This specification defines the masses to be used when testing rescue systems and components. The masses represent personnel and equipment that may be attached to a rescue system or components. However, the masses do not represent any particular type or kind of rescuer or equipment. The masses shall be classified as follows: Type I; Type II; Type III; Type IV; and Type V.

1.1 This specification defines the masses to be used when testing rescue systems and components.

1.2 The masses represent personnel and equipment that may be attached to a rescue system or components. However, the masses do not represent any particular type or kind of rescuer or equipment.

1.2.1 The masses chosen have been used in the past or are in current use in testing of rescue systems and components. Limiting testing to the masses listed in this specification allows meaningful comparisons between past, current, and future test results.

1.3 The user of this specification shall determine which mass(es) represent(s) the personnel and equipment attached to the system or component under test.

1.4 For the purposes of this specification, mass and weight are synonymous when the object(s) representing the mass(es) are weighed in air anywhere on Earth.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
