Inspection stamps

Don t re-assign inspection stamps to another individual until a reasonable period of time has elapsed. 

If meat passes federal inspection, an inspection stamp (Fig. M-23) is affixed to the wholesale cuts or package to eissure the retailer and consumer that the products have been inspected. Products that do not pass inspection are denatured and rendered unusable for human consumption. 

Inspection Authority The National Board of Boiler and Pressure Vessel Inspectors is composed of the chief inspectors of states and municipalities in the United States and Canadian provinces which have made any pari of the Boiler and Pressure Vessel Code a legal requirement. This board promotes uniform enforcement of boiler and pressure-vessel rules. One of the board s imporiant activities is providing examinations for, and commissioning of, inspectors. Inspeciors so qualified and employed by an insurance company state, municipality, or Canadian province may inspect a pressure vessel and permit it to be stamped ASME—NB (National Board). An inspector employed by a vessel user may authorize the use of only the ASME stamp. The ASME Code Committee authorizes fabricators to use the various ASME stamps. The stamps, however, may be apphed to a vessel only with the approval of the inspector. 

Identifying inspection and test status is not just a matter of tying a label on a product. The status should be denoted by an authorized signature, stamp, mark, or other identity which is applied by the person making the accept/reject decision and which is secure... 

The standard doesn t require a procedure covering inspection and test status however, as clause 4.2 requires a documented quality system, you will need to document the methods employed to denote inspection and test status. If you use stamps you will need a register to allocate stamps to particular individuals and to indicate which stamps have been withdrawn. When a person hands in a stamp it is good practice to avoid using the same number for 12 months or so to prevent mistaken identity in any subsequent investigations. 

Don t stamp anything unless you have personally inspected the item. 

It must be pointed out that a Code stamp does not necessarily mean that the vessel is fabricated in accordance with critical nozzle dimensions or internal devices as required by the process. The Code inspector is only interested in those aspects that relate to the pressure-handling integrity of the vessel. The owner must do his own inspection to assure that nozzle locations are within tolerance, vessel internals are installed as designed, coatings are applied properly, etc. 

The simplest way to identify a specimen is to mark it with letters or numbers applied by stamping with a stencil or number punch. There is, of course, always the danger that the identification marks will be obliterated by corrosion. To guard against this, the several specimens in a test should be identified further by a record of their positions relative to each other or to their supporting device. Before specimens are taken from test their identity should be established in this manner unless inspection has already shown that the identification marks have been preserved. 

The stamp associated with the extreme hardness values (number 7, Fig. 4.12, left use STAMP.dat with program MULTI) is the next suspect It is identified and inspected on disassembly of the tablet press Due to mechanical wear, the movement of the stamp assembly is such that an above-average amount of granulate drops into cavity number 7, and is thus compressed to the limiting hardness supported by the granulate. The hardness for stamps 4, 8, and 11 tends to be low, and high for 12, but the data is insufficient to come to definite conclusions for these tools. The tablets from these stamps contaminated what would otherwise been a fairly acceptable product. Because... 

Every five years, all hoses should be tested to 1 times the container pressure at 130°F (54.4°C). Also, every five years the cylinders should be inspected per DOT requirements. For containers in continuous service, a visual inspection per CCA C-6, Standard for Visual Inspection of Steel Compressed Gas Cylinders may be conducted. The cylinder does not need to be emptied and cylinder should not be stamped. 

The inspection and test status of products is identified by using markings, authorized stamps, tags, labels, routing cards, inspection records, test software, physical location, or other suitable means to indicate the conformance or nonconformance of the product with regard to inspection and tests performed. The identification of inspection and test status is maintained, as necessary, throughout production and installation of the product to ensure that only product that has passed the required inspections and tests is dispatched, used, or installed. 

A series of letters and numbers are stamped on the shoulders of compressed gas tanks (see Fig. 5.2) to provide coded information for tank inspectors. These numbers tell under what codes the tank was made, the manufacturer, service pressure, serial number of the tank, and when it was last inspected and by whom. The manner in which the codes are laid out varies, and it may be difficult for an untrained person to interpret. However, to the compressed gas industry, they are important for preventing mistakes from the misuse of the containers. 

The ASME code consists of establishing the rules of safety governing the (i) design (ii) fabrication (iii) inspection during construction (materials, design, fabrication, examination, inspection, testing, certification and pressure relief) of boilers and pressure vessels. The rules were formulated to meet the needs and objectives of users, manufacturers and inspectors of pressure vessels. The formulated rules afford reasonable protection of life and property and provide a margin for deterioration in service in the useful lifetime. Any pressure boiler that is fabricated must meet the specifications and, after inspection, it is certified and provided with a stamp of approval. 

Failure Investigation. The clamp was nonmagnetic and the stamped identification on the side of the U-shaped shells indicated that they were fabricated from forged 304 austenitic stainless steel. Visual examination of the fracture surfaces revealed they were entirely brittle and exhibited a very coarse fracture morphology. Liquid penetrant inspection revealed the presence of additional cracks in the fractured half of the clamp. There was no cracking present in the high-strength steel fasteners. 

After the goods have been inspected, checked and classed in the grey room, according to quality and stamped, they are sewn together, end to end, by sewing machines especially constructed for this purpose. There are various types of sewing machines [Fig. 2-3(a) (b)]. The fabrics are usually sewn on circular machine. 

The proof marks employed by the inspectors in the U. S. Qovemment armories, and placed on all arms inspected by them, even if made in private armories, are V for viewed, and P for proved, together with the initial letters of the inspector s name, and are found stamped on each barrel. On many guns of the old model arms will be found, in addition to these marks, the head of an eagle. This is the mark that indicated that the barrels were made at the armory at Harper s Ferry, when those works were in operation. 

There is no set of standards that primarily applies to bins and since they are rarely designed for pressures greater than 15 psi, they do not require code stamps. They can, however, be designed, constructed, and inspected in accordance with certain sections of the ASME Code or combinations of codes.

Still on display in Wrightington, the rig is only partially assembled today. Inspection reveals a very sturdily constructed apparatus. Craven s pride in his craftsmanship is evident because his name is stamped into the top of the rig. 

All pressure equipment should be tested or inspected periodically. The frequency of tests and/or inspections varies, depending on the type of equipment, how often it is used, and the nature of its usage.

All pressure equipment should be tested or inspected periodically. The interval between tests or inspections is determined by the severity of the usage the equipment has received. Corrosive or otherwise hazardous service requires more frequent tests and inspections. Inspection data should be stamped on or attached to the equipment. Pressure vessels may be subjected to nondestructive inspections such as visual inspection, penetrant inspection, acoustic emissions recording, and radiography. However, hydrostatic proof tests are necessary for final acceptance. These tests should be as infrequent as possible. They should be performed before the vessel is placed in initial service, every 10 years thereafter, after a significant repair or modification, and if the vessel experiences ovrapressure or overtemperature.
