radiography (X-ray), 20 to 25 working days for Ultrasonic (depending on the method required) and 10 working days for hydrostatic pressure testing. Same-day, next-day and 2nd-day expedited service is available at an additional cost. Please contact us for availability.

Ultrasonic Inspection (UT):

I have material for ultrasonic inspection. Should I be aware of any restrictions?

Tubing, pipe and bar stock must be free of surface coatings (oil, grease, heat-treat scale, urethane, etc.). The material must also be straight and without bends, kinks, or bowing.

Magnetic Particle Inspection (MPI):

Can you test through plating?

In most cases yes; allowable thickness limits vary (check the specification).

Can parts be sandblasted prior to testing?

Yes.

Does heat-treat scale or rust interfere with the inspection?

Yes, the material should be sandblasted prior to testing.

What is the maximum length you can inspect?

Our largest bench unit can test material up to 12 ft. long.

Do you demagnetize after inspection?

Yes, we demagnetize all material after inspection.

Do you apply a rust preventative after inspection?

Yes, it is applied to all parts after post-cleaning.

Liquid Penetrant Inspection (LPI):

Can you test through plating?

No.

Can parts be sandblasted?

No, unless pre-penetrant etching has been performed.

Do you perform pre-penetrant etching?

LTI does not provide this service. It is the customer’s responsibility to ensure this operation has been performed prior to Liquid Penetrant Inspection. Proof of pre-penetrant etching may be required depending upon the specification called out.

What is the maximum length you can inspect?

We can inspect material up to 40 ft. long.

Can you test magnetic parts?

Yes, although MPI is the better choice to prevent corrosion issues.

What types of materials can be inspected by LPI?

Non-magnetic metals (aluminum, titanium, magnesium, brass, stainless steels, etc.), glass, plastics, etc.

Can you perform fluorescent dye inspection after red visible dye inspection?

No, the red visible dye is dominant over the fluorescent dye. The test would be invalid.

Chemical Analysis

How big must the sample be for Atomic Emission Spectroscopy?

Ideally the sample should be at least 1’ square and 0.050’ thick to prevent leaking of light and gas from the aperture during excitation and to prevent the sample from melting during excitation. Samples of other configurations may be used if they can be mechanically altered to conform to the size requirement.

How much weight do I need for Inductively-Coupled Plasma Atomic Emissions Spectroscopy (ICP) Carbon/Sulfur/Nitrogen analysis?

The required weight will depend on the sample and material being tested. Generally, we would like to have at least 5 grams of material for analysis, which is the weight of a nickel. Whenever possible, more is better, to have extra material for rechecks if a material is found to be out of specification, or for resampling if a problem is encountered during sample preparation.

Why did you identify the material to that specification?

When the customer does not supply a specification, it is the analysts prerogative to assign one. There are thousands of specifications and usually more than one specification for each material type. The analyst will choose a corresponding specification for an unidentified material based upon the most generic criteria available [usually the Unified Numbering System for Metals (UNS)], such as one as close to the nominal requirements as possible or the more common material when the material meets several compositions.

Once you receive my order, what is the standard turnaround time?

Turnaround is a priority and we make every effort to complete spectroscopy orders within 3 business days following the day the order is received and processed in our Order Entry Department. Orders for wet chemistry and ICP analysis have a 5-day turnaround.

How much will the analysis cost?

The cost of the analysis will depend on the material, the available analytical methods, and the consideration of specific elements within the material that require special analytical techniques for accurate analysis. For a quote, please complete the Fast Quote form or contact Lee Dilks with details at ldilks@labtesting.com or 800-219-9095, ext. 183.

Mechanical Testing

How large must my material sample be for tensile, charpy and bend testing?

The required size will depend on the type of material, the type of test being performed and sometimes the specification. The guidelines on the Sizes Required for Testing sheet apply to most orders.

What is the standard turnaround time for tensile, charpy, bend and hardness testing?

On the day your order is received, it is processed in our Order Entry Department and sent to testing. Our standard turnaround time to perform the testing and prepare your Certified Test Report is usually 3 additional business days. Same-day, next-day, and 2nd-day rush services are available for most orders at an additional charge.

Metallography

What is the smallest sample you can mount and polish for a microstructure examination?

LTI mounts and polishes samples using two formats, either a 1 1/2 in. diameter or 2 in. diameter mount. In general, samples should be at least 1 1/2 in. Depending on the test, smaller samples may be sufficient. Please contact Alan Fabiszewski at afabiszewski@labtesting.com or 800-219-9095 ext. 210, for additional information.

Can the mounted sample and/or excess material be returned to the customer?

Yes, if requested by the customer. Mounted samples are typically retained by LTI for a period of 90 days and then discarded. Excess material in the Metallographic Laboratory is typically retained for a period of 30 days before discarding.

How soon can I expect results for routine metallurgical examinations?

In general, standard turnaround is 3 working days from receipt of the order. Expedited service is available at an additional cost.

Failure Analysis

I have a part that failed. What do I do to have it analyzed, what will it cost and how long will it take?

Questions concerning failure analysis techniques, pricing and turnaround times are handled on a case-by-case basis. Please contact Alan Fabiszewski at afabiszewskin@labtesting.com or 800-219-9095 ext. 210, for additional information.

Machining

What is the standard turnaround for most machining orders?

The standard turnaround for orders that require machining services only is determined by the size of the order, type of specimens, type and hardness of material, and equipment required for machining. We can give you a turnaround time once we have information on the work you are ordering. If you will need your specimens sooner, rush services are available for some orders at an additional charge.

What length and diameter piece of material do you need for a test specimen?

The required size will depend on the type of material, the type of test being performed and sometimes the specification. The guidelines on the Sizes Required for Testing sheet apply to most orders.

What information is needed to quote on a machining order?

In order to provide a quote, we will need a current print and answers on the type of material, size of material, material hardness, type and number of specimens required, applicable specifications and whether or not the material is welded.

What does the “W” (e.g. HRBW) stand for when certifying hardness done on the Rockwell B scale?

It will soon become an ASTM specification requirement that all users of Rockwell B indentors use a tungsten carbide ball, instead of steel. At the present, you can use either, but must indicate by HRBW, if using tungsten carbide when certifying or reporting values.

Calibration

What should I include on my purchase order?

In addition to a description of the services you are ordering, please include the calibration frequency for each instrument, the item’s grade or class when applicable, any internal reference numbers that you would like noted, and approval to subcontract orders when applicable.

How do I determine my calibration frequency?

The calibration frequency for tools, gages and other instruments vary by company. This is a customer decision that will depend on the requirements of your internal quality program, the working environment where the items are used and the frequency of use. The need for additional calibration may be driven by events such as customer requirements for a special order or possible damage to an instrument.

Will I need to send a Return Product/Merchandise/Goods Agreement (RPA/RMA/RGA) with my order?

No, we do not require an RPA/RMA/RGA to return your items. If you have specific shipping instructions that you would like us to follow, please include them on your purchase order.

Once you receive my order, how long will it take to calibrate?

Most orders will be completed within 6 working days after receipt at LTI. Turnaround times can vary for field service and sub-contracted orders, and will be quoted.
