1 INTRODUCTION

1.1 Purpose

The aim of this document is to define the foreseen plan in order to verify physical properties of EPT-

HET-1 FM according to AD03 Chapter 5.5.2.1 Physical properties Measurements, AD01

Requirements and the ESA-Requirement EIDA R-023: which will be specified in this Procedure. The

requirements will be added to each specification.

1.2 Scope

This document applies to all activities related to EPT-HET FM properties verification campaign

performed by all institutions and personnel involved in the test.

The Test Report will be the contents of this procedure added by the results and pictures of the

measurements.

5 TEST PARAMETERS

5.1 Test requirements

EIDA R-050: The PI shall ensure that the difference between the measured mass of each STM unit

and FM unit with the respective nominal mass, specified in the relevant MICD, current at the time of

the STM and FM delivery, is less than 1%.

5.2 Test tolerances

EIDA R-440: The PI shall respect the following test tolerances, unless otherwise specified.

The test level tolerances are acc. to EIDA R-440 and the several Requirements mentioned in the

Overview.

5.3 Pass/fail criteria

For an Overview of the test pass/fail criteria, including their tolerance, see Tables 8-I / 8-II
