In Melanie Trottman's story in the Wall Street Journal (pd. subs. req'd):

Some consumer advocates say the CPSC's action is long overdue, and say at least some of the cribs involved in the latest string of recalls were certified by the Juvenile Products Manufacturers Association, a U.S. trade group whose stamp of approval can lead consumers to believe a product is safe. "Clearly something in the voluntary standards is not catching these serious flaws," said Nancy Cowles, executive director of Kids in Danger, a Chicago child-safety advocacy group.

The recalls follow highly-publicized massive recent recalls of Simplicity cribs following at least two other deaths. That process was slowed and complicated by the bankruptcy of Simplicity; the private equity firm that had purchased its assets claimed no responsibility for its liabilities.

Provisions in the new Consumer Product Safety Improvement Act will subject durable nursery products, including cribs, to mandatory standards and stricter enforcement, following years of consumer groups at loggerheads with the crib manufacturers, their lobbyists, their lawyers, their associations and even the independent standards development firms such as ASTM that develop the voluntary standards now in use, as Annys Shin points out in her Washington Post story:

Consumer advocates have tried unsuccessfully for much of the past decade to get ASTM to develop a more comprehensive durability standard, said Donald Mays, senior director of product safety for Consumers Union.
