ASTM F2329

F defines the two different lots and their associated sampling plans as follows:. A summary of the numerical differences between zstm two specifications related to coating thickness requirements for all materials is presented in the table: It is informational only and not an official part of the standard; the full astm f2329 of the standard itself must be referred to for its use and g2329. April 10, Authored by Alana Hochstein.

The amount of additional documentation beyond ASTM A requirements will vary depending on a number of optional astm f2329 the customer can specify under F If the customer specifies, the galvanizer will be required to provide astm f2329 average galvanizing temperature the fasteners will be exposed to.

Therefore, it asttm be clarified whether the plant has the ability to lubricate hardware after hot-dip galvanizing. Suppliers shall furnish certified test results from astm f2329 the shipping lots originated.

Otherwise, a third party will be required to apply the lubricant at an additional cost. Quenching According to F Paragraph 5. The test methods for appearance and smoothness under F shall be conducted for every batch lot by visual inspection astm f2329 accordance with methods provided in A Astm f2329 is the responsibility of astm f2329 user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations astm f2329 to use.

It is important to ensure the customer specifies which type of lot is required. Table 2 of F lists average coating thickness requirements for production lots, batch lots, and individual specimens. For example, a lot size of articles under the detection process requires testing of 11 samples for coating thickness, 11 samples astn visual appearance, and 3 samples for adhesion.

It is necessary for the galvanizer to communicate the bath temperature to the customer to ensure the end user understands astm f2329 effects the galvanizing temperature will have on the steel. ASTM F describes two different sampling plans for batch lots and production lots.

The coating thickness requirements of A Astm f2329 1 meet or exceed those of F Table 2 except for:. Best practice is to note f23299 bath temperature when galvanizing steel to F, although only the average bath temperature astm f2329 required.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Each bolt specification may list additional methods to prevent hydrogen embrittlement as well as place additional requirements on embrittlement testing which should be researched separately. The acceptance number in all astm f2329 is zero defects. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

It also provides for minor coating repairs. Work Item s – proposed revisions of this standard. It is important to note the acceptance criterion in all astm f2329 is zero defects. To determine how many samples are required to test for conformance based on the lot size, F refers to Table 3 of F, Practice for Fastener Sampling for Specified Mechanical Properties and Performance Inspection.

Furthermore, there are two types of production lots: F defines the two different lots and their associated sampling plans as follows: For long pieces anchor rods astm f2329 articles greater than five feet in lengthcoating thickness measurements must be taken on each end and in the middle of the article.

There astm f2329 three columns listing the number of test articles for three different inspection tests required astm f2329 F The differences in the types of lots entail different sampling plans, which specify the number of test articles for performing various test methods during inspection of the finished product. The type of production lot process will determine which column should be referenced for the sample size of each inspection criteria, as summarized in the table below, or per the F Astm f2329 Plan Flow Chart.

ASTM does not give any warranty express or implied or make any representation that the contents of astm f2329 abstract are accurate, complete or up to date. These instances can include when steel has been severely work hardened or when the galvanizing bath temperature exceeds the stress relief or tempering temperatures of the fasteners.

The coating thickness requirements of A Table 1 meet or exceed those of F Table 2 except for: Combining values from the two systems may result in non-conformance with the standard.

Nails and rivets are astm f2329 included in this specification. Adhesion testing is not typically performed when galvanizing to the requirements of A unless there is astm f2329 of an adhesion concern, but F requires adhesion testing stout knife test to be performed for the astm f2329 of articles listed in Table 1, and for every batch lot.

If certified test reports are not available, then the supplier must default to Sample Size C and conduct the tests required. However, if a purchaser also requires the galvanizer to inspect dimensional requirements of parts upon delivery, they must provide the galvanizer with the necessary tools and inspection gauges. The following tests shall be made to ensure f2392 astm f2329 zinc coating is being furnished in accordance with this specification: According to F Paragraph 5.

On the other hand, if embrittlement testing is necessary under F, it is to be conducted per ASTM F a wedge positioned and tensioned under a bolt headwhich is a different method than any of the methods described within A Paragraph 9. According to Astm f2329 G2329 of Table 1, It is only required astm f2329 conduct testing astm f2329 samples for coating thickness once every five batch lots. See excerpt of Table 1 below.

This method astm f2329 similar to an inspection of coating thickness on multi-specimen articles galvanized per ATSM Asmt Historical Version s – view previous versions of standard. The batch lot inspection process is more similar to inspection under A than inspection of production lots, but Table 1 f232 F has some additional requirements to consider.
