• 7.2) Watertight boundaries

Comments

The Manufacturer has provided a declaration about the control of, or the lack of Asbestos in this product.

The Hilti X-BT fasteners may be used to fasten materials in areas where welding or drilling for bolting is permissible. It is recommended that fasteners be installed no closer than 6 mm from the edge of a flange or cutout and no closer than 15 mm between fasteners. The following additional guidance is provided for applications on ship structures:

a) Acceptable applications:

• a1) The securing of grating panels
• a2) The securing of checker plate
• a3) The securing of electrical cable trays
• a4) The securing of electrical cable clips
• a5) The securing of joiner bulkhead tracks to plating in deck modules
• a6) The securing of light duty fixtures and light hangers
• a7) Securing of items (a1-a6) above in fire rated divisions
• a8) The securing of wall panel struts
• a9) The securing of exterior and interior outfitting
• a10) The securing of safety equipment
• a11) Use as grounding and bonding equipment

b) Acceptable locations:

• b1) On platform decks and flats
• b2) On non-tight bulkheads
• b3) On lower decks
• b4) On transverse side frames
• b5) In superstructures and deckhouse bulkheads
• b6) On Topside Deck members and plating
• b7) On Deck Modules
• b8) On members and plating in non-tight bulkheads
• b9) On members in longitudinal and traverse frames of hulls
• b10) On fire rated bulkheads of superstructures with a minimum thickness of 6mm provided the fasteners are installed from the side opposite to the insulated side. Fasteners are not to be installed behind, or imbedded in, structural insulation and the insulation in no way is disturbed.

c) Applications or locations where special care is recommended (see d below):

• c1) In members with significant thermal stresses
• c2) In highly stressed portions of members
• c3) In members subject to high, cyclic loads
• c4) Hangers for pipe systems with high thermal stresses
• c5) Hangers for sprinkler systems

d) Further guidance: The Hilti X-BT fasteners may be used for the applications where special care is recommended by following the manufacturer's recommendation. ABS approvals are general based on the product test reports furnished by recognized institutions and laboratories which may reflect specific local conditions. If any application is in a jurisdiction where the fasteners are subject to the approval process or specific guidelines are to be followed, the approved technical data or design guidelines take precedence over technical data presented herein.

ABS has used due diligence in the preparation of this certificate, and it represents the information on the product in the ABS Records as of the date and time the certificate is printed.

If the Rules and/or standards used in the PDA evaluation are revised or if there is a design modification (whichever occurs first), a PDA revalidation may be necessary.

The continued validity of the MA is dependent on completion of satisfactory audits as required by the ABS Rules. The validity of both PDA and MA entitles the product to receive a Confirmation of Product Type Approval.

Acceptance of product is limited to the "Intended Service" details prescribed in the certificate and as per applicable Rules and Standards.

This Certificate is valid for installation of the listed product on ABS units which exist or are under contract for construction on or prior to the effective date of the ABS Rules and standards applied at the time of PDA issuance. ABS makes no representations regarding Type Approval of the Product for use on vessels, MODUs or facilities built after the date of the ABS Rules used for this evaluation.

Type Approval requires Drawing Assessment, Prototype Testing and assessment of the manufacturer's quality assurance and quality control arrangements. The manufacturer is responsible to maintain compliance with all specifications applicable to the product design assessment. Unless specifically indicated in the description of the product, certification under type approval does not waive requirements for witnessed inspection or additional survey for product use on a vessel, MODU or facility intended to be ABS classed or that is presently in class with ABS.

Due to wide variety of specifications used in the products ABS has evaluated for Type Approval, it is part of our contract that; whether the standard is an ABS Rule or a non-ABS Rule, the Client has full responsibility for continued compliance with the standard.

Questions regarding the validity of ABS Rules or the need for supplemental testing or inspection of such products should, in all cases, be addressed to ABS.
