Viasys TS Test standards
TS, MICROBLENDER, HI/LO FLOW
1.0 SCOPE
This document defines a general test procedure that when used with the
specific Data Recording Sheet, (DRS) for the device under test, demonstrates
that (the Unit-in-test) it conforms to all product performance specifications and
requirements.
2.0 BACKGROUND
In addition to capturing pertinent data, the DRS is a test matrix containing specific
test parameters for the device being tested. All functional parameters stated in the
Device Specification are contained in the DRS. Although there are many
hardware configurations allowing for a variety of inlet and outlet adaptations, the
fundamental functional components, and sub-assemblies are common among the
Bird Microblender models. Several variations of the standard configuration are
available with "Primary" outlet ports located either at the bottom or on the left side,
with primary, auxiliary, and supply gas fittings customized (OEM) and with some
functional variations. Functional variations are detailed on corresponding DRSs.
DRSs are listed on the top level drawing and/or on the MINX network.
TEST STANDARD
3.0 APPLICABLE DOCUMENTS
3.1 Applicable DRS for the device under test.
3.2 Documents 91600, 91058 and 91059
3.3 Blender Re-processing Guide, 90636
4.0 GENERAL
4.1 Prior to testing, visually inspect the blender assembly to verify its
conformance to the blender assembly drawing and to aesthetic
requirements.
4.2 The unit to be tested must have been previously calibrated and the
"alarm/bypass" adjusted sufficient to prevent bypass leakage. Refer to
Manufacturing Assembly Guides, (MAG) 91600, 91058 and 91059 for precalibration, calibration and checkout details.
4.3 Re-processing (includes rework and re-test) of product is explained in
document 90636.

TEST STANDARD
SET-UP NOTES: (Refer to Figure 1)
1. Verify calibration of the test station O2 analyzer at 21% and 100% on a daily
(minimum) basis.
2. Install the UNIT-IN-TEST in the test system per Figure 1. Note; standard units
(e.g., 03800A) with a bottom located primary outlet are automatically
connected at the primary when installed in the fixture.
If the Microblender is fitted with an auxiliary outlet fitting, connect that fitting to
the auxiliary outlet hose on the test station. Keep all Microblender outlets
connected to the test station throughout the test unless otherwise directed.
3. Apply 50 Psig (AIR) to the air inlet and 50 Psig (O
) to the oxygen inlet.

4. For testing Microblenders with flow meters (“UltraBlenders”), hook up the
inputs to the Microblender in the normal manner to the test station. Connect
the outlet being tested directly to the Oxygen Analyzer via a tubing assembly
equivalent to that shown in Figure 2. Leave the opposite outlet disconnected
(no hose).
Adjust the flow to the required amount using the flow meter on the
Microblender outlet being tested.
It may be necessary to run the pump on the Oxygen Analyzer to supply it with
adequate gas during the tests.
