Because of this is is particularly important to use single dose skin preparation solutions, as bulk dispensers post known problems.
THE FABRIKATOR WAS UGLY, noisy, a fire hazard, and it smelled. Borislav got it for the kids in the neighborhood.
One snowy morning, in his work gloves, long coat, and fur hat, he loudly power-sawed through the wall of his kiosk. He duct-taped and stapled the fabrikator into place.
The neighborhood kids caught on instantly. His new venture was a big hit.
The fabrikator made little plastic toys from 3-D computer models. After a week, the fab’s dirt-cheap toys literally turned into dirt. The fabbed toys just crumbled away, into a waxy, non-toxic substance that the smaller kids tended to chew.
Borislav had naturally figured that the brief lifetime of these toys might discourage the kids from buying them. This just wasn’t so. This wasn’t a bug: this was a feature. Every day after school, an eager gang of kids clustered around Borislav’s green kiosk. They slapped down their tinny pocket change with mittened hands. Then they exulted, quarreled, and sometimes even punched each other over the shining fab-cards.
The happy kid would stick the fab-card (adorned with some glossily fraudulent pic of the toy) into the fabrikator’s slot. After a hot, deeply exciting moment of hissing, spraying, and stinking, the fab would burp up a freshly minted dinosaur, baby doll, or toy fireman.
Foot traffic always brought foot traffic. The grownups slowed as they crunched the snowy street. They cast an eye at the many temptations ranked behind Borislav’s windows. Then they would impulse-buy. A football scarf, maybe. A pack of tissues for a sneezy nose.
Once again he was ahead of the game: the only kiosk in town with a fabrikator….
This is very similar to what I saw when I visited Industrial Strength LLC Sharp Ass Needles, without the hubs, followed by cleaning and chemical passivation. They are ready to be sterilized and used. We use 304 SST and keep on file for every lot of needles we make a passivation certificate. We also have an … Read more How It’s Made – Hypodermic Needles
Neither are surgical implant materials. These are engineering specifications. *AISI and SAE do not establish standards for biocompatibility.
More detail: ASTM ? ANSI ? ISO ?
One thing to know is that ISO and ASTM are both international organizations for standards, but ISO is restricted to members of national standards bodies such as ANSI. Individuals or companies cannot become ISO members.
ASTM members are comprised of representatives of both government and stakeholders in related business, such as me. I joined ASTM in the mid 1990’s to represent the needs and learn more about the responsibilities of the body piercing business, and have been able to attend conferences, contribute my research based evaluations and vote for standards that affect us as body artists.
ISO voting is done for the USA by ANSI. ASTM makes recommendations to ANSI. ANSI has typically voted in accordance with the recommendations of the ASTM.
The 2013 update that my ASTM F04.12 committee just voted to approve for the most common steel alloy for surgical implant is also most the commonly used for body jewelry, F138.
ASTM F138-13a specifies chemical, mechanical and metallurgical refinements for 316 series steel alloys for surgical implant. It doesn’t really matter if the material is 316L, 316LVM, etc. The material is only acceptable for body jewelry when specified for human surgical implant and validated for this purpose to a peer reviewed scientific standard such as ASTM or ISO provides. AISI/SAE
As an aside: I don’t personally use steel alloy jewelry for initial piercings. I prefer pure unalloyed metals or simpler alloys with a greater margin of safety and less reactivity in the body.

A gravity displacement (class N) steam sterilization process can not reliably remove gases from hollow or porous items, resulting in areas that do not get sterilized, and the failure of the load. They should not be used for body jewelry, needles, tattoo tubes or textiles.

Effects of Non-Condensable Gases (NCGs) on Steam Sterilisation Processes
steam sterilisation process
non-condensable gases (NCGs)
process challenge device (PCD)
The dangers posed by non-condensable gases (NCGs) in steam sterilisation processes have long been underestimated. Biological indicators, or the best chemical indicators on the market, do not signal the presence of a NCG content of up to 10% in a sterilisation process so long as there is mixing of steam and NCGs in the sterilisation chamber.
What Titanium materials are best for body jewelry? My articles at https://jewelry.piercing.org/ and https://brnskll.com/shares/titanium-standards-why-not-g23/ explain that the two most effective Titanium standards are alloyed ASTM F136 and pure ASTM F67, the most common being the former as it is stronger, harder and easier to polish. Both are used for permanent surgical implants.
The actual procedure surface is referred to as an “aseptic field,” and is a sterilized surface that becomes exposed to air contact only at the beginning of the piercing procedure. The aseptic field used by most piercers is the sterile inside surface of a freshly opened large autoclave or sterile glove package, Statim cassette, rigid sterilization container, or sterilized tray. Once the package is opened, sterile tools, needles, jewelry, and disposables can be dropped onto the inside surface for use. The exterior of sterilized packages such as those containing the jewelry should not touch the aseptic field; the contents should be carefully dispensed onto it.
To minimize the risk of cross-contamination and to ensure that piercing room procedures are as clean as possible, many components of the tray setup must be disposable. Unless supplies are purchased presterilized* or will be sterilized in an autoclave immediately prior to the procedure, all disposables must be individually packaged in autoclave bags, sterilized, and remain intact in their pouches stored in enclosed, nonporous drawers or containers until use. Disposable materials that must be sterilized include: marking implements, piercing needles, corks or synthetic stoppers, elastic bands, swabs, and gauze.
* This includes only FDA-cleared items that are commercially sterilized according to accepted medical standards. The supplier must make documentation of appropriate sterilization available.
The following is to clarify the inconsistencies in the previous editions:

1) What is Anodizing?
Anodizing is a process where a coating is built up on the surface of certain metals (titanium, niobium, tantalum, aluminum, magnesium and zinc) by heating, with chemicals, or by electricity. In the case of titanium, the coating that is built up is a layer of titanium dioxide.
Some of my colleagues have already learned of this from my biomaterials presentations at APP 2010 and BMXnet conferences. This reflects upon imported jewelry, and the situations that can arise when quality controls are not normalized. So far, most of the response I get from US distributors of medical titanium alloys is for ELI material they only use domestic melts.
I’ve been talking with fellow ASTM committee members about international sourcing for F136 Ti in particular. They all only use domestic melts for ELI material from Perryman, ATI and Fort Wayne Metals for example . Therefore when companies in China or elsewhere want to make jewelry from F136 they either have to buy from a US or EU source that has a distributor in their area, eg Taiwan, or buy from an local mill melt, that quite possibly won’t meet FDA, BSI, ISO etc.
