WATER PROOF 35S performs hydrostatic pressure test on fabrics in conformity according to the Standard UNI EN ISO 20811

The maximum pressure detected defines the water proof limits of a fabric subjected to the constant pressure increment.

Test results are expressed in mm.H2O or cm.H2O and are determined only after the first three water drops appear on outer surface in compliance with Reference Standard UNI, EN, ISO, ASTM, AATCC, etc..


The closure is designed to give a perfect tightness on sample blocked between the two flanges of the test area ensuring the minimum presence of leak just beside and anyhow recovered by lower basin; on request the WATER PROOF 35S includes auxiliary areas of 10, 26 and 28 cm2 to be applied on the original test area of 100 cm2 in compliance with AFNOR Standards.

Water proof 35S reaches the waterproof limits of pressure up to 20 m.H2O as standard measure range ideal for several test and ideal for water resistant samples as technical textiles or impermeable membranes approaching as per traditional methods.

Hydrostatic pressure test with Waterproof 35S can be performed on:
  • Technical textiles
  • Sportswear
  • Gore tex
  • Outdoor
  • Leather
  • Elastam
  • Tents
  • Bonded fabrics
  • Coated fabrics
  • Aerospace
  • Hi-tech membranes
  • Coatings
  • Automotive
  • Fabrics in general
  • Others

HMI Touch Screen with trend monitor new is a useful user interface for all endusers who has to manage the apparel during test performances also by remote control.

The easy setting of Water Proof 35S includes parameters setting, trend graph monitor and other useful functions and commands before, meanwhile and after test performances.
An internal storage memory allows the operator to collect up to a maximum of 20 savings to enable statistical evaluations and trend graphs analyes.

The Quality Certificate of the Water Proof 35S is released on request and issued by ACCREDIA, ENAC, UKAS, TUNAS accreditated institutes or by company factory certificate.

Water proof 35S is the automatic apparel able to offer a selection of test procedures:

  • DINAMIC, increase of hydrostatic pressure untill reaching the waterproof limits of material (3 waterdrops test);
  • STATIC, 24/48 hours keeping hydrostatic pressure stable at a setpoint;
  • PROFILE, custom trend pressure profile set by the user;


ASCII printer BWP35S

1) Built-in ASCII Printer: the print out of tests listing report is issued by the ASCII printer.
On test reports input data are reported as indicated below:

  • Company;
  • Address;
  • Country;
  • Operator;
  • Material;
  • Sample Nr.;
  • Supplier;
  • Comments;
  • Test results;
  • User signature;

Software for statistical analyses

2) Software BWP STAT04 with Runtime dongle key, allows to evaluate statistical calculations, trend graphs, real-time monitoring, logging functions managing parameters setting directly by remote; the application software adopts an add-ins application of Microsoft Office Excel and communicate with the apparel across USB or ETHERNET port onboard;
  • Parameters setting: pressing on reference cell it's possible to set across a dialog box the input value transmitting and receiving data to the Water Proof;
  • Saved data functions:
  • data storage is available through different functions in correspondence to an event or a command respectively programmed or queried by the user.The file format can be registered flexibly.
  • Versatility
  • Automatic Macro Start-up
  • recorded macro (set by the User) across event status On/Off.
  • Sound Files
  • The sound will be out-putted by the PLC relay and event turning ON.
  • Remote data management via modem
  • Modem Support:
  • Remote support offered by STA Branca Idealair;
  • Interactive data exchange
  • Data download from logic micro-controller;
  • Easy programming
  • For those who do not want to use the macro programme...
  • Character Change: display character change down to event On/Off.
  • Operation Formula: perform an operation on real time visualization and data conversion.
