Company Info
Customer Portal
Organizations can create a Proficiency Testing (PT) Plan directly within their NAPT Customer Portal. Upon request, NAPT staff are available to assist with the development a PT plan. This is a collaborative process, usually involving a review of the organization’s scope of accreditation and the use of planning tools available in the portal. Once a proposed plan is drafted, it is the organization’s responsibility to review, approve, and notify NAPT of any desired enrollments. This free tool can be used to build a plan that includes both Full-Service kits and the use of the NAPT Intra Wizard, depending on the organization’s needs. Ultimately, the organization owns its PT Plan and is responsible for taking any necessary actions to comply with it. If the organization would like NAPT to follow the plan directly, it must clearly communicate that intent to NAPT staff.
General Info
No, we cannot. The participants are anonymous and may not be disclosed by NAPT. Please do not reach out to other labs you may know that are enrolled as that would be a violation of your enrollment.
No. It is the responsibility of the laboratory submitting results to calculate all uncertainties associated with their measurements. It is not NAPT’s role to state whether a reported uncertainty is correct or not; that oversight lies with your organization’s management and, ultimately, the accrediting body that granted your accreditation. The uncertainty of a measurement is a mathematical function calculated by the identity performing the measurement.
Screw-knob weights: Weights in this category are usually cleaned by wiping with a soft non-abrasive material such as high-grade cheesecloth, free from oils or other substances that would leave a residue of any kind on the surface. Occasionally, a weight will have foreign matter adhering to it that requires cleaning by using solvents, applied with a cloth. Ethyl alcohol is a good general solvent. If alcohol does not remove the foreign material, other solvents may be used. Alcohol is then used to remove any film left by the other solvents. Weights with internal cavities should not be immersed in the solvent to avoid the possibility that the fluid will penetrate the opening. Daily/Periodic Cleaning:(Non-sheet metal weights) Before each use clean all weights with a camel hair or other suitable soft brush to remove any particles that might have settled on the weight. Remember to pay special attention to the bottom surfaces, since these tend to be overlooked. One may also use a syringe bulb or compressed air to remove loose particles. If compressed air is used, especially if it comes from a can, the temperature of the weight may be affected, and the weight should not be used for at least 4 hours to allow the weight to return to thermal equilibrium with the environment. If particles are not removed easily, spot cleaning may be necessary. Spot Cleaning: Spot cleaning is recommended when foreign matter is observed on weights that cannot be removed using daily/periodic cleaning methods. Use cheesecloth dampened with ethyl alcohol and gently rub the weight surface in order to remove any residual or stubborn debris from the weight surface. If using alcohol does not remove the foreign debris, repeat the process using other solvents such as window cleaner or distilled water. If solvents other than distilled water and alcohol are used, the weights should be cleaned again using alcohol to remove any residual solvent from the weight. For sheet metal weights or other weights made out of aluminum, alcohol should never be used since alcohol can deteriorate aluminum. After spot cleaning, OIML Class (F2 to M3) weights should not be used for a period of at least 1 hours in order for the weight to return to thermal equilibrium with the environment. References:
The main goal of any enrollment is to compare measurements using your processes and reference values and evaluate your results against other like organizations.
For each enrollment, one set of data is standard. However, many organizations submit data for each technician qualified to perform the specific measurement. If you would like to add additional technicians to your enrollment, please contact NAPT. NAPT Members can have two additional data submittals per enrollment at no additional cost. For non-members, a small fee applies for each additional technician added.

NAPT staff will make every effort to accommodate special requests. However, if no prior arrangements are made, late fees will be assessed for not processing your ILC/PT within the designated timeframe.
