Other Mechanical MASS-101

Mass Weight Set

This program is intended to provide a means for the participant laboratory to validate the technical competence of the laboratory in the calibration of small weights. This ASTM Class 1 weight kit contains 9 items ranging from 1 g to 100 g.

Reference values and associated uncertainties are provided by an accredited laboratory who concentrates on these measurements. Reference uncertainties vary from 1.6 µg to 12 µg depending on size.

Participants are expected to be familiar with handling and calibration of precision weights and have appropriate lab equipment and  measurement uncertainties for calibration of similar weights.

Other Mechanical MASS-216

Mass Level One

New class 1 - Pre-Qualification is required to participate in this ILC/PT. 

The primary purpose of this ILC/PT is to provide a means and opportunity for participants to demonstrate their proficiency (e.g. effective and appropriate use of the participant’s equipment, procedures, methods, and measurement uncertainty, and the ability to follow instructions) in the calibration of a Class 1 weight set.  

By participating, participants will demonstrate technical competence for the measurement of parameters associated with weights of similar size and weight class.  This weight set contains 10 weights ranging from 100 g to 500 mg. Participants will use their lab procedures to perform measurements of each weight in the set.

Participants are expected to be familiar with handling and calibration of mass standards, have all necessary auxiliary equipment to support the measurement and have measurement uncertainties appropriate for calibration of similar standards.

Other Mechanical MASS-317

Mass Level Three-A

The primary purpose of this ILC/PT is to provide a means and opportunity for participants to demonstrate their proficiency (e.g. effective and appropriate use of the participant’s equipment, procedures, methods, and measurement uncertainty, and the ability to follow instructions) in the calibration of a Class F weight set.  

By participating, participants will demonstrate technical competence for the measurement of parameters associated with weights of similar size and weight class.  This weight set contains 6 weights ranging from 10 lb to 0.5 lb.

Participants will use their lab procedures to perform measurements of each weight in the set.

Participants are expected to be familiar with handling and calibration of mass standards, have all necessary auxiliary equipment to support the measurement and have measurement uncertainties appropriate for calibration of similar standards.

Mass Weight Set / Class F

The primary purpose of this ILC/PT is to provide a means and opportunity for participants to demonstrate their proficiency (e.g. effective and appropriate use of the participant’s equipment, procedures, methods, and measurement uncertainty, and the ability to follow instructions) in the calibration of a Class F weight set.  

By participating, participants will demonstrate technical competence for the measurement of parameters associated with weights of similar size and weight class.  This weight set contains 8 weights ranging from 0.2 lb to 0.001 lb.

Participants will use their lab procedures to perform measurements of each weight in the set.

Participants are expected to be familiar with handling and calibration of mass standards, have all necessary auxiliary equipment to support the measurement and have measurement uncertainties appropriate for calibration of similar standards.

KITS, Other Mechanical PIPETTE-521

Fixed Volume Pipettes

The primary purpose of this ILC/PT is to determine the appropriateness and effectiveness of the participant’s equipment, procedures, training, and measurement uncertainty calculations relating to the measurement of POVA (Piston-operated volumetric apparatus) also known as Piston Pipettes.

By participating in this ILC organizations have an opportunity to demonstrate their proficiency (e.g., use of appropriate equipment, procedures, ability to follow instructions) in the calibration of a POVA. By participating, participants will demonstrate technical competence for the parameters associated with a POVA. Associated reported uncertainties will also be evaluated as part of this ILC/PT. 

This kit includes 5 Fixed Volume Pipettes ranging from 50µL to 1000µL.
