Many standards developing organizations are opening up access to standards relevant to COVID-19 during the pandemic. See below for a not comprehensive list of organizations and standards available to the public during this time of crisis. Free access to these standards is time limited and cannot be guaranteed.
AAMI (Association for the Advancement of Medical Instrumentation) has released three standards for public access, focusing on protective equipment and disinfection.
ASHRAE is providing free read-only access to selected standards and guidelines relating to air quality in buildings, aircraft, health care facilities, etc.
ISU users already have access to ASTM standards via ASTM Compass. For users who are not affiliated with ISU, ASTM has opened up a selection of standards related to COVID-19 response. Topics cover masks, gloves, medical gowns, respirators, and hand sanitizers.
As of April 2020, the American National Standards Institute (ANSI) has expanded their COVID-19 standards portal to include select IEC standards.
10 standards are included in IEEE's free-to-access COVID-19 response package.
ANSI is providing access to key ISO standards supporting biological evaluation of medical devices; protective clothing used in health care settings; and business continuity management, security, and resilience.
Predatory journals are a growing problem in academic fields, and are becoming particularly problematic in the sciences. Unscrupulous publishers take advantage of open access models (publishing models that allow anyone to access journal content without paying subscription costs). However, they publish junk science with questionable methods, results and conclusions. This has the potential to negatively affect future research. The motivations are to make money off of unsuspecting authors by charging them to publish articles, or for authors to unethically increase their publication counts for prestige.
It is important to identify and screen out predatory publishers so that they do not corrupt your literature reviews and research. First, search only reputable library and professional databases such as Medline, PubMed, CINAHL, or Engineering Village. Predatory journals will show up in Google searches. Second, read all research with a critical eye. Read ABOUT the publication, not just the article itself. Ask faculty or a librarian if you are unsure whether an article comes from a reputable journal.
