E Terminology Relating to Quality and Statistics. The composite material forms are limited to continuous fiber or discontinuous fiber-reinforced composites in which the laminate is balanced and symmetric with respect to the test direction. The method may be used to determine the tensile properties of wet lay-up and pre-impregnated FRP composites fabricated on site or manufactured in a factory setting. Gaps between composite bands may not exceed 0.
Additional tests may be performed to qualify the work at each identified area. The certified applicator shall prove a minimum of 5 years experience in performing retrofits using FRP systems and submit a list of no fewer than 15 successful installations.

ASTM International – Standard References for ASTM D / DM – 10()
Acceptable minimum values for ultimate tensile strength, tensile modulus, and elongation shall not be below the submitted design values unless calculations are performed using the e7565 values that exhibit an acceptable capacity as per the original design demands and concept. If moisture is present, use the manufacturer suggested wet prime epoxy, if available.
If all tested samples of the sample batch do not meet the conditions of acceptance, it is recommended that 25 percent of all samples be tested.

ASTM D7565 Tensile Properties of FRP Matrix Composites for Civil Structures
Only epoxy resins will be accepted for construction of FRP systems referenced in this specification. Read in conjunction with the Contract Document. Any batch that exceeds the batch life shall not be used. Allow primer to become tacky to the touch.
FRP Specifications – Concrete Solutions
Design shall follow criteria in Section 1. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
Under certain application conditions, the system may be placed entirely by hand methods assuring a uniform, even final appearance. If one coupon does not achieve the design properties, additional coupons from the same sample shall be tested.
SCH fiber — primary carbon fiber, unidirectional.
Give our test engineers a call today for help configuring the best test machine and accessories according to ASTM D Well-adhered paint and concrete do not require removal.
The principal test variables could be the FRP constituents and fabrication method or the size or type of FRP laminate. The locations of the pull-off tests shall be representative and on flat surfaces. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Finish as specified between 24 and 72 hours after final application of epoxy. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Anchors may not be field fabricated. Anchor labels shall have the date of manufacture, the lot number and the minimum weight per unit length for each size.
Complete report and submit to Owner, engineer-of-record and FRP composite system manufacturer.
Variations in the radius along the vertical edge shall not exceed 0. Where no date is given for reference standards, the latest edition available on the date of the Notice of Invitation to Bid shall be used. The obtained tensile properties can be used for material specifications, quality control and assurance, structural design and analysis, and research and development.
